Printed electronics represents a major departure from conventional manufacture of electrical and electronic components, such as silicon chips, by making possible the production of lightweight, flexible electronic devices on synthetic substrates. Ryedale Group are using a grant from Yorkshire Forward to commence work on a project for completion by end March 2011. The project is to produce a functional solid-state electrochemical ammonia sensor onto plastic substrates. This has potential for recognising when food goes off, and also potentially for assessing dialysis patients by monitoring their breath.This is cutting edge technology with a very steep learning curve, but a fantastic amount of knowledge will be gained. The process will be unique, the technology is truly innovative, and the exploration into what other opportunities are available at the forefront of this technology will be an interesting journey.
