AI chips could get a sense of time with memristor that can be tuned

Artificial neural networks may soon be able to process time-dependent information, such as audio and video data, more efficiently. The first memristor with a "relaxation time" that can be tuned is reported today in Nature Electronics, in a study led by the University of Michigan. Memristors, electrical components that store information in their electrical resistance, could reduce AI's energy needs by about a factor of 90 compared to today's graphical processing units. Already, AI is projected to account for about half a percent of the world's total electricity consumption in 2027, and that has the potential to balloon as more companies sell and use AI tools. "Right now, there's a lot of interest in AI, but to process bigger and more interesting data, the approach is to increase the network size. That's not very efficient," said Wei Lu, the James R. Mellor Professor of Engineering at U-M and co-corresponding author of the study with John Heron, U-M associate professor of materials science and engineering.

Researchers develop thin film as resistance-switching material for next-generation memristive devices

Memristive devices are capable of retaining their internal resistance, thus offering superior performance compared to conventional devices that use integrated circuits. Several materials have been explored for the manufacture of these devices. In recent years, transition metal oxides have gradually become widely popular for this purpose. Due to their increasing application in diverse domains like artificial intelligence systems, memristive devices must now overcome several issues related to data retention, endurance, and a large number of conductance states. Moreover, the individual fabrication of these devices is time-consuming. As a result, several challenges need to be addressed to improve their performance and reliability. In a recent study led by Professor Min Kyu Yang from Sahmyook University, Korea, researchers have developed a silver (Ag)-dispersive chalcogenide thin film for use as a resistance-switching material in memristive devices. Their paper is published in the journal Applied Surface Science.

MIT Engineers Develop Groundbreaking Microscale Battery for Autonomous Robotics

New Post has been published on https://thedigitalinsider.com/mit-engineers-develop-groundbreaking-microscale-battery-for-autonomous-robotics/

MIT Engineers Develop Groundbreaking Microscale Battery for Autonomous Robotics

The field of microscale robotics has long grappled with a fundamental challenge: how to provide sufficient power to autonomous devices small enough to navigate within the human body or industrial pipelines. Traditional power sources have been too large or inefficient for such applications, limiting the potential of these miniature marvels. However, a groundbreaking development from the Massachusetts Institute of Technology (MIT) promises to overcome this hurdle, potentially ushering in a new era of microscale robotics.

Engineers at MIT have designed a battery so small it rivals the thickness of a human hair, yet powerful enough to energize autonomous micro-robots. This innovation could transform fields ranging from healthcare to industrial maintenance, offering unprecedented possibilities for targeted interventions and inspections in previously inaccessible environments.

The Power of Miniaturization

The new MIT-developed battery pushes the boundaries of miniaturization to remarkable extremes. Measuring just 0.1 millimeters in length and 0.002 millimeters in thickness, this power source is barely visible to the naked eye. Despite its minuscule size, the battery packs a considerable punch, capable of generating up to 1 volt of electricity—sufficient to power small circuits, sensors, or actuators.

The key to this battery’s functionality lies in its innovative design. It harnesses oxygen from the surrounding air to oxidize zinc, creating an electrical current. This approach allows the battery to function in various environments without the need for external fuel sources, a crucial factor for autonomous operation in diverse settings.

Compared to existing power solutions for tiny robots, the MIT battery represents a significant leap forward. Previous attempts to power microscale devices often relied on external energy sources, such as lasers or electromagnetic fields. While effective in controlled environments, these methods severely limited the robots’ range and autonomy. The new battery, in contrast, provides an internal power source, greatly expanding the potential applications and operational scope of micro-robots.

Unleashing Autonomous Micro-Robots

The development of this microscale battery marks a pivotal shift in the field of robotics, particularly in the realm of autonomous micro-devices. By integrating a power source directly into these tiny machines, researchers can now envision truly independent robotic systems capable of operating in complex, real-world environments.

This enhanced autonomy stands in stark contrast to what researchers refer to as “marionette” systems—micro-robots that depend on external power sources and control mechanisms. While such systems have demonstrated impressive capabilities, their reliance on external inputs limits their potential applications, particularly in hard-to-reach or sensitive environments.

Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT and senior author of the study, emphasizes the transformative potential of this technology: “We think this is going to be very enabling for robotics. We’re building robotic functions onto the battery and starting to put these components together into devices.”

The ability to power various components, including actuators, memristors, clock circuits, and sensors, opens up a wide array of possibilities for these micro-robots. They could potentially navigate through complex environments, process information, keep track of time, and respond to chemical stimuli—all within a form factor small enough to be introduced into the human body or industrial systems.

Potential Applications

From healthcare to industrial maintenance, the potential applications of this technology are as diverse as they are groundbreaking.

Medical Frontiers

The microscale battery technology opens up exciting possibilities in the medical field, particularly in targeted drug delivery. Researchers envision deploying tiny, battery-powered robots within the human body to transport and release medications at specific sites. This approach could revolutionize treatments for various conditions, potentially improving efficacy while reducing side effects associated with systemic drug administration.

Beyond drug delivery, these micro-robots could enable new forms of minimally invasive diagnostics and interventions. For instance, they might be used to collect tissue samples, clear blockages in blood vessels, or provide real-time monitoring of internal organs. The ability to power sensors and transmitters at this scale could also lead to advanced implantable medical devices for continuous health monitoring.

Industrial Innovations

In the industrial sector, the applications of this technology are equally promising. One of the most immediate potential uses is in gas pipeline leak detection. Miniature robots powered by these batteries could navigate through complex pipeline systems, identifying and locating leaks with unprecedented precision and efficiency.

The technology could also find applications in other industrial settings where access is limited or dangerous for humans. Examples include inspecting the integrity of structures in nuclear power plants, monitoring chemical processes in sealed reactors, or exploring narrow spaces in manufacturing equipment for maintenance purposes.

Inside the Micro-Battery

The heart of this innovation is a zinc-air battery design. It consists of a zinc electrode connected to a platinum electrode, both embedded in a polymer strip made of SU-8, a material commonly used in microelectronics. When exposed to oxygen molecules in the air, the zinc oxidizes, releasing electrons that flow to the platinum electrode, thus generating an electric current.

This ingenious design allows the battery to power various components essential for micro-robotic functionality. In their research, the MIT team demonstrated that the battery could energize:

An actuator (a robotic arm capable of raising and lowering)

A memristor (an electrical component that can store memories by changing its electrical resistance)

A clock circuit (enabling robots to track time)

Two types of chemical sensors (one made from atomically thin molybdenum disulfide and another from carbon nanotubes)

Future Directions and Challenges

While the current capabilities of the micro-battery are impressive, ongoing research aims to increase its voltage output, which could enable additional applications and more complex functionalities. The team is also working on integrating the battery directly into robotic devices, moving beyond the current setup where the battery is connected to external components via a wire.

A critical consideration for medical applications is biocompatibility and safety. The researchers envision developing versions of these devices using materials that would safely degrade within the body once their task is complete. This approach would eliminate the need for retrieval and reduce the risk of long-term complications.

Another exciting direction is the potential integration of these micro-batteries into more complex robotic systems. This could lead to swarms of coordinated micro-robots capable of tackling larger-scale tasks or providing more comprehensive monitoring and intervention capabilities.

The Bottom Line

MIT’s microscale battery represents a significant leap forward in the field of autonomous robotics. By providing a viable power source for cell-sized robots, this technology paves the way for groundbreaking applications in medicine, industry, and beyond. As research continues to refine and expand upon this innovation, we stand on the brink of a new era in nanotechnology, one that promises to transform our ability to interact with and manipulate the world at the microscale.

MIT engineers design tiny batteries for powering cell-sized robots

MIT engineers design tiny batteries for powering cell-sized robots

A tiny battery designed by MIT engineers could enable the deployment of cell-sized, autonomous robots for drug delivery within in the human body, as well as other applications such as locating leaks in gas pipelines.

The new battery, which is 0.1 millimeters long and 0.002 millimeters thick — roughly the thickness of a human hair — can capture oxygen from air and use it to oxidize zinc, creating a current of up to 1 volt. That is enough to power a small circuit, sensor, or actuator, the researchers showed.

“We think this is going to be very enabling for robotics,” says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT and the senior author of the study. “We’re building robotic functions onto the battery and starting to put these components together into devices.”

Ge Zhang PhD ’22 and Sungyun Yang, an MIT graduate student, are the lead author of the paper, which appears in Science Robotics.

Powered by batteries

For several years, Strano’s lab has been working on tiny robots that can sense and respond to stimuli in their environment. One of the major challenges in developing such tiny robots is making sure that they have enough power.

Other researchers have shown that they can power microscale devices using solar power, but the limitation to that approach is that the robots must have a laser or another light source pointed at them at all times. Such devices are known as “marionettes” because they are controlled by an external power source. Putting a power source such as a battery inside these tiny devices could free them to roam much farther.

“The marionette systems don’t really need a battery because they’re getting all the energy they need from outside,” Strano says. “But if you want a small robot to be able to get into spaces that you couldn’t access otherwise, it needs to have a greater level of autonomy. A battery is essential for something that’s not going to be tethered to the outside world.”

To create robots that could become more autonomous, Strano’s lab decided to use a type of battery known as a zinc-air battery. These batteries, which have a longer lifespan than many other types of batteries due to their high energy density, are often used in hearing aids.

The battery that they designed consists of a zinc electrode connected to a platinum electrode, embedded into a strip of a polymer called SU-8, which is commonly used for microelectronics. When these electrodes interact with oxygen molecules from the air, the zinc becomes oxidized and releases electrons that flow to the platinum electrode, creating a current.

In this study, the researchers showed that this battery could provide enough energy to power an actuator — in this case, a robotic arm that can be raised and lowered. The battery could also power a memristor, an electrical component that can store memories of events by changing its electrical resistance, and a clock circuit, which allows robotic devices to keep track of time.

The battery also provides enough power to run two different types of sensors that change their electrical resistance when they encounter chemicals in the environment. One of the sensors is made from atomically thin molybdenum disulfide and the other from carbon nanotubes.

“We’re making the basic building blocks in order to build up functions at the cellular level,” Strano says.

Robotic swarms

In this study, the researchers used a wire to connect their battery to an external device, but in future work they plan to build robots in which the battery is incorporated into a device.

“This is going to form the core of a lot of our robotic efforts,” Strano says. “You can build a robot around an energy source, sort of like you can build an electric car around the battery.”

One of those efforts revolves around designing tiny robots that could be injected into the human body, where they could seek out a target site and then release a drug such as insulin. For use in the human body, the researchers envision that the devices would be made of biocompatible materials that would break apart once they were no longer needed.

The researchers are also working on increasing the voltage of the battery, which may enable additional applications.

The research was funded by the U.S. Army Research Office, the U.S. Department of Energy, the National Science Foundation, and a MathWorks Engineering Fellowship.
