Fig. 5: Janus aerogels for pressure sensing and human motion monitoring.
a The stress–strain curves of the Janus aerogels of Ti3C2Tx/GO (20 wt% GO):GO at different sets of strains. b Digital images showcasing the compressibility of Ti3C2Tx/GO (20 wt% GO):GO aerogels. c The cyclic piezoresistive sensing performance of the Janus aerogel under different compression strains. The d sensitivity and e, f response/recovery times of the fabricated sensor. The recorded signal for g soft and h hard press of the sensor. The recorded response of the sensor i before and j after 2000 bending cycles under real conditions. The capability of the sensor for monitoring k finger movements and l contraction–relaxation biceps muscles, both as large-scale body movements. The recorded response for various subtle human motions, including m talking, n coughing, and o facial muscle movements. Scale bar in (b) corresponds to 2 cm.
