Bionic flexible touch sense sensing array based on piezoresistive type and capacitance type combination

The invention discloses a bionic flexible touch sense sensing array based on piezoresistive type and capacitance type combination. The bionic flexible touch sense sensing array is successively composed of a flexible substrate layer, a capacitance layer, a piezoresistive layer and a surface packaging layer from bottom to top. The sensing array is simultaneously integrated with two types of touch sense force sensitive components based on the piezoresistive type and the capacitance type; a piezoresistive type force sensitive layer is overlaid on a capacitance-type force sensitive layer; the resolution of a piezoresistive layer space is 1mm; the resolution of a capacitance layer space is 2mm; a piezoresistive type force sensitive layer circuit is a matrix circuit; each node of the matrix circuit is provided with a semilunar electrode and a bar-shaped electrode; the two electrodes are connected by PDMS (Polydimethylsiloxane) conducting rubber; a capacitance-type force sensitive layer circuit is a matrix circuit; the lower layer of the matrix circuit forms a capacitance lower polar plate; the upper layer of the matrix circuit forms a capacitance upper polar plate; a PDMS dielectric layer with surface patterns is arranged between the two polar plates; the piezoresistive layer and the capacitance layer respectively measure static force and transient force; and the comprehensive performance of the bionic flexible touch sense sensing array can be improved.
