Exclusive: Running, Walking, or Opening Doors Could Soon Generate Power for Your Devices

September 1, 2024

Imagine your morning jog not only energizing you but also powering your wearable tech. This vision might soon become a reality thanks to a groundbreaking development by the University of Surrey’s Advanced Technology Institute (ATI). Their latest innovation, a flexible nanogenerator, boasts a remarkable 140-fold increase in power density over traditional models, potentially rivaling today’s solar panels.

Unprecedented Power Efficiency

Published in the journal *Nano Energy*, this advanced nanogenerator can transform small mechanical motions—like those from a morning run or the simple act of opening a door—into substantial electrical power. Conventional nanogenerators might produce around 10 milliwatts, but Surrey’s device can generate over 1,000 milliwatts. This significant leap in energy output opens up a range of possibilities for everyday applications, from wearable devices to off-grid sensors.

Innovative Design and Functionality

The new technology works through a process akin to a relay race. Instead of a single electrode managing all the energy transfer, multiple tiny electrodes work together to accumulate and pass on electrical charge, enhancing overall energy efficiency. This process, known as the charge regeneration effect, is driven by 34 miniature energy collectors crafted with precise laser technology, making it scalable for manufacturing and further improvements.

Dr. Delavar Hussain, lead author of the study, expressed excitement about the potential of this technology. “Our nanogenerator captures the energy from routine movements, converting it into usable power for various applications,” he said. The technology’s ability to generate substantial power from minimal movement could transform sectors ranging from smart home systems to healthcare devices.

Looking Ahead

Dr. Bhaskar Dudem, co-author, hinted at the broader impact of this innovation. “We’re preparing to launch a company focused on non-invasive healthcare sensors using this technology. The potential for spin-offs in sustainable medical technology and beyond is significant.”

Professor Ravi Silva, another co-author, emphasized the global implications. “With the anticipated surge in IoT devices, local green energy solutions are crucial. This nanogenerator could provide a convenient, wireless power source for a range of small devices, contributing to a more sustainable future.”
