AURA

A Bracelet for Skin Protection via UV and Cancer Detection

Abstract

AURA is a wearable 3D-printed bracelet designed for both UV protection and early skin cancer detection. It integrates real-time UV monitoring, electrical impedance spectroscopy (EIS)-based lesion assessment, and AI-powered mole detection and classification in a compact, offline device. A UV analog sensor measures UV index, while the AD5933 chip enables impedance analysis of skin abnormalities. A CoreML model classifies moles from user-taken images with on-device AI. Paired with a mobile app via Bluetooth Low Energy, AURA empowers users to monitor UV exposure, evaluate lesions, and detect suspicious moles, combining prevention with accessible, early diagnosis.

Hardware

The Bracelet

UV Monitoring & Alerts – The bracelet uses a UV sensor and RGB LED to indicate real-time UV risk levels.
Skin Cancer Detection – Integrates miniaturized Electrical Impedance Spectroscopy (EIS), a clinically validated method with up to 90% accuracy in detecting abnormal skin tissue.
Wearable Innovation – Built around the ESP32-S3 and AD5933 chip, AURA is the first battery-powered bracelet to combine UV sensing with portable EIS-based lesion analysis.
