The clumsy robot era is almost over, and the University of California engineers have recently created an ultra-thin interactive sensor electronic skin that can be decorated on the surface of any object. It instantly illuminates when it is touched, and the greater the pressure, the brighter the light it emits. This result is expected to give the robot a more realistic touch.
Humans need to activate a large part of the sports cortex when controlling their own hands, using subtle balance to achieve a variety of feedback. Previously, in the field of robotics, how to improve the flexibility and extensibility of the body has plagued researchers, and making the robot more sensitive to touch has proved to be a very difficult challenge.
The interactive pressure sensor skin created by the engineers responded immediately when touched. Compared with the rigid iPhone touch screen, this system is very flexible. No matter how complicated the geometric surface, you can press it. The surface, so this technology is also expected to add a more intuitive human-machine interface to the mobile phone, game console controller, so that people's actions and sensor-mounted devices to achieve better interaction.
Skin production is relatively simple, depositing a thin layer of polymer on a silicon chip and then stacking a layer of transistors, an organic LED, and a pressure sensor using standard semiconductor fabrication techniques. Finally, when finished, the layer of plastic on the silicon substrate was peeled off, leaving a clean film with a built-in sensor network.
The end result is a 16*16 matrix sensor that responds quickly within a millisecond. The entire electronic component of the skin is vertically integrated. The seemingly inexpensive plastic block has a complex system built in. The inventor of the skin also said that in the future, it is hoped to create a more advanced sensor skin, hoping for temperature. And the light also produces a sharp feedback.
