DETAILED DESCRIPTION - Preparation of sensor based on single-side micro touch structure involves mixing polydimethylsiloxane (PDMS) elastomer and curing agent to obtain PDMS prepolymer, adding graphene prepolymer and stirring to obtain GPC ink, spin-coating the PDMS prepolymer layer on one side surface of film-forming steel plate provided with arc pit, pressing polyethylene terephthalate (PET) layer on the PDMS pre-polymer layer, stripping the steel plate to obtain PDMS substrate, coating the GPC ink on the upper surface of the indium tin oxide-PET layer (ITO-PET) to form GPC layer, pressing one side surface of the other PET layer on the GPC layer, heating and pouring the formed GPC layer, peeling off the PET layer to obtain sensing structure layer (A), coating the GPC ink on the upper surface of the ITO-PET layer to form GPC layer, pressing the frosted surface of the abrasive paper on the GPC layer, heating and pouring the formed GPC layer, peeling off the sand paper to obtain sensing structure layer (B), stacking the sensing structure layer (A), sensing structure layer (B) and the PDMS substrate sequentially from top to bottom to form composite sensing structure layer, which is used for contact sensing, and attaching polyimide (PI) adhesive tape to the edge of the composite sensing structure layer for encapsulation and fixation. The upper surface of the PDMS substrate forms strip-shaped convex structure corresponding to the arc pit. The surface of one side of the sensing structure layer (B) is formed with contact inner micro-structure corresponding to the sand paper. An INDEPENDENT CLAIM is included for sensor based on single-side micro-touch structure.
