Specifications
Using an internal web of fiber-optic strain gauges (produced under license from the Canadian Space Agency), the MTC Express senses multiple points of pressure applied to its surface simultaneously. Each contact point sensed by the pad provides its data, consisting of x, y, and pressure values, at a sampling rate of 200 Hz.
