SMArt Bracelet: On-Skin interface for user-regulated breathing and stress management

In this paper, we present SMArt bracelet, a smart on-skin wearable interface integrated with Shape-Memory Alloy (SMA) springs that is aimed to promote well-being of individuals by allowing self-regulation of stress and anxiety using mindful breathing practices. The SMArt bracelet comprises a woven band with elastic which can be customized for aesthetics and integrated with hardware that allows the bracelet to be programmed to react to elevated stress and anxiety levels of the user. An increase in heart rate triggers the bracelet, offering visual and haptic feedback to remind them to regulate their breathing. Integration of the hardware in the soft woven fabric is the main challenge, but the potential benefits of the on-skin interface in health monitoring and improved well-being present opportunities for further exploration.
