Touch sensor with integrated antenna

摘要

In one embodiment, an apparatus includes one or more flexible substrates having flexible conductive material disposed thereon and a radiating element disposed on a first region of the flexible substrates. The radiating element includes a first portion of the flexible conductive material. The apparatus includes a touch-sensing area disposed on a second region of the flexible substrates. The touch-sensing area includes multiple electrodes that each include a respective second portion of the flexible conductive material disposed on the flexible substrates. The electrodes are configured to sense touch of an object at the touch-sensing area.
