Units made from traditional conductive bulk supplies using complex microfabrication strategies often are restricted to being rigid and in some cases, versatile however not strethcable. The primary purpose is the mismatching mechanics between these conventional materials and the elastomeric materials they were bonded with, which causes materials delimination and/or cracks at tender/arduous supplies interfaces beneath strains. Conductive nanomaterials potentially supply new alternative to deal with this problem. Their availability in numerous sizes and shapes enables us to create composites with varied dimensions, comparable to 1D conductive traces, 2D film, and 3D sponge-like architectures. These have opened the door for fabrication of stretchable interconnects, circuits, vitality storage devices, antennas, LEDs, etc. The premise of utilizing conductive nanomaterials composites in sensors is that any stimulus or change will generate a measurable electrical impulse. These impulses may be broadly categorised as piezoelectric, triboelectric, capacitive, and resistive responses. Relying on the sensitivity required and the desire of electrical impulse to be measured, the system development perhaps tailored to present one of the four kinds of electrical responses. Resistive sensors in addition to being the simplest to assemble are also the easiest to measure, which is the crucial cause for a lot of publications on this space. The working mechanism of resistive sensors based mostly on the constituent conductive materials and their percolation network shall be discussed intimately. Composition of conductive inks fabricated utilizing wet chemistry methods, and nanomaterials utilizing dry strategies, their subsequent functions are lined as nicely. The thrilling applications relating to human health and nicely-being will also be described. Finally a short outlook of the future of wearable sensors as "invisibles" shall be presented.
