Powering disposable wearables has long been a challenge due to the reliance on bulky, short-lived batteries. For this reason, researchers from SUNY Binghamton have developed a new paper-based moist-electric generator specifically for disposable wearable electronics. It addresses the challenge of integrating sustainable power sources into short-term wearables, which are often hindered by bulky and environmentally damaging batteries. This generator leverages ambient moisture to produce continuous power, which eliminates the need for frequent recharging or replacement.
The device features a biodegradable paper substrate infused with bacterial endospore biofilms. These biofilms create gradients of functional groups and nanoporous structures, which enhance moisture capture and ion generation—key components for sustained electricity production. To further optimize performance, the generator includes a hydrophobic-hydrophilic Janus paper layer that captures ambient moisture and directs it efficiently to the generator. The design ensures consistent power output, even in low-humidity environments.
The generator's lightweight, flexible, and eco-friendly design allows it to maintain stable performance under various conditions, including bending and prolonged wear. Its scalability makes it suitable for mass production, offering a cost-effective solution for health monitoring and diagnostic devices. Additionally, its disposable nature minimizes environmental impact, which addresses the growing issue of electronic waste.
This technology's application in real-time health monitoring could revolutionize personalized medicine, making it more accessible and more importantly, environmentally friendly.
