TakkTile turns digital barometers into open-source robot touch sensors

Engadget writes, Freescale Semiconductor's MPL115A2 is a tiny thing that will sit quite comfortably on the tip of your finger. It's hard not to marvel at the engineering that went into the creation of something so small, yet so sensitive. The little metal square is minute enough to be plunked into a cell phone, offering up location pinpointing technologies that supplement GPS, gauging positions based on changes in atmospheric pressure. Harvard's Biorobotics team was clearly impressed when it discovered the technology, devising a fascinating implementation that extends beyond the walls of the cell phone. The...
