Light micrograph of a MEMS (MicroElectroMechanical System) microphone, installed in nearly all modern smartphones. The image shows the MEMS microphone with disassembled housing to show the wafer components inside. The left wafer is an amplifier to make the signals recordable for the smartphone electronics, the right wafer is the MEMS unit to receive acoustic waves. Microscopic contrast technique: Incident darkfield together with incident brightfield. Magnification: 40x when printed 10 centimetres wide.
