Abstract: A resistive touch sensor includes a base layer, a sensor top sheet positioned in spaced apart relation to a base layer, and a peripheral edge seal formed between the sensor top sheet and the base layer. The sensor further includes a first adhesive layer bonded on a peripheral edge portion to the sensor top sheet, and a second adhesive layer, inset relative to the peripheral edge seal, positioned between the first adhesive layer and the sensor top sheet.

Abstract: Device and method for biometric recognition are provided. When first touch surface and second touch surface are in folded state, if it is determined that first touch surface faces current user, since sensing unit is provided under first touch surface, first touch surface can directly capture first contact information of user. When it is determined that second touch surface is facing current user, processing unit projects the touch recognition area and the second touch part that is currently in contact with first touch surface onto second touch surface correspondingly, user can move second touch part so that virtual second touch part on second touch surface is within virtual touch recognition area. Thus, touch recognition area of first touch surface which is facing away from user can obtain second contact information. Problems such as inconvenience of multi-fingerprint fingerprint operation of under-screen fingerprint recognition device after folding are solved.
