Kinetic instead of batteries for animal tracking

For animal tracking, the energy issue is problematic. This has been tackled by the N4C partner Universidad Politecnica de Madrid. In the article “A HeterogeneousWireless Identification Network for the Localization of Animals Based on Stochastic Movements” they explain their take on this issue, and a proposal for solution:

The improvement in the transmission range in wireless applications without the use of batteries remains a significant challenge in identification applications. In this paper, we describe a heterogeneous wireless identification network mostly powered by kinetic energy, which allows the localization of animals in open environments. The system relies on radio communications and a global positioning system. It is made up of primary and secondary nodes. Secondary nodes are kinetic-powered and take advantage of animal movements to activate the node and transmit a specific identifier, reducing the number of batteries of the system. Primary nodes are battery-powered and gather secondary-node transmitted information to provide it, along with position and time data, to a final base station in charge of the animal monitoring. The system allows tracking based on contextual information obtained from statistical data.
