This Video is About Electroadhesion.

How would you stick a slice of banana to a sheet of copper? Until a few months ago, you couldn’t. But a new discovery called “hard-soft electroadhesion” enables chemists to stick almost any hydrogel to almost any metal, using nothing but an electric current. Join George as he tries to replicate electroadhesion in his basement and discovers what it has in common with superglue… and, surprisingly, water.

Gluing soft materials without glue

Share: advertisement FULL STORY If you’re a fan of arts and crafts, you’re likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers reporting in ACS Applied Materials & Interfaces now have a brand-new way to weld squishy stuff together without the need for glue at all. They’ve demonstrated a universal, “electroadhesion” technique that can adhere soft materials to each other just by running electricity through them. There’s a glue out there for almost any situation, whether it involves plastic, fabric, wood or beyond. But things get a bit tricky when materials are soft and squishy, like tissues or engineered organs. Strategies including 3D-printing avoid glues altogether by fusing together an entire structure — such as an organ — all at once. But this can be slow and laborious, and require advanced technical equipment. Another alternative could be electroadhesion, in which an electric field is used to hold oppositely charged materials together, forming attachments between the materials’ components. This can involve chemical bonds, like ionic bonds, or more physical connections, like ensnaring polymer chains together. Plus, it works with little more than a household battery and pencil lead. Previously, Srinivasa Raghavan and colleagues showed that electroadhesion could reversibly hold a gel to a tissue without the need for sutures. But now, they wanted to see if the technique could work for any two materials, given that they had opposite charges, to precisely and reversibly hold them together. To explore the phenomenon, the team tested a gel in addition to three types of capsules made of alginate or chitosan — both naturally occurring polymers — that were either positively or negatively charged. When attached to graphite electrodes and exposed to a 10-V electric field for around 10 seconds, the oppositely charged materials stuck together. This bond was strong enough to withstand gravity, and evidence from previous experiments suggests it could last for years. By reversing the flow of electricity, however, the bond was easily broken. The team assembled chains and even 3D cubes out of individual, spherical capsules. The researchers also used electroadhesion to sort capsules by their charges, either by laying a charged gel on top of several capsules, or by touching them with a fingertip “robot” that adhered the capsules to themselves. The researchers say that this work demonstrates the universality of electroadhesion and could one day be used in robotics and tissue engineering.

HAMR-E – Harvard Ambulatory Micro-Robot with Electroadhesion, by Sébastien D. de Rivaz et al (2018), Hansjörg Wyss Institute for Biologically Inspired Engineering, Harvard University. This tiny (1.48 gram) quadrupedal micro-robot can climb conductive surfaces using high-voltage to generate an electrostatic force between the foot pads and the surface. It was developed in conjunction with Rolls-Royce with the idea of inspecting the interior of jet engines without the expense of dismantling them.

Researchers have created a micro-robot whose electroadhesive foot pads, inspired by the pads on a gecko's feet, allow it to climb on vertical and upside-down conductive surfaces, like the inside walls of a commercial jet engine. Groups of them could one day be used to inspect complicated machinery and detect safety issues sooner, while reducing

The Gecko autonomous devices are wall climbing robots equipped with a spectrum of wall adhesion technologies to adapt to any potential vertical obstacle. Embedded in each of its 16 pads are electroadhesion generators, pneumatic (suction) machines, centrifugal (air blowing devices that can temporarily transform the Gecko into a flying robot), multiple microspines and a variety of sensors ranging from x-ray to ultrasound.. A wall may be slippery, rough, smooth or rocky but the Gecko will have no problem in traversing it. The tail component is removable and can be replaced with a variety of devices depending on its mission. The tail can be equipped with sensors that can assess a wall’s integrity, a paint blower or 3D printer that can change a building’s façade, or spying devices with exotic weaponry.

You don't need glue to hold these materials together—just electricity

Is there a way to stick hard and soft materials together without any tape, glue or epoxy? A new study published in ACS Central Science shows that applying a small voltage to certain objects forms chemical bonds that securely link the objects together. Reversing the direction of electron flow easily separates the two materials. This electroadhesion effect could help create biohybrid robots, improve biomedical implants and enable new battery technologies. When an adhesive is used to attach two things, it binds the surfaces either through mechanical or electrostatic forces. But sometimes those attractions or bonds are difficult, if not impossible, to undo. As an alternative, reversible adhesion methods are being explored, including electroadhesion (EA). Though the term is used to describe a few different phenomena, one definition involves running an electric current through two materials causing them to stick together, thanks to attractions or chemical bonds. Previously, Srinivasa Raghavan and colleagues demonstrated that EA can hold soft, oppositely charged materials together, and even be used to build simple structures. This time, they wanted to see if EA could reversibly bind a hard material, such as graphite, to a soft material, such as animal tissue.

Special series: the path untrodden part three⠀ ⠀ Follow along as Lyra Wanzer, S.B. ‘19, concentrating in mechanical engineering, builds an electroadhesive treaded robot for her senior capstone project⠀ ⠀ After many iterations on the tread design throughout the semester, Wanzer ultimately used a design with multiple layers. In our most recent update with Wanzer, she was working through different prototypes of the drive system alignment that connected the treads of her robot. In her final product, she has added end caps to prevent the wheels from sliding sideways and optimized the length of couplings between the wheels to secure the drive system. She made carbon fiber bushings, bearings to reduce friction between different parts of the car. She constructed the wheels of the robot from two layers of compliant foam. Wanzer tried both a concave and a convex tread and found that a convex tread worked best for her robot.⠀ ⠀ In the final stages of building her robot, Wanzer evaluated the total mass of the robot, the wheel torque, the voltages, and safety. She added a top plate to make the chassis, the base frame, rigid to protect the robot during testing. Then she studied the speed of the robot while it pulled a load of varying mass behind it to optimize her system. As the angle of the inclined surface increased, the speed of her robot decreased. Moving on a 30 degree incline, her robot was much faster than other existing electroadhesive robots.⠀ ⠀ In the future, she would like to see further work done in making the robot lighter and better able to hold a greater load. Wanzer intends to publish her work to share her design with the robotics community. Grateful for the mentorship she received from her lab, the course staff, and the @seasallabs , Wanzer speaks highly of the learning experience of the capstone project. Like her robot, she looks forward to exploring new ground and embarking on the next steps of her journey in robotics.⠀ #HarvardSEAS #LifeatSEAS #Harvard19 #student #robot #project (at Harvard John A.
