Microchip enhances touch sensing tech

18 August 2010 Analogue, Mixed Signal, LSI

Microchip has developed technology which enables capacitive touch-sensing with a metal front panel. Building upon the success of the initial release of mTouch capacitive touch-sensing technology, the technology now works through metal, gloves and on surfaces that contain liquids, and it enables Braille to be used on capacitive touch-sensing interfaces. Designers can integrate mTouch capacitive touch-sensing functionality with their existing application code in an 8-, 16- or 32-bit PIC microcontroller (MCU).

Major applications for mTouch capacitive touch-sensing user interfaces include those in the appliance market, because of the possibility of a stainless-steel front panel; the industrial market, because of the technology’s robustness and the automotive market, because of the technology’s sleek aesthetics. Low-power mTouch capacitive touch-sensing technology features an active current of less than 5 μA.
