Beschreibung
Zusammenfassung:	The invention discloses a flexible sensing device based on a laser direct-sketching biomass/thermoplastic elastomer composite material and a preparation method of the flexible sensing device. The preparation method comprises the following steps: mixing a biomass material, a compatibilizer, a carbon-forming agent and a thermoplastic elastomer, mixing at the temperature of 80-180 DEG C, and carrying out hot press molding to obtain a biomass/thermoplastic elastomer composite material film; the method comprises the following steps: pre-stretching an elastomer composite material film, then carrying out laser direct writing, recovering pre-stretching after laser direct writing, preparing a flexible circuit on the surface of the composite material, and packaging to obtain the flexible sensing device. According to the invention, biomass which is cheap and easy to obtain is taken as a filler and is fully mixed with the thermoplastic elastomer, so that on one hand, the production cost of the flexible sensing device is
