At first, Alastor gets a kick out of forcing Vox to do manual, menial labor, something he knows Vox would’ve hated under normal circumstances. Vox always saw hands-on work as beneath him, associating it with the poor and preferring more “cerebral” work. However, the novelty eventually wears off when it becomes clear that The New Vox actually enjoys his handyman work and doesn’t/can’t perceive it as the insult that Alastor meant it as.

Interactive mouthpiece opens new opportunities for health data, assistive technology, and hands-free interactions

Interactive mouthpiece opens new opportunities for health data, assistive technology, and hands-free interactions

When you think about hands-free devices, you might picture Alexa and other voice-activated in-home assistants, Bluetooth earpieces, or asking Siri to make a phone call in your car. You might not imagine using your mouth to communicate with other devices like a computer or a phone remotely. 

Thinking outside the box, MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) and Aarhus University researchers have now engineered “MouthIO,” a dental brace that can be fabricated with sensors and feedback components to capture in-mouth interactions and data. This interactive wearable could eventually assist dentists and other doctors with collecting health data and help motor-impaired individuals interact with a phone, computer, or fitness tracker using their mouths.

Resembling an electronic retainer, MouthIO is a see-through brace that fits the specifications of your upper or lower set of teeth from a scan. The researchers created a plugin for the modeling software Blender to help users tailor the device to fit a dental scan, where you can then 3D print your design in dental resin. This computer-aided design tool allows users to digitally customize a panel (called PCB housing) on the side to integrate electronic components like batteries, sensors (including detectors for temperature and acceleration, as well as tongue-touch sensors), and actuators (like vibration motors and LEDs for feedback). You can also place small electronics outside of the PCB housing on individual teeth.

The active mouth

“The mouth is a really interesting place for an interactive wearable and can open up many opportunities, but has remained largely unexplored due to its complexity,” says senior author Michael Wessely, a former CSAIL postdoc and senior author on a paper about MouthIO who is now an assistant professor at Aarhus University. “This compact, humid environment has elaborate geometries, making it hard to build a wearable interface to place inside. With MouthIO, though, we’ve developed a new kind of device that’s comfortable, safe, and almost invisible to others. Dentists and other doctors are eager about MouthIO for its potential to provide new health insights, tracking things like teeth grinding and potentially bacteria in your saliva.”

The excitement for MouthIO’s potential in health monitoring stems from initial experiments. The team found that their device could track bruxism (the habit of grinding teeth) by embedding an accelerometer within the brace to track jaw movements. When attached to the lower set of teeth, MouthIO detected when users grind and bite, with the data charted to show how often users did each.

Wessely and his colleagues’ customizable brace could one day help users with motor impairments, too. The team connected small touchpads to MouthIO, helping detect when a user’s tongue taps their teeth. These interactions could be sent via Bluetooth to scroll across a webpage, for example, allowing the tongue to act as a “third hand” to open up a new avenue for hands-free interaction.

“MouthIO is a great example how miniature electronics now allow us to integrate sensing into a broad range of everyday interactions,” says study co-author Stefanie Mueller, the TIBCO Career Development Associate Professor in the MIT departments of Electrical Engineering and Computer Science and Mechanical Engineering and leader of the HCI Engineering Group at CSAIL. “I’m especially excited about the potential to help improve accessibility and track potential health issues among users.”

Molding and making MouthIO

To get a 3D model of your teeth, you can first create a physical impression and fill it with plaster. You can then scan your mold with a mobile app like Polycam and upload that to Blender. Using the researchers’ plugin within this program, you can clean up your dental scan to outline a precise brace design. Finally, you 3D print your digital creation in clear dental resin, where the electronic components can then be soldered on. Users can create a standard brace that covers their teeth, or opt for an “open-bite” design within their Blender plugin. The latter fits more like open-finger gloves, exposing the tips of your teeth, which helps users avoid lisping and talk naturally.

This “do it yourself” method costs roughly $15 to produce and takes two hours to be 3D-printed. MouthIO can also be fabricated with a more expensive, professional-level teeth scanner similar to what dentists and orthodontists use, which is faster and less labor-intensive.

Compared to its closed counterpart, which fully covers your teeth, the researchers view the open-bite design as a more comfortable option. The team preferred to use it for beverage monitoring experiments, where they fabricated a brace capable of alerting users when a drink was too hot. This iteration of MouthIO had a temperature sensor and a monitor embedded within the PCB housing that vibrated when a drink exceeded 65 degrees Celsius (or 149 degrees Fahrenheit). This could help individuals with mouth numbness better understand what they’re consuming.

In a user study, participants also preferred the open-bite version of MouthIO. “We found that our device could be suitable for everyday use in the future,” says study lead author and Aarhus University PhD student Yijing Jiang. “Since the tongue can touch the front teeth in our open-bite design, users don’t have a lisp. This made users feel more comfortable wearing the device during extended periods with breaks, similar to how people use retainers.”

The team’s initial findings indicate that MouthIO is a cost-effective, accessible, and customizable interface, and the team is working on a more long-term study to evaluate its viability further. They’re looking to improve its design, including experimenting with more flexible materials, and placing it in other parts of the mouth, like the cheek and the palate. Among these ideas, the researchers have already prototyped two new designs for MouthIO: a single-sided brace for even higher comfort when wearing MouthIO while also being fully invisible to others, and another fully capable of wireless charging and communication.

Jiang, Mueller, and Wessely’s co-authors include PhD student Julia Kleinau, master’s student Till Max Eckroth, and associate professor Eve Hoggan, all of Aarhus University. Their work was supported by a Novo Nordisk Foundation grant and was presented at ACM’s Symposium on User Interface Software and Technology.

Studying astrophysically relevant plasma physics

New Post has been published on https://thedigitalinsider.com/studying-astrophysically-relevant-plasma-physics/

Studying astrophysically relevant plasma physics

Thomas Varnish loves his hobbies — knitting, baking, pottery — it’s a long list. His latest interest is analog film photography. A picture with his mother and another with his boyfriend are just a few of Varnish’s favorites. “These moments of human connection are the ones I like,” he says.

Varnish’s love of capturing a fleeting moment on film translates to his research when he conducts laser interferometry on plasmas using off-the-shelf cameras. At the Department of Nuclear Science and Engineering, the third-year doctoral student studies various facets of astrophysically relevant fundamental plasma physics under the supervision of Professor Jack Hare.

It’s an area of research that Varnish arrived at organically.

A childhood fueled by science

Growing up in Warwickshire, England, Varnish fell in love with lab experiments as a middle-schooler after joining the science club. He remembers graduating from the classic egg-drop experiment to tracking the trajectory of a catapult, and eventually building his own model electromagnetic launch system. It was a set of electromagnets and sensors spaced along a straight track that could accelerate magnets and shoot them out the end. Varnish demonstrated the system by using it to pop balloons. Later, in high school, being a part of the robotics club team got him building a team of robots to compete in RoboCup, an international robot soccer competition. Varnish also joined the astronomy club, which helped seed an interest in the adjacent field of astrophysics.

Varnish moved on to Imperial College London to study physics as an undergraduate but he was still shopping around for definitive research interests. Always a hands-on science student, Varnish decided to give astronomy instrumentation a whirl during a summer school session in Canada.

However, even this discipline didn’t quite seem to stick until he came upon a lab at Imperial conducting research in experimental astrophysics. Called MAGPIE (The Mega Ampere Generator for Plasma Implosion Experiments), the facility merged two of Varnish’s greatest loves: hands-on experiments and astrophysics. Varnish eventually completed an undergraduate research opportunity (UROP) project at MAGPIE under the guidance of Hare, his current advisor, who was then a postdoc at the MAGPIE lab at Imperial College.

Part of Varnish’s research for his master’s degree at Imperial involved stitching together observations from the retired Herschel Space Telescope to create the deepest far-infrared image ever made by the instrument. The research also used statistical techniques to understand the patterns of brightness distribution in the images and to trace them to specific combinations of galaxy occurrences. By studying patterns in the brightness of a patch of dark sky, Varnish could discern the population of galaxies in the region.

Move to MIT

Varnish followed Hare (and a dream of studying astrophysics) to MIT, where he primarily focuses on plasma in the context of astrophysical environments. He studies experimental pulsed-power-driven magnetic reconnection in the presence of a guide field.

Key to Varnish’s experiments is a pulsed-power facility, which is essentially a large capacitor capable of releasing a significant surge of current. The electricity passes through (and vaporizes) thin wires in a vacuum chamber to create a plasma. At MIT, the facility currently being built at the Plasma Science and Fusion Center (PSFC) by Hare’s group is called: PUFFIN (PUlser For Fundamental (Plasma Physics) INvestigations).

In a pulsed-power facility, tiny cylindrical arrays of extremely thin metal wires usually generate the plasma. Varnish’s experiments use an array in which graphite leads, the kind used in mechanical pencils, replace the wires. “Doing so gives us the right kind of plasma with the right kind of properties we’d like to study,” Varnish says. The solution is also easy to work with and “not as fiddly as some other methods.” A thicker post in the middle completes the array. A pulsed current traveling down the array vaporizes the thin wires into a plasma. The interactions between the current flowing through the plasma and the generated magnetic field pushes the plasma radially outward. “Each little array is like a little exploding bubble of magnetized plasma,” Varnish says. He studies the interaction between the plasma flows at the center of two adjacent arrays.

Studying plasma behavior

The plasma generated in these pulsed-power experiments is stable only for a few hundred nanoseconds, so diagnostics have to take advantage of an extremely short sampling window. Laser interferometry, which images plasma density, is Varnish’s favorite. In this technique, a camera takes a picture of a split laser beam, one arm of which encounters the plasma and one that doesn’t. The arm that hits the plasma produces an interference pattern when the two arms are recombined. Capturing the result with a camera allows researchers to infer the structure of the plasma flows.

Another diagnostic method involves placing tiny loops of metal wire in the plasma (called B-dots), which record how the magnetic field in the plasma changes in time. Yet another way to study plasma physics is using a technique called Faraday rotation, which measures the twisting of polarized light as it passes through a magnetic field. The net result is an “image map of magnetic fields, which is really quite incredible,” Varnish says.

These diagnostic techniques help Varnish research magnetic reconnection, the process by which plasma breaks and reforms magnetic fields. It’s all about energy redistribution, Varnish says, and is particularly relevant because it creates solar flares. Varnish studies how having not-perfectly-opposite magnetic field lines might affect the reconnection process.

Most research in plasma physics can be neatly explained by the principles of magnetohydrodynamics, but the phenomena observed in Varnish’s experiments need to be explained with additional theories. Using pulsed power enables studies over longer length scales and time periods than in other experiments, such as laser-driven ones. Varnish is looking forward to working on simulations and follow-up experiments on PUFFIN to study these phenomena under slightly different conditions, which might shed new light on the processes.

At the moment, Varnish’s focus is on programming the control systems for PUFFIN so he can get it up and running. Part of the diagnostics system involves ensuring that the facility will deliver the plasma-inducing currents needed and perform as expected.

Aiding LGBTQ+ efforts

When not working on PUFFIN or his experiments, Varnish serves as co-lead of an LGBTQ+ affinity group at the PSFC, which he set up with a fellow doctoral student. The group offers a safe space for LGBTQ+ scientists and meets for lunch about once a month. “It’s been a nice bit of community building, and I think it’s important to support other LGBTQ+ scientists and make everyone feel welcome, even if it’s just in small ways,” Varnish says, “It has definitely helped me to feel more comfortable knowing there’s a handful of fellow LGBTQ+ scientists at the center.”

Varnish has his hobbies going. One of his go-to bakes is a “rocky road,” a British chocolate bar that mixes chocolate, marshmallows, and graham crackers. His research interests, too, are a delicious concoction mixed together: “the intersection of plasma physics, laboratory astrophysics, astrophysics (the won’t-fit-in-a-lab kind), and instrumentation.”
