论文摘要
传感器节点的连续无电池操作需要超低功率传感和数据存放技术。在这里，我们报告说，通过将传感器/换能器信号直接耦合到基于福勒 - 诺德海姆量子隧道的全球渐近单调动力系统中，人们可以在能量预算上实现自动传感，该能源预算目前使用常规能量收获方法无法实现。所提出的设备使用差分体系结构来补偿环境变化，并且该设备可以保留从小时到几天的持续时间的感知信息。在理论运行能量预算少于10个attojoules的情况下，我们证明，当与微型压电传感器集成时，提议的传感器数据库可以测量由于环境机械加速度而没有任何其他外部功率，因此可以测量累积的“动作”。
Continuous, battery-free operation of sensor nodes requires ultra-low-power sensing and data-logging techniques. Here we report that by directly coupling a sensor/transducer signal into globally asymptotically stable monotonic dynamical systems based on Fowler-Nordheim quantum tunneling, one can achieve self-powered sensing at an energy budget that is currently unachievable using conventional energy harvesting methods. The proposed device uses a differential architecture to compensate for environmental variations and the device can retain sensed information for durations ranging from hours to days. With a theoretical operating energy budget less than 10 attojoules, we demonstrate that when integrated with a miniature piezoelectric transducer the proposed sensor-data-logger can measure cumulative "action" due to ambient mechanical acceleration without any additional external power.
