A radiowave (green) in an opto-electro-mechanical converter makes a micromembrane vibrate via electrostatic forces. The vibration is measured with a laser beam reflected off the membrane and interfering with itself. This technique allows the detection of very faint radiowaves. Photo: Anders Simonsen, NBI.
