Description | We developed the world's first maximum power point tracking system with a power consumption of 40 microwatts. This task is typically carried out slowly (in steps of seconds and minutes) by a PC, requiring many watts. Our system can track the optimal power to be extracted from a source using five orders of magnitude less power. |
Exploitation Route | This work has been taken forward into new application areas, such as health monitoring. In order to further reduce the power, and therefor allow the miniaturisation of the power source, the circuits were integrated onto chips. |

Description | The results led us to understand how to operate microcontroller circuits when very little power is available. These results where then used in the 2013-16 SAVVIE research project to develop electronics that stays alive under intermittent power. Under the 2014-2019 SPHERE health sensing project, one work package (2014-2016) took this forward to develop and Sensor Driven electronics that can monitor sensors using nanowatts of power. This meant energy harvesting was now viable and that batteries can last for decades in certain applications. The technology was prepared for commercial sampling using an EPSRC Acceleration Award. Once successfully trialled by industry, this technology was licensed in 2017 to Sensor Driven Ltd, which received private investment, UK Innovate UK awards, and which is currently employing engineers to create electronic sensors that do not require battery replacement, and to set up trials with industry. |
