Nature-Inspired Pressure Interactive Alternating Current Electroluminescent for Orientation Indication, Visual Sensing, and Remote Monitoring

Most 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 device remaines excellent performance 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. In this study, a device called MPI-ACEL that integrates pressure sensing and visual monitoring is proposed. It utilizes hydrogel and electroluminescent display, offering real-time pressure sensing and static delay monitoring. MPI-ACEL presents a flexible and effective solution for visual pressure sensing, environmental indication, and remote monitoring in multiple dimensions.image
