Abstract Wearable batteries are anticipated to revolutionize the field of personalized medicine and reduce healthcare costs by enabling the widespread adoption of wearable sensors. However, the current lack of a suitable power source poses a significant hurdle to the advancement of wearable sensor technology. To address this challenge, our group in Brazil has proposed the utilization of bioinspired organic and organometallic compounds in gel-based electrolytes, incorporating flexible carbon fibers as current collectors. In the BEPE project, we aim to further advance wearable battery technology by developing new miniaturized electrodes utilizing 2D materials derived from graphene monolayers. Graphene, known for its robustness as a current collector, high electrical conductivity, and mechanical flexibility, presents a promising avenue for miniaturizing and enhancing the flexibility of batteries. Collaborating with Humboldt-Universität zu Berlin, we will explore various types of electrodes, including multilayer graphene, multilayer graphene with structural defects, and edge-rich multilayer graphene. The primary objectives of this project are to optimize the current collector design and enhance the performance of miniaturized organic batteries. By leveraging the unique properties of graphene, we strive to increase the power output and extend the lifetime of these batteries. Through this project, we aim to push the boundaries of wearable battery technology, paving the way for its practical implementation in a wide range of applications. The successful development of miniaturized organic batteries utilizing graphene-based electrodes holds immense potential in revolutionizing wearable sensor technology. This advancement could unlock new possibilities for monitoring and improving individual health, ultimately leading to more personalized and efficient healthcare solutions. (AU) | |
