  • Wearable sensor for continuous monitoring of tissue mechanics
    Patent number: 12653450
    Abstract: A wearable device includes an elastically compliant body having a side for attaching to skin of a patient, a plurality of accelerometers for receiving acoustic wave data from acoustic waves transmitted by a transducer, a short-range radio transmitter for transmitting the acoustic wave data to a computing device, a processor for receiving the acoustic wave data from the plurality of accelerometers and providing the acoustic wave data to the short-range radio transmitter, and a battery for providing power to the processor, the plurality of accelerometers, and the short-range radio transmitter. A distance between each accelerometer of the plurality of accelerometers is predetermined. The processor, the plurality of accelerometers, the short-range radio transmitter, and the battery are embedded within the elastically compliant body.
