BioSparks: Jewelry as Electrochemical Sweat Biosensors with Modular, Repurposing and Interchangeable Approaches
Shuyi Sun, Alejandra Ruiz, Sima Pirmoradi, Katia Vega
Abstract
This paper presents BioSparks, a wearable device that detects glucose levels in sweat through electrochemical biosensors crafted with traditional jewelry techniques. Unlike conventional biosensors that are disposed of after use, BioSparks employs a repurposing method, allowing for the reuse of discarded electrodes within the jewelry’s chain, as pendants or earrings. It incorporates interchangeable electrodes that facilitates their replacement after timelife. The modular design enables the wearable to be placed on various body parts, including the neck, wrist and waist. The paper outlines our design considerations for Wearability Factors for Jewelry Biosensors, and the fabrication process combining traditional jewelry techniques and electromistry. Our technical evaluation shows the performance of our biosensor under ten different glucose concentrations.
