Abstract
- Flexible piezoionic sensors with softness haptic perception are critically important to artificial intelligence. However, their sensitivity is limited to relatively low level far from practical application because ion transfer is always restricted at surface and in-plane spaces of electrode materials. Here, we discover ultrafast out-plane ion transfer enabled by triangle pores existing in graphdiyne architecture, and then prepare flexible sensors with excellent performances exceeding other reported piezoionic materials. It delivers high piezoionic voltage with excellent cycling stability. The high performances are further verified by ion-pore structure model with pore utilization factor of 99.3%. Moreover, accurate patch detection of blood pressure is realized easily and stably based on graphdiyne piezoionic sensors, which completely slips the leash of cuff problem on commercial sphygmomanometer. Our work sheds light on in-depth discovery of new properties of graphdiyne for electrochemistry. [Display omitted] [ABSTRACT FROM AUTHOR]
