近年来，电池供电的嵌入式电子设备的数量急剧增加。然而，这些设备的寿命受到电池容量的限制。能量收集是克服这种限制的有效解决方案;然而，传统上采用大的能量缓冲器来处理源的时间变化。这些缓冲器通常需要相当长的时间来充电，同时引入成本、尺寸和重量开销。能量驱动系统专门设计为从能量收集源运行，而不会过度提供能量存储，使系统看起来像“电池”。此外，一个瞬时供电的系统能够在间歇性供电的情况下维持计算，而不需要额外的能量存储。虽然这显示了很大的希望，但这些系统对现实生活应用的广泛适用性还有待证明。本文提出了一种瞬时供电的无线自行车行程计数器，它可以测量距离、速度和有效骑行时间，并无线传输数据。该系统通过从车轮的旋转中获取能量来维持运行，最低运行速度为6 kph，同时根据所获取的能量调整其运行。
There has been a dramatic increase in recent years in the number of battery-powered embedded electronic devices. However, the lifetime of these devices is limited by battery capacity. Energy harvesting is an efficient solution to overcome this limitation; however, large energy buffers have been traditionally employed to tackle the temporal variation of the source. These buffers typically require considerable time to charge while introducing a cost, size and weight overhead. Energy-driven systems are specifically designed to operate from an energy harvesting source, without overprovisioning energy storage to make the system appear "battery-like". Furthermore, a transiently-powered system is capable of sustaining computation despite an intermittent supply, without the need for additional energy storage. While this shows much promise, the wide applicability of these systems to real-life applications is yet to be demonstrated. This paper presents a transiently-powered wireless bicycle trip counter which measures distance, speed and active cycling time, and transmits data wirelessly. The system sustains operation by harvesting energy from the rotation of the wheel, operating from a minimum speed of 6kph, while adapting its operation in response to the harvested energy.
