Abstract
AbstractMost current visual pressure sensing devices are greatly limited by less integrated functions. To address this issue, a multi‐dimensional pressure interactive visual monitoring device is proposed based on the temperature and humidity adaptive hydrogel. Specifically, this device is composed of a buffer grid layer that divides it into pressure sensing and luminous display areas. With a double network structure incorporated with a LiBr liquid, the pressure sensing area demonstrates great deformability, resilience, and self‐absorption. In a dynamic mode, the best pressure can be detected at high humidity and low temperature, displaying a range of up to 45 N and offering feedback at a minimum load of 0.25 N. Importantly, the performance of the device remains excellent even after the dynamic compression repeating over 1300 cycles. In static mode, MPI‐ACEL achieves a delay time of up to 390 min. Finally, it is anticipated that this multifunctional device will provide a new, flexible, and effective scheme for visual pressure sensing, environmental adaptive directional indication, and multi‐dimensional remote monitoring.
