Flexible piezoresistive pressure sensors have received much attention due to their potential for applications in personalized real-time health detection, human-computer interaction, and the Internet of Things (IoT). However, achieving a fast response high sensitivity while keeping cost low remains key concern researchers. In this paper, we simulated spiky surface hedgehog skin by hydrothermal growth nickel molybdate on carbonized sponge. Based this, MXene material was compounded process immersion sonication, thus MXene/NiMoO4@CMF (MNC) successfully prepared. After assembly into an MNC sensor, it shows good performance. terms sensitivity, is 31.1 kPa–1 range 0–10 kPa, 15.7 10–15 3.3 15–64 kPa. Moreover, also has capability (500 ms) excellent cyclic stability (95.7%). addition, integrated sensor with ESP8266 WiFi Module IoT Development Board autonomously programmed UI interface. Therefore, capable monitoring human real time displaying abnormal statuses interface when test value outside normal range. summary, based its sensing performance application, wide wearable devices, IoT, monitoring.

Soft tactile sensors outputting fluidic signals have many potential applications in soft microfluidic devices and robots. However, existing systems been limited to a single or few parallel, so they are not comparable the state‐of‐the‐art electrical resistive capacitive touchpads, which can detect rich information, including touch location, pressure, area, even multiple touches simultaneously. This work reports micropneumatic touchpad. The touchpad consists of 32 pneumatic channels inside elastomer, with 16 aligned row‐wise column‐wise. flow resistance each channel is measured using pressure divider. When pad touched, cross‐sectional area close contact location deforms, changes those channels. With sensing channels, depth, contact, two simultaneous be detected. Letters hand‐written on reconstructed from data. assumption sparsity, map, value at × grid point, also reconstructed. opens path replace electronic all‐fluidic alternatives.
