Dual-Function Hydrogel-Based Smart Wearables: AI-Driven Temperature Responsiveness & UV Index-Indicative Color Monitoring

The integration of smart wearable technology with daily life necessitates materials that are not only responsive but also robust and user-friendly. This work introduces an advancement in smart wearables crafted from hydrogel composites, employing Digital Light Processing (DLP) 3D printing to achieve a level of durability comparable to conventional plastics. The enhanced hydrogels uniquely incorporate thermochromic & photochromic capabilities, allowing for a dynamic color response to temperature & UV light variations.<br/>These color transitions are not merely aesthetic; they are intricately linked to an artificial intelligence (AI) model specifically trained to decode these hues into precise temperature measurements, providing a non-invasive method for monitoring personal thermal environments. In contrast, the photochromic aspect of the wearables acts as a visual sentinel against UV exposure, autonomously signaling when protective measures are advisable, bypassing the need for AI intervention.<br/>These transformative hydrogel wearables challenge existing perceptions of material capabilities. With direct colorimetric feedback for UV protection and AI-assisted temperature monitoring, they offer practical, immediate environmental responsiveness in a user-friendly format.
