Piezoresistive sensors, which change electrical resistance when compressed, offer a simpler reatout mechanism. Conductive fillers like carbon nanotubes, graphane, or silver nanowires are dispersed in a flexible ble polymer matrix.

Temperature sensing in biomimetic skin is typically accered using materials with a high temperatur coefficient of resistance (TCR), such as platinum, gold, or carbon-based composites. By embedding thin- film thermistors or termocouple in a flexible ble substrate, the sensor can menure local temperatur changes with precision.
