Man develops device to hear cracking knees

Omer suffered knee pain himself and had been thinking about developing such a device for some time. He was a discus thrower and a three-time NCAA All-American at Stanford University and the school record holder.

Because of whirling around for several years, and because of the stress and strain of weight required in the training, his knees started to crack.

“I would always feel like my knee was creaking or popping more if I was putting more stress on it,” the professor said.

When the Defense Advanced Research Projects Agency presented a call for research proposals on wearable technologies for assisting rehabilitation, the researcher pitched his idea.

So Omer started working on knee band with microphones and vibration sensors to listen to and measure the sounds inside the joint. Acoustic electronics turn them into moving graphs that may someday be medically useful.

This innovation can lead to a future device to help orthopaedic specialists assess damage after an injury and track the progress of recovery.
