Hemerocallis: Smart Jewelry for Mood Monitoring and Healing

This product can detect the user’s emotion in real-time by monitoring their HRV value and carry out emotional healing through aromatherapy. When user’s emotion is abnormal, RGB light in the ring will change color to provide feedback. Then, the wearer can manually rotate the earring to let the fragrant ball emit the aroma of essential oil. I made the prototype by 3D printing the fashion ring and earrings, including PPG sensor, LED feedback, 360-rotation structure and bulges.
