iSoft: A Customizable Soft Sensor with Real-time Continuous Contact and Stretching Sensing

on YouTube ↗19m

" summary

A soft, single-volume sensor built from carbon-filled silicone uses electrical impedance tomography with a 16-channel multiplexer, <0.5 mA drive and >50 Hz sampling to deliver real-time continuous touch and unidirectional stretch sensing. A dynamic baseline update plus a capacitive channel detects contact and movement to overcome hysteresis. Electronics cost ~ $30; fabrication cures in ~140 s with a heat press. Discrete targeting hits 96% accuracy, localization error is 4–7.5 mm (16 electrodes), stroke end error ~8.7 mm, stretch up to 40% adds ~1.1 mm error. A customization toolkit generates electrode guides for instant, personalized sensors.
