Tóm tắt

The importance of continuous and reliable pulse wave monitoring is constantly being increased in health signal monitoring and disease diagnoses. Flexible pressure sensors with high sensitivity, low hysteresis and fast response time are an effective means for monitoring pulses. Herein, a special wave-shaped layered porous structure of carbonized wood cellulose sponge (CWCS) was constructed based on natural wood (NW). Thermoplastic polyurethane (TPU)/CWCS (PCWCS) composite flexible pressure sensitive elements were formed by immersing a TPU solution into the CWCS skeleton. The PCWCS-4 % based sensors exhibited high sensitivity of 164.77 kPa
