Abstract

A multi-sensing system, a portable electronic device, and a touch-sensing method are provided. The multi-sensing system includes a sensing sheet and a carrier. The sensing sheet includes a substrate, and a touch-sensing circuit and a force-sensing circuit disposed on the substrate, wherein an orthogonal projection of the force-sensing circuit on the substrate and an orthogonal projection of the touch-sensing circuit on the substrate are misaligned from each other. The carrier has a carrying space and a carrying shoulder adjacent to the carrying space, wherein the carrier carries the sensing sheet with the carrying shoulder. The carrying space is used to accommodate a display element. The touch-sensing circuit is located above the display element.
