Polyustimulator – Ultrasound driven piezoelectric stimulator

Polyustimulator – Ultrasound driven piezoelectric stimulator for neuromusculoskeletal rehabilitation

As existing electroceutical stimulators are bulky with limited life span and poses transmission eﬃcacy and safety concerns, wireless power delivery to electrical implants deep inside the body remains a critical chal-lenge. The PolyUStimulator presents a battery-free, ultrasonically-powered, piezoelectric stimulator for functional muscles, nerves and bones. Ultrasounds can reach deep into the body where conventional inductive energy cannot reach safely; it is also safe from radio frequency interference; and is fully MRI and X-ray compatible. This innovation can treat patients, ranging from neurological to orthopedic conditions, whom are paralyzed or suﬀering from non-union bone fractures or neuromusculoskeletal pain.
