Yesterday [Cypress Semiconductor](http://www.cypress.com/capsense) (NYSE: CY) unveiled a new version of its CapSense Express technology to replace touch-sensitive buttons and sliders on mobile devices.
The company says its buttons and controls are more durable than competing mechanical devices and have proven resistant to temperature and environmental elements.
Hadn’t thought about having to change the buttons on a keypad, but nice to know the technology exists! The company sells the replacement parts in Programmable System-on-Chip (PSoC) kits.
