Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a revolutionary wearable ultrasonic sensor that adapts to the shape of the body and supports both diagnostic and therapeutic applications.
Whereas conventional wearable ultrasonic systems often suffer from low power and limited structural stability, this new sensor offers a flexible and dimensionally stable design that enables accurate imaging and targeted treatment without surgical intervention.
From flexible to rigid
The research team, led by Professor Hyunjoo Jenny Lee of the Faculty of Electrical Engineering, developed a so-called ‘flex-to-rigid’ (FTR) CMUT (capacitive micromachined ultrasonic transducer) sensor. The innovation uses a low-melting-point alloy (LMPA) that liquefies when heated, making the device flexible. Once the power is turned off, the metal...
