SkinSense Self-Powered Flexible Sensor Skin: Touch for Any Surface
FlexSense launched SkinSense, a self-powered sensor film just 0.3mm thick that sticks to any surface to detect pressure, temperature, and humidity. It harvests energy through triboelectric nanogeneration, requiring no battery, and is already in use for industrial monitoring and medical care.
Giving Everything a Sense of Touch — SkinSense Self-Powered Sensor Skin
One of the core challenges facing the Internet of Things is sensor power. Billions of sensors need batteries or wired connections, which severely limits large-scale deployment.
FlexSense's SkinSense tackles the problem with triboelectric nanogeneration technology. Released on April 30, the sensor film is just 0.3 millimeters thick and can be applied to any surface like a sticker. It harvests energy from micro-deformations and friction on the surface it's attached to — no battery required.
SkinSense detects three physical quantities: pressure (0.1 Pascal precision), temperature (0.1 degree Celsius precision), and humidity (1% precision). Data is transmitted via a built-in NFC chip to a smartphone or gateway.
In industrial monitoring, SkinSense is attached to pipe surfaces to detect subtle pressure fluctuations that signal leaks. In medical care, it's integrated into bandages to track temperature and humidity changes at wound sites.
SkinSense is priced at $2 per 10cm-by-10cm sheet and has already partnered with Siemens and 3M. FlexSense plans to expand applications into smart packaging and wearable health monitoring by 2031.
