A battery-less wireless sensor for use in harsh and hazardous environments
The Adaptive Plant project will develop a battery-free wireless sensor platform for monitoring plant and process parameters in harsh/hazardous environments. The sensor node is powered by harvested thermoelectric power using the latest commercially available technologies and the core sensor module will be connected to low power sensor components to take measurements.
The core harvester sensor node is designed to generate 25mW of electrical power with a 0.5% overall thermal efficiency and store the unused electrical energy in a buffer which allows part of the sensor system with higher power consumption requirements – the wireless transmitter particularly- to operate seamlessly in burst mode.
The system will be designed to be compatible for typical applications where measurements such as pressure, flow rate, temperature and vibration monitoring are necessary. It will have the ability transmit the data to a central database from nodes at different geographical locations limited to <1km distance.
Project end date
- To deliver a harvester sensor device extracts minimum 25mW power to supply the electrical storage device.
- To allow plant and processing facility operators to gather data real time in a cost effective way.
- Create intellectual property and jobs within the collaborating partners
- Eliminate the need for an electrochemical battery
- The majority of the aims were fully achieved, the project proved the concept and moved the final prototype onto a high technology readiness level
- Further testing work has been identified and a product development program has been put in place to develop the prototype into a commercial product
- The project has had a big impact on evolving the company’s future electronics product line and ETDYN’s competitiveness in the marketplace
- Further development work is currently on-going and the product is expected to be released in 2015
