A wearable ultrasound system can produce clinically relevant information about muscle function during dynamic physical activity. When an individual is performing a specific exercise for rehabilitation, the devices can be used to ensure that the target muscle is actually being activated and used correctly.

Other applications include providing athletes with insights into their physical fitness and performance, assessing and guiding recovery of motor function in stroke patients, and assessing balance and stability in elderly populations during routine everyday tasks.

The systems use a patented approach that relies on transmission of long-duration chirps, which allows it to perform ultrasound sensing using the same components one might find in their car radio. The modified approach allowed the team to design a simpler, cheaper system that could be miniaturized and powered by batteries. This let them design an ultrasound monitor with a small, portable form factor that could be attached to a patient. (Image credit: Parag Chitnis)
