Engineer creates new design for ultra-thin capacitive sensors

As part of ongoing acoustic research at Binghamton University, Distinguished Professor Ron Miles has created a workable sensor with the least possible resistance to motion. The thin and flexible sensor is ideal for sensing sounds because it can move with the airflow made by even the softest noises and addresses issues with accelerometers, microphones and many other similar sensors.

“The goal was to create a sensor that only resists gravity,” explained Miles. “The sensor needed to stay connected to the device but other than that, I wanted it to move with even the slightest sounds or movement of the air.”

Being able to move with the air is how sensors are able to tell when a sound is present and which direction it is coming from.

Miles made headway with acoustic sensors in 2017 by using spider silk dipped in gold as a thin, flexible sensor to make a microphone with remarkably flat frequency response. This sensor incorporated a magnet in order to convert the silk motion into an electronic signal.
