Abstract

Highly sensitive sensors with extensive applications are extremely desired in the next-generation wear-able electronics for human motion monitoring,human-machine interface and intelligent robotics,while single-functional pressure sensors cannot fulfill the growing demands of modern technological advances.Herein,an all-fabric and multilayered piezoresistive sensor based on conductive metal-organic frame-work/layered double hydroxide(cMOF/LDH)hetero-nanoforest is demonstrated to achieve multiple ap-plications including pulse detection,joint motion detection,sound detection and information transmis-sion.Benefiting from the synergism of cMOF/LDH hetero-nanoforest and multilayered structure,the sen-sor exhibits a high sensitivity(1.61 × 109 kPa-1)over a broad pressure range(0-100 kPa),a fast re-sponse/recovery time(71 ms/71 ms)and a low detection limit(18 Pa),as well as reliable dynamic sta-bility(8000 cycles).It is gratifying to note that the introduction of cMOFs endows the sensor with the potential to detect the concentration of NH3(1-100 ppm)and sunlight intensity(10-100 mW cm-2).This work shows great potential in multifunctional sensing,which enlightens a strategy for advancing the development process of highly sensitive intelligent wearable devices.
