Flexible piezoelectric sensors are widely used in energy harvesting and sensing, illustrating the potential applications in self-driving wearable devices. However, the self-healing sensors by light and heat can effectively solve the problem of damage in practical applications. Therefore, the thermally healing piezoelectric sensors with different multilayers integrating the ATO electrode film and BNT piezoelectric film are proposed and investigated, which can use natural resources (under sunlight) to repair its defects. It also has a high sensitivity of 2.09 V·kPa⁻¹, a fast response time of 66 ms, a maximum output voltage of 61 V and an output power of 30 μW. The results show that the PES has great potential in future applications.

柔性压电传感器广泛用于能量收集和传感，说明了在自动驾驶可穿戴设备中的潜在应用。然而，光热自愈传感器可以有效解决实际应用中的损坏问题。因此，提出并研究了集成 ATO 电极膜和 BNT 压电膜的不同多层热修复压电传感器，可以利用自然资源（在阳光下）修复其缺陷。^{它还具有2.09 V·kPa -1}的高灵敏度、66 ms的快速响应时间、61 V的最大输出电压和30 μW的输出功率。结果表明，PES在未来的应用中具有巨大的潜力。
