Abstract

Ingestible and implantable devices are presented as promising approaches for health monitoring and disease treatment once they provide high quality information and comfortability. However, currently these devices are powered by lithium or silver batteries, which are toxic for the user and if an accident occur (electrolyte leakage or breaking) can promote irreversible injuries. Organic/Oganometallic molecules from nature or bioinspired poses big application potential since they are low toxic, renewable, and allow electrochemical potential modification by the proper insertion of functional groups. Thus, this direct doctoral project proposes building up a Bioinspired Organic Microbattery (BOM) using molecules from the nature or bioinspired aiming a safer power supply. Furthermore, it proposes the use of hydrogels from natural sources, for example, polysaccharides and peptides, as electrolyte. Cyclic voltammetry, chronoamperometry, chronopotentiometry and electrochemical impedance spectroscopy will be used as characterization techniques for the BOM and infrared vibrational spectroscopy, nuclear magnetic resonance and rheology in the hydrogel structural and mechanical characterization. The BOM enclosure will be constructed from biocompatible and biostable polymers using 3D printing technique. Finally, this project will contribute to fundamentals knowledge about electrochemical processes in hydrogels and build up a safe microbattery for the growing market of smart biomedical devices. (AU)
