Abstract

Feel the dielectric force When a non-uniform electric field is applied to a nonconducting material, that material experiences a force. This can be seen in the macroscopic world, for instance when a stream of water from a running tap is deflected by a comb charged with static electricity. Unterreithmeier et al. have exploited this phenomenon — known as the dielectric force — to provide a simple and rapid means of electrically controlling the vibrational properties of tiny mechanical elements on a chip. And, applying the principle in reverse, they use it to detect the motion of these elements. Nanoelectromechanical systems (or NEMS) of this type are being widely investigated for applications as diverse as sensing and signal processing, for which efficient driving and detection schemes are vital.
