Mechanoluminescent materials featuring mechanical-to-optical conversion have been vigorously studied as a carrier of optical sensing technology in the field of mechanical sensing due to their self-recovery, visualization, and non-contact sensing characteristics. However, the impact of the human living environment such as temperature, humidity, corrosive substances, etc. on optical sensing materials cannot be ignored, which greatly affects the accuracy of optical sensing. To overcome these barriers to the accuracy of these factors, a flexible mechanoluminescent composite device with high brightness in a bright and dark environment based on Ce3+-doped garnet structure phosphors Tb3Al5O12 was proposed. Under the action of repeated mechanical stimulation, the mechanoluminescence (ML) intensity presents good self-recovery performance, and the ML intensity shows a zero-thermal-quenching performance in the range of 0–100 °C. In addition, the evaluation of moisture resistance was performed under different durations in the water, proving that the intensity of ML can hardly be affected by the humid environment. Accordingly, a transmission system based on a robot finger was proposed to simulate the application of the human tactile system. The results showed great potential for Tb3Al5O12: Ce3+-based ML composite devices in advanced optical multimode sensors to promote their diversified application.

基于机械发光的环境稳定自恢复柔性复合机械传感器
机械光转换的机械发光材料由于其自恢复、可视化和非接触传感等特点，作为光学传感技术的载体在机械传感领域得到了广泛的研究。然而，温度、湿度、腐蚀性物质等人类生活环境对光学传感材料的影响不容忽视，极大地影响了光学传感的准确性。为了克服这些因素的准确性障碍，基于 Ce 3+掺杂的石榴石结构荧光粉 Tb 3 Al 5 O 12的在明亮和黑暗环境中具有高亮度的柔性机械发光复合器件被提议。在反复机械刺激作用下，机械发光（ML）强度表现出良好的自我恢复性能，ML强度在0-100℃范围内表现出零热猝灭性能。此外，在不同的水中时间下进行了耐湿性评估，证明ML的强度几乎不受潮湿环境的影响。据此，提出了一种基于机器人手指的传输系统来模拟人类触觉系统的应用。结果表明，Tb 3 Al 5 O 12 : Ce 3+基ML复合器件在先进光学多模传感器中具有巨大潜力，可促进其多元化应用。
