Wearable pressure sensors are essential for real-time monitoring of human activities and the status of biomimetic robots.Recently, a joint team of Zhang Mingjia, an associate researcher at the Qingdao Institute of Bioenergy and Processes, Chinese Academy of Sciences, and Huang Changshui, a researcher at the Institute of Chemistry, Chinese Academy of Sciences, prepared an ultrasensitive pressure sensor sponge through a simple metoda, uresničevanje ultra občutljivega spremljanja nosljivega zdravja. Zaznavanje tlaka. Povezani rezultati so bili objavljeni na spletu v reviji Nano Communications 25. marca 2022.
In this study, researchers fabricated an ultrasensitive pressure sensor sponge using liquid metal modulation of nitrogen-doped graphene nanosheets.Since the liquid metal in the sponge skeleton structure helps to tune the contact area with nitrogen-doped graphene nanosheets under pressure, thereby promoting charge transfer at the interface, such sensors have fast response and recovery speed, response/recovery time is 0.41/0.12 sekunde.
Omeniti velja, da lahko tekoči kovinski senzor gobice tlaka natančno spremlja človeški impulz, kožni tlak, požiranje grla in druge dejavnosti v realnem času, kar kaže na široke možnosti uporabe.
Priročna in nizkocenovna metoda za izdelavo enostavnih senzorjev tlaka, razširitev uporabe potenciala tekočih kovinskih kompozitov za razvoj prihodnjih elektronskih kož.
