Inductive sensing
Infineon's Flyback based inductive sensing is a new and proprietary technology which allows developer to create new HMI applications, such as touch-over-metal, force touch surfaces and proximity sensing. It is less sensitive to noise and more robust than current state of the art approaches that suffer from external noise as well as manufacturability concerns.
Inductive sensing on PSOC™ 4 technology is highly complementary to capacitive sensing and enables modern, metal-based and waterproof designs with sleek form factors such as metal touch buttons on refrigerators or robust HMI for underwater devices such as cameras and wearables.
