A San Jose, California startup called Ultrasense has plans to turn any surface into a touchscreen. The company has created a new type of sensor smaller than the size of a ballpoint pen tip that can sense touch using 3D ultrasound technology. The “TouchPoint” sensor detects how tiny sound waves are moving through a given surface, as well as, discern between different kinds of touches.
Being a system-on-chip (SoC), the TouchPoint sensor has all its necessary computing and electronic components built into it, which makes it incredibly small, efficient, and according to Ultrasense doesn’t put a strain on the system’s main CPU.
This type of sensor opens up the potential for innovation in almost any kind of product. Now designers will be able to develop products with unique features and capabilities.
