“…High sensitivity is achieved when small changes in pressure result in significant capacitance variations ΔC, with the ΔC / C 0 of iontronic pressure sensors reaching up to 10 6 due to the formation of the electric double layer (EDL) at the dielectric/electrode interface. 36,37 Various configurations of iontronic pressure sensors based on the gradient hydrogel structure were studied for sensitivity changes and comparisons (Figure S11). The results revealed that when only the upper layer had micro-pyramid structures, whether they were at the same level or graded, the sensitivity was consistently low, and the response signal was nonlinear.…”

Flexible pressure sensors, vital for medical, human-machine interaction, and intelligent recognition applications due to their high-sensitivity, excellent-linearity, and broad-pressure response, face challenges in achieving a harmonious balance among these attributes. Inspired by the gradient modulus in human skin layers, we proposed a pioneering method to adjust the gradient elastic modulus of amino trimethylene phosphonic acid (ATMP)-assisted polyvinyl alcohol (PVA) hydrogel through the Hofmeister effect, introducing micro-pyramid electrodes. This innovative approach successfully constructs a bio-gradient gel iontronic sensor (BGGITS) with an ultra-wide-range perception. The BGGITS exhibits a linear high-sensitivity of 700 kPa-1 within a broad-pressure detection range of up to 800 kPa. The composite design, integrating gradient gel and microstructure electrodes, demonstrates exceptional pressure resolution and mechanical stability. This biomimetic skin pressure sensor holds promise for achieving linear high-sensitivity across a broader pressure range simultaneously and may find applications in electronic skin for health monitoring and tactile perception in the future.

Over the past decades, tactile sensing technology has made significant advances in the fields of health monitoring and robotics. Compared to conventional sensors, self‐powered tactile sensors do not require an external power source to drive, which makes the entire system more flexible and lightweight. Therefore, they are excellent candidates for mimicking the tactile perception functions for wearable health monitoring and ideal electronic skin (e‐skin) for intelligent robots. Herein, the working principles, materials, and device fabrication strategies of various self‐powered tactile sensing platforms are introduced first. Then their applications in health monitoring and robotics are presented. Finally, the future prospects of self‐powered tactile sensing systems are discussed.
