Actuators get tuned on the nanoscale

A nanomechanical resonator that converts electrical energy into mechanical strain using a highly efficient, tuneable actuation mechanism based on the piezoelectric effect has been developed by researchers in the US. The mechanism, which is radically different to that employed in previous nanoelectromechanical systems (NEMS), could find use in a variety of applications, including nanomechanical arrays for chemicals sensing, high-speed switches and nanomechanical logic-based computation.
