Abstract

The osteofascial compartment syndrome is a common syndrome in orthopedics clinical practice. The body fluid pressure is the key indicator of the need for surgery. The traditional needling pressure measurement method is traumatic, single-point, and wired, which is very inconvenient in practice. As a promising alternative measurement method, anon-invasive, multi-point, and wireless flexible wearable pressure measurement sensor was proposed in this work. The sensor has 7 flexible pressure measurement units to realize multi-point measurement. The units were fabricated by unique printing electronics technology, with high precision and flexibility. ZigBee protocol was used for real-time wireless data transmission. A35.9mm*56.6mm flexible printed circuit board(FPCB)was designed and optimized for the pressure readout and wireless communication. The FPCB was powered by a small 3V button battery. Typical specifications of the sensor are as follows: sensing unit size 10*4 mm; measurement range [0, 100] N; measurement precision 2.5 N; maximum wireless transmission distance50 m; maximum bending radius 2 mm. Further optimization and experiments, including animal experiments, are in progress.
