Sustainability through microwave power transmission
Researching next-generation wireless power technologies, from µW to W levels, to enable sustainable, low-waste, and user-friendly electronics, from remote sensors to wearables and implants.
Smart bandages enabled by wireless power
The ability to safely and reliably deliver watts of power to body-worn could enable a range of applications from anti-bacterial drug-free wound dressings to power-efficient heaters.
Our RF energy harvesting research is supported by a UK Intelligence Community Research Fellowship.
"Using electromagnetism as an energy source to power batteries is of central importance to designing devices for future threat detection.
I am looking forward with great anticipation to the outcomes of this cutting-edge research."
- Alex van Someren, Chief Scientific Adviser for National Security to HM Government
High-Sensitivity 2D Rectenna Surfaces
Co-designing large rectenna arrays based on electrically small elements enabling the surface to maintain a collection aperture exceeding its physical footprint.
Our rectenna surfaces can be designed for different frequency bands and have been demonstrated powering wireless sensor nodes with unprecedented sensitivities, for safe and compliant long-range wireless power transfer (WPT).
Contact us if you would like to use our harvester in your systems.
Pushing the Power Limits of Large-Area Electronics
We are leveraging near-field non-radiative resonant wireless power transfer (WPT) to safely and efficiently deliver high power levels (over 10 W) to wearable, flexible, and large-area electronics for on-body applications.
Our high-power flexible and large-area wireless power receivers can provide power to various applications ranging from consumer devices to biomedical stimulation circuits. We are designing novel printable components with unmatched power handling capabilities, enabling more sustainable manufacturing of large-area wireless-powered systems.
The applications of our work have been featured in many media outlets including The Independent, The Engineer, and many others.
RX Watt Ltd., Wireless Power Beyond the Lab
Our university spin-out RX Watt aims to simplify "re-charging" and enable battery-free sensing, building on world-leading and patent-pending simultaneous wireless information and power transfer (SWIPT) research.
From September 2023, RX Watt has been accepted on the Octopus Ventures Springboard accelerator program. To date, we have been supported through EPSRC Impact Acceleration and RAEng grant funding.
Our wireless power research enables a range of application from wearable, biomedical, to industrial. Find out more in the University News.
