Abstract

A sensor for sensing pressure is disclosed. The sensor may be a pressure sensor for sensing pressure, or a tactile sensor for sensing tactile events through pressure measurement. In one aspect, the sensor includes at least one pressure sensor having at least one VCSEL on a substrate. It further includes a compressible sensor layer covering a top surface of the at least one VCSEL, and a reflecting element covering a top surface of the sensor layer. A method of manufacturing such a sensor is also disclosed.
