Abstract
Systems, methods, and computer-readable media are disclosed for capacitive touch sensing using system-in-package components and batteries. In one embodiment, a device may include a flexible printed circuit, a button cell electrically coupled to the flexible printed circuit, and a system-in-package that is electrically coupled to the flexible printed circuit. The system-in-package may include an electromagnetic interference shield, and a capacitive touch sensor. The capacitive touch sensor may be configured to detect a change in capacitance via a change in electric field at the electromagnetic interference shield.
