All-in-one piezoresistive-sensing patch integrated with micro-supercapacitor

An all-in-one sensing patch is integrated with piezoresistance sensor and micro-supercapacitor based on the porous CNT-PDMS elastomers. The porous CNT-PDMS elastomer is synthesized with solution-evaporation method, which could be modulated by the sugar templates and content ratio. Such piezoresistance-sensing patch could be utilized as 3D touch in user identification and safety communication through parameter extraction and signal decoding. Packaged into the sensing matrix, it shows feasibility in spatially mapping resolved pressure information about static pressure sensing and dynamic tactile trajectory.277
