a The performance of a SnS2 based strain sensor working under illumination when detecting vibrations induced by sound in comparison to signal when working in darkness. b Schematic of strain points produced by motion of a human body used for strain detection by SnS2 based devices. c The measured response produced by smile motion for sensor mounted on cheek, as shown in insert. d Response to wrist bending following positions shown below. e Sensor response to motion of standing and sitting corresponding to the insert image for sensor fixed on knee. f Signals from sensor on knee showing comparative response for slow and rapid walking.
