Engineers at the University of Houston have developed a flexible, easy-to-manufacture electronic patch that, when attached to the human body, directs human motion and other commands to the robot and receives temperature feedback from the robot.

Compared with Max, who has not figured out the human brain mechanism and is ready to open your brain, engineers from the University of Houston prefer to use a multi-functional HMI device ——Wearable patches make the integration of humans and machines easier.

The research results were published not long ago.Science Advances magazine.

This wearable patch is only less than 4 microns thick and uses only one material for the entire structure, but includes transistors, RRAM memory cells, strain sensors, UV detectors, temperature sensors and heaters.

What kind of magic patch is this?

One stick control arm, two stick machine heat feedback

Volunteers participating in the study applied a wearable patch on the back of the hand, and the muscle signal was directly used to guide the robot by capturing the movement of the human hand.

In order to better control the movement of the robot, the robot can also come up with such a <; a paste & rdquo;.

In this way, the integrated control circuit of the patch can be used to provide temperature feedback from the robot hand to the human hand to close the human-machine control loop.

It can be seen that the temperature of the white frame area rises significantly when the two hands are held together, and the temperature quickly returns to the body temperature after being released.

Through such a mechanism, the patch enables two-way communication between the machine and the person.

Compared with the brain-computer interface, although it is not possible to directly control the robot through consciousness, at least it does not have to face huge unknown risks.

Looks like instant noodles, hidden inside

At first glance, this 4 micron thick patch is nothing special, and it is even reminiscent of the necessary instant noodles in the fat house, but this small body is hidden under the small body.

When we zoomed in, we found out that the shape of each noodle is different. Each different form actually corresponds to a component.

From left to right are RRAM, FET, UV sensor, temperature sensor and strain sensor.

These devices are structures patterned by researchers using photolithography, consisting of 50 nm thick gold conductors, indium zinc oxide (IZO) semiconductors, polyimide packages, and (for transistors) common dielectric epoxy SU -8 composition.

The bubble shape of the conductor allows the device to stretch with the polyamide without breaking, so that the soft texture allows a person to get a better feel when wearing.

Revolutionary innovation, prospects can be expected

As Dr. Yu Cunjiang, the leader of the study, said: “Traditionally, to achieve multiple functions, you may need to integrate multiple materials or multiple chips. But now you can do it all with one material. ”

Dr. Yu Cunjiang, who achieved this innovation, will be listed on the MIT Science and Technology Review's “35 Innovative 35 People” list, which won the title of Pioneer.

The list aims to select the 35 youngest technology innovators or entrepreneurs who are considered to be the most talented, innovative, and most likely to change the world.

The winner was the invention of a stretchable rubber semiconductor material, and on this basis, various all-rubber electronic transistors, sensors, integrated devices and systems were developed, adding "stretching" to semiconductor materials. This performance, which has not been realized for many years, will also revolutionize the driving force in many fields.

We have reason to believe that this technology will better change our lives in the future.
