野生动物追踪装置是获得有关自由漫游动物的运动、迁徙、出生分散、家园范围、资源利用和群体动态的详细信息的关键。尽管这些设备被广泛使用，但由于技术限制，对大多数动物来说，跟踪整个生命周期仍然是一个相当大的挑战。在小动物身上使用电池供电的野生动物标签受到设备质量的限制。带有太阳能电池板的微型设备有时可以解决这一挑战，然而，生活在弱光条件下的夜行动物或动物使太阳能电池几乎毫无用处。对于大型动物，电池重量可能更高，电池寿命成为主要挑战。一些研究已经提出了解决这些限制的方法，包括在动物身上收集热能和动能。然而，这些概念受到尺寸和重量的限制。在这项研究中，我们使用了一个小而轻的动能收集单元作为定制野生动物跟踪装置的电源，以研究其对动物终身跟踪的适用性。我们将Kinetron MSG32微型发电机和最先进的锂离子电容器（LIC）集成到一个定制的gps跟踪设备中，该设备能够通过Sigfox“物联网”网络远程传输数据。对家犬（n = 4）、野外漫游的Exmoor小马（n = 1）和wisent （n = 1）进行了原型测试。其中一只家犬每天产生高达10.04焦耳的能量，而埃克斯穆尔小马和威森特平均每天分别产生0.69焦耳和2.38焦耳的能量。我们的研究结果表明，动物物种和安装方法在能量产生方面存在显着差异，但也突出了该技术在需要终身跟踪动物的生态研究中有意义的进步的潜力。Kinefox的设计是开源的。
Wildlife tracking devices are key in obtaining detailed insights on movement, animal migration, natal dispersal, home-ranges, resource use and group dynamics of free-roaming animals. Despite a wide use of such devices, tracking for entire lifetimes is still a considerable challenge for most animals, mainly due to technological limitations. Deploying battery powered wildlife tags on smaller animals is limited by the mass of the devices. Micro-sized devices with solar panels sometimes solve this challenge, however, nocturnal species or animals living under low light conditions render solar cells all but useless. For larger animals, where battery weight can be higher, battery longevity becomes the main challenge. Several studies have proposed solutions to these limitations, including harvesting thermal and kinetic energy on animals. However, these concepts are limited by size and weight. In this study, we used a small, lightweight kinetic energy harvesting unit as the power source for a custom wildlife tracking device to investigate its suitability for lifetime animal tracking. We integrated a Kinetron MSG32 microgenerator and a state-of-the-art lithium-ion capacitor (LIC) into a custom GPS-enabled tracking device that is capable of remotely transmitting data via the Sigfox ‘Internet of Things’ network. Prototypes were tested on domestic dog (n = 4), wild-roaming Exmoor pony (n = 1) and wisent (n = 1). One of the domestic dogs generated up to 10.04 joules of energy in a day, while the Exmoor pony and wisent generated on average 0.69 joules and 2.38 joules per day, respectively. Our results show a significant difference in energy generation between animal species and mounting method, but also highlight the potential for this technology to be a meaningful advancement in ecological research requiring lifetime tracking of animals. The design of the Kinefox is provided open source.
