A SOLUTION TO
LIFE-LONG TRACKING OF WILDLIFE
01 WHY energy harvesting?
Modern low-power sensors enable precise local, remote or autonomous control of a vast range of products. Their use is rapidly proliferating in the remote monitoring within hospital intensive care suites, oil refineries, and transportation infrastructure, and security systems. They are key components for a vast range of applications with global markets. Importantly, energy harvesting (EH) technology allows small, standalone sensors to function continuously for extended periods of time — decades, even — without power-line connections or battery replacements. This technology greatly enhances the problem-solving capability of low-power sensors and its use is growing rapidly. For that reason, an energy-harvesting function is shown as the power-source element in the block diagram of a typical sensor product:

water & wastewater
02 Key benefits
1 W Power - Establishing a power benchmark is key to a viable source of electricity for remote devices. The range of RMS power is customizable based on the harvester size and the range of excitation frequency.
50% Bandwidth - Having a broad frequency response would help sustain power under random excitations, such as vibrations induced by fluid flows or animal gait movement.
300 C - Tolerating high-temperatures would greatly benefit sensing applications in remote, harsh environments. These include off-shore energy or geothermal drilling conditions in wet or dry environments.

Wildlife tags are currently being used for wildlife monitoring to understand population behavior of aerial, terrestrial, and marine animals. The major shortcoming is battery life. Lifetag is a retrofit that enables long-lasting battery tags. Batteries are charged through harvesting energy from flow-induced vibrations. The approach mitigates battery limitation and reduces the overall cost of powering devices in remote undersea locations.
