Wearable IoT Devices for Health Monitoring

Advances in wearable electronics pave the way for a new class of devices that combine sensing, processing, and communication. These devices enable a wide range of applications including health monitoring, activity tracking, and human-computer interaction. However, three key challenges prevent the widespread use of wearable devices. First, users stop using these devices quickly due to frequent charging requirements. Second, existing wearable devices are bulky and uncomfortable since they are designed using rigid materials. Third, the value of wearable devices has not been demonstrated yet by high-impact applications. This paper presents a set of potential solutions to these three challenges. More specifically, we start with a runtime optimization technique that can enable recharge-free operation. Then, we discuss the design of physically flexible and stretchable devices, which are comfortable to wear. Finally, we review high-impact wearable applications ranging from health monitoring to human-computer interaction.
