ABSTRACT
Demand for continuous and long term health monitoring has taken the personalized health care from the point-of-care (POC) sensors to wearable biosensors. With growing technological advancements the role of “nano” is becoming dominant for more sensitive, robust, and less intrusive wearable devices and sensors. In this chapter, we present the current state-ofthe art nanoenabled wearable biosensors, in particular the popular strain sensors and electrochemical sensors. Wearable electrochemical sensors are relatively new area of research in the field of wearable sensors which poses unique challenges when compared to physical strain sensors. The challenges, advantages, and the underlying technology of the devices are highlighted. The biggest bottleneck for using the wearable technology is the “energy harvesting”. We summarize the state-of-the-art technologies which are promising solutions to this limitation and discuss the underlying concepts in brief.
