HIGHLY STRETCHABLE PIEZORESISTIVE WIRE SENSOR AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2019/212085

A1

The present invention relates to a highly stretchable piezoresistive wire sensor and a manufacturing method therefor, wherein the highly stretchable piezoresistive wire sensor is composed of: a conductive core, in which a silicon polymer is mixed with multi-walled carbon nanotubes (MWCNTs); and an insulating sheath of a silicone material, and is operable in the strain range of 10-500%. The highly stretchable piezoresistive wire sensor according to the present invention comprises: a conductive core (1) comprising a silicone polymer (platinum-catalyzed silicone), multi-walled carbon nanotubes (MWCNTs), and anhydrous toluene (99.8%); and an insulating sheath (2) of a silicone material covering the external surface of the conductive core (1).
