This device is a sheet-like device with many thin layers. The layer that comes into contact with the skin is an elastic rubber-like polymer layer that fits the curved surface of human skin. Next to the layer that comes into contact with the skin is an electronic device and a silicon layer that fixes the electronic device. Next to the silicon layer is a breathable fabric layer. This fabric layer covers the electronics and plays a role in protecting the electronics from impact.
The layer that actually gives tactile sensation is made of
The actuator is driven by
The research team has already created a prototype of a sheet-like device with a size of 15cm x 15cm. I connected the touch screen interface to the sheet-like device, traced the touch screen and sent the shape pattern `` X '', and confirmed that the stimulus of the shape of `` X '' was transmitted in synchronization with the finger tracing the touch screen That. The actual prototype is below.
When you bend, you can see the presence of the actuator inside.
In addition to the usages such as “VR game that conveys tactile sensation when touching the screen and the other party touching the screen,” “Tactile sensation is transmitted to this side.” The research team has devised a usage such as ” People with prosthetic limbs have the problem that “the power put in the prosthetic limbs is not known and it is difficult to adjust the power”. If this device can sense the pressure applied to the prosthesis at other parts, it will be easier to adjust the force.
The research team is not only working on making sheet-like devices thinner and lighter, but also plans to work on transmitting “heat” in addition to touch.
