Dynamic Schottky direct-current (DC) generators hold great promise for ambient mechanical energy harvesting as it overcomes the low-current output limitation in conventional approaches. In our recent work published in Advanced Functional Materials, a high-performance, flexible Schottky DC generator with metal/conducting polymer sliding contact system is demonstrated, which exhibits a large current density (J) up to 20 A m–2 for single contact geometry and a scaled-up DC output reaching 200 µA (J = 0.73 A m–2) and 0.8 V. The design of flexibility in such a Schottky DC generator is inherited from the long-chain polymer concept, leading to the demonstration of a variety of device configuration of free-standing thin film, supported thin film and nanocomposite prototype toward practical applications. The concept of a flexible Schottky generator not only shows great promise for next-generation, self-powered wearable devices, but also provides potential mechanisms for developing novel wearable sensors. PhD student Ruizhe Yang is the first author of the work:
Monica Cortes, a first-year undergraduate student in Mechanical and Aerospace Engineering at UB, has received the prestigious Gustav and Grete Zimmer Memorial Scholarship to support her research in Dr. Liu's lab. Many congratulations!
