The world’s smallest accelerometer created with graphene

A group of researchers at the KTH Royal Institute of Technology has created what was defined as the world’s smallest accelerometer, a device that could revolutionize the wearable device compartment or that of video games.

The researchers used the nano material of the moment, graphene, to create the transducer, which can also be manufactured at low cost. It is an ultra-small accelerometer defined by Xuge Fan, a researcher at the Department of Micro and Nanosystems of KTH, “the smallest electromechanical accelerometer in the world” made thanks to the possibility of using thick components on an atomic scale such as those made of graphene.

The researchers have created a piezo-resistant NEMS (nano-electromechanical systems) accelerometer that, despite being very small, maintains the level of sensitivity required by these devices with a size measurable in a few millimeters for a device at least two orders of magnitude smaller than conventional accelerometers made with silicon, even the most advanced.

What are the possible uses? Monitoring systems for cardiovascular diseases as well as devices for the acquisition of data on ultra-sensitive and portable motion, able to monitor even the smallest movements of the human body, video game peripherals, resonators, gyroscopes and microphones.
