Microchip Develops mTouch Inductive Touch-Sensing Technology

Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced the general availability of the mTouch[tm] Inductive Touch-Sensing Technology, as an addition to its capacitive touch-sensing solutions. Inductive touch sensing’s fundamental operating principles enable it to work through a front panel such as plastic, stainless steel or aluminum. The technology also works through gloves and on surfaces that contain liquids. With the new technology, Microchip enables designers to integrate inductive touch-sensing functionality with their existing application code in a single standard 8-, 16- or 32-bit PIC® microcontroller (MCU) or 16-bit dsPIC® Digital Signal Controller (DSC), thus reducing total system costs. The technology implementation information is available for download, now from the Microchip Touch Sensing Design Center.

Microchip mTouch Inductive Touch-Sensing SolutionsTouch sensing continues to gain traction as an alternative to traditional push-button user interfaces, which improves reliability and lowers total system costs. Touch sensing also enables a completely sealed and modern-looking design. Major applications for inductive 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 and ability to reduce accidental touch triggers.

“Microchip continues to make it easy, inexpensive and royalty-free for engineers to implement touch-sensing interfaces into their designs,” said Steve Drehobl, vice president of Microchip’s Security, Microcontroller and Technology Development Division. “With the addition of inductive touch technology, we now give designers even more flexibility to choose the best touch-sensing technology for their application.”
