Beschreibung
Zusammenfassung:	The invention discloses a touch sensor based on liquid metal, an array and a preparation method thereof, and belongs to the technical field of sensing. The touch sensor comprises: an upper layer elastomer and a lower layer elastomer, wherein the upper layer elastomer and the lower layer elastomer are adhered to form a micro-channel, the micro-channel comprises 2N sections of sub-micro-channels, and the adjacent sub-micro-channels are communicated with each other and are vertically arranged; a liquid metal, wherein the micro-channel is filled with the liquid metal; and 2N + 1 conducting wires leading out from the two ends and the middle of the micro-channel at equal intervals and connected to data acquisition equipment so as to simultaneously measure the strain in two directions which are perpendicular to each other. By detecting the voltage change of the liquid metal in each sub-micro-channel, the deformation of the tactile sensor and the position and size of the contact force can be obtained, so that the tou
