Printing technologies have been well known for its streamlined steps involved in the production process, better usage of materials, cost effective fabrication and simplified patterning techniques resulting into low cost manufacturing. Over the years, printing technologies has developed various electronic materials compatible with diverse substrates, has led to further expansion of printed electronics into development of printed sensors. Printed sensor are gaining popularity as they provide benefits over conventional silicone sensor such as light weight, thinner size, flexibility, organic materials and low cost, among the others. Glass and plastic are most commonly used substrates and conductive silver ink as well as carbon nanotechnology are among the most widely used inks for development of printed sensors. Moreover, printed biosensors have existed in the market for several years, whereas other printed sensors such as printed temperature, printed image sensors, printed photodetectors, and the others have recently evolved from the R&D into vast applications. These printed sensors are emerging into application areas such as consumer electronics, healthcare, industrial, smart card, and smart packaging, among others.
