Units made from traditional conductive bulk supplies using advanced microfabrication strategies typically are restricted to being rigid and in some cases, flexible but not strethcable. The principle purpose is the mismatching mechanics between these traditional materials and the elastomeric supplies they had been bonded with, which causes supplies delimination and/or cracks at gentle/laborious supplies interfaces beneath strains. Conductive nanomaterials potentially provide new opportunity to tackle this problem. Their availability in various sizes and shapes enables us to create composites with various dimensions, comparable to 1D conductive traces, 2D film, and 3D sponge-like architectures. These have opened the door for fabrication of stretchable interconnects, circuits, energy storage devices, antennas, LEDs, occupancy sensor installation and so forth. The premise of using conductive nanomaterials composites in sensors is that any stimulus or change will generate a measurable electrical impulse. These impulses may be broadly classified as piezoelectric, triboelectric, capacitive, and resistive responses. Depending on the sensitivity required and the preference of electrical impulse to be measured, the system building perhaps tailor-made to present one of many four kinds of electrical responses. Resistive sensors along with being the best to assemble are additionally the simplest to measure, which is the essential purpose for a lot of publications in this space. The working mechanism of resistive sensors primarily based on the constituent conductive supplies and their percolation community can be discussed in detail. Composition of conductive inks fabricated using wet chemistry methods, and nanomaterials utilizing dry strategies, their subsequent functions are covered as properly. The thrilling applications relating to human health and effectively-being will even be described. Lastly a short outlook of the future of wearable sensors as "invisibles" will be introduced.
