Flexible pressure sensors have great potential for wearable applications such as human health monitoring and human–computer interaction, which require different trade-offs between the sensitivity operating range. However, preparing washable wide-range piezoresistive remains a challenge. Here, we developed porous flexible elastomer sponge based on carbon nanotube composite network coating with extremely high stability washability over wide Specifically, sugar template was used to fabricate homogeneous macroporous PDMS substrate, dip-coated MCNT-PDMS conductive layer. The degree of adhesion formed substrate layer resulted in greatly enhanced mechanical properties stability, while improving exhibited broad range 0–650 kPa, demonstrating excellent (0.0049 kPa−1 0–74 0.0010 74–310 0.0004 310–650 kPa), well fast response time 143 ms recovery 73 ms, long-term cycling 10,000 cycles, stability. Finally, demonstrate that can be applied gesture monitoring, motion gait monitoring.
