摘要：
In this paper, we report a wearable and flexible capacitive pressure sensor based on porous dielectric elastomer with ultra-high sensitivity and stability. The capacitance response to a wide pressure range of 0 similar to 130kPa was investigated, which is generally considered as a human tactile pressure regime. The porous dielectric layer based pressure sensor showed highly sensitive and stable performance with pore-closing mechanism over the whole tactile pressure regime without any drift or structural instability. Finally, we demonstrated a bandage-type wearable pressure sensor for real-time monitoring of human wrist pulse.
