Abstract

Smart Prosthetics For prosthetics to be as natural and functional as possible, they need to replace lost sensing. Wu et al. developed a small, scalable sensor that converts applied pressure into pulses of corresponding frequency, conveying information in a way our brains can understand. Shaped like a tiny, flexible, hollow hockey puck, the sensor measures the change in magnetic impedance when the top of the puck is pressed. The sensor has a low detection limit and high sensitivity and shows stable-frequency pulse generation at a pressure lower than the sensing threshold of human skin. Sci. Robot. 3 , eaat0429 (2018).
