As the adoption of tiny machines becomes widespread in diverse markets from healthcare to defence, the next logical step is further miniaturization. Nanoelectromechanical systems (NEMS) show great promise in many applications such as ultrasensitive sensors and components for radio frequency communication systems. But so far, their performance has been limited due to the use of heavy and thick metal electrodes that dampen the vibration of resonators.
To overcome this issue, academics in the USA have developed nano-resonators that utilise graphene as an ultra-thin, ultra-light electrode. The researchers have observed a striking increase in device performance, including greater detection speeds, higher sensitivity and greater limits of detection. The team is looking to engage in conversation with businesses around licensing and/or co-developing their technology.
