Flexible Substrate-Based Sensors in Health Care and Biosensing Applications

This chapter reviews some of the flexible substrate-based sensor, which includes their fabrication method, materials required for their fabrication, outstanding unique properties of them, and their application in health monitoring. The prepared sensors are attached to the human body which detects human biological signals very quickly and precisely for point care diagnosis. The discovery of this type of sensors has led to the early detection of several deadly diseases like cancers, cardiovascular diseases, and respiratory diseases. Flexible substrate-based sensors are extremely lightweight, transparent, deformable, and stretchable. Flexible sensors made the market of portable, sensitive, inexpensive type of sensors to much famous mainly in the field of clinical application that conventional sensors have become very much obsolete and will get worn-out in the near future. Practical application of this flexible substrate-based sensor is further discussed in this chapter which will give an idea of their expansion in the diagnostic field.
