Printed Gas Sensors Workshop

Printed Gas Sensors: Exploring the Applications

On February 9th, we held an industry consultation workshop to report the results achieved on printed gas sensors by the iPESS project (integration of Printed Electronics with Sensors and Silicon).

The team at the University of Manchester led by Professors Mike Turner and Krishna Persaud has successfully developed unique technology for sensing volatile compounds, based on printed gas-sensitive organic semiconductors in a low-voltage field-effect transistor array architecture fabricated on plastic film substrates.

Demonstrator: A model train carrying a bottle of alcohol is passing through a tunnel. The air in the tunnel is being sampled by a pump to the sensor which causes a real-time change in the electrical current of the OFETs due to the exposure to alcohol vapour. The transient response is monitored continuously on a laptop. The printed OFET sensing array is also shown in the picture.  Watch video

The array uses different organic semiconductors that help to sense and differentiate between various gaseous compounds. Palm-size electronics record the change in sensor parameters and then relay signals to a laptop via USB.

In addition to high sensitivity towards VOCs and other toxic gasses such as ammonia, the array operates at room temperature using low voltages (<3 V), which make it attractive for low-cost and low-power gas sensing applications. 

This workshop was an excellent opportunity for the EPSRC Centre members to obtain guidance on the future direction of the project from UK experts in different fields. The project team is seeking to  address real challenges with their printed gas sensor technology and system integration capability to enable the manufacture of pervasive, cost effective and accurate detectors for gases such as ammonia, methane etc.

14 companies participated in the workshop, representing the UK industrial community in the field of gas sensors covering the whole value chain from device manufacturers to system integrators and end-users in different sectors, such as the healthcare, consumer, automotive, defence and built environment market sectors.

Following a series of presentations from the EPSRC Centre, there was a live demonstration of the technology, a panel discussion, open networking and one-to-one discussion sessions with the project team to explore potential applications of interest. More about the integration of printed electronics with silicon for smart sensor systems (iPESS) in this presentation.

This is the third event of this kind for the EPSRC Centre (following events on energy harvesting and on design for testability) and we will organize further consultation workshops in the future to share more of the compelling results achieved by our research teams.

We encourage companies interested in attending future consultations and wanting to know more about the progress of our projects to contact:
