Since pri nted electronics requires low temperature processing and can handle substr ates of any material and size\, it is compatible with flexible devices as well. According to IDTechEx the total market for printed\, flexible and or ganic electronics will grow from $29.28 billion in 2017 to $73.43 billion in 2027. Gas sensors are one of the important application areas for flexib le printed electronics.\n\nAmong different types of gas sensors acoustic w ave (AW) gas sensors are of great interest. With the advancement in flexib le printed electronics\, researchers have started to fabricate flexible pr inted AW gas sensors as they are low cost\, conformable and have lower fre quency of operation than their rigid microfabricated counterparts. Althoug h these features are attractive\, AW gas sensors developed with flexible p rinted electronics technology by researchers have poor performance. In thi s talk\, the presenter will identify the basic limitations of developing h igh performance flexible printed AW gas sensors\, such as low piezoelectri c charge constants of flexible piezoelectric materials\, poor adhesion bet ween printed conductive layer and flexible substrate and conventional circ uit topologies used. She will present emerging processes\, new materials a nd novel circuit topologies developed at her laboratory to push some of th ese current limitations. She will present some examples of high performanc e flexible printed AW sensors used for volatile organic compounds and carb on dioxide sensing. As gas sensors can play an important role for the grow th of IoT\, this is high time to apply flexible printed electronics in gas sensing area.\n\nSpeaker(s): Dr Sharmistha Bhadra\, \n\nVirtual: https:// events.vtools.ieee.org/m/261755 LOCATION:Virtual: https://events.vtools.ieee.org/m/261755 ORGANIZER:behraad@ieee.org SEQUENCE:11 SUMMARY:Invited Talk: Flexible Printed Acoustic Gas Sensors: A Path Towards Low Cost Sensing (IEEE Sensors Council Chapter) URL;VALUE=URI:https://events.vtools.ieee.org/m/261755 X-ALT-DESC:Description: <br /><p>In recent years\, printed electronics has attracted significant level of interest due to simplified processing steps \, reduced material wastage\, low fabrication cost\, and simple pattering techniques.
