Printed Wireless Humidity Sensors for Moisture Detection in Buildings (Printed Electronics Europe 2013)

• We present a humidity sensor label that is fully printed on a flexible substrate with a R2R-patterned antenna

• The label is passive and can be read out from inside a wall, using a dedicated reader

• The presentation will describe principle of operation, manufacturing issues, and possible user scenarios.

 

The sensor labels have been developed in a joint project between Linköping University, Acreo AB, and some other participants.

Isak Engquist is a senior lecturer in Organic Electronics at Linköping University, Sweden. He received his PhD in Applied Physics at Linköping University in 1996, then worked as a research scientist at the Swedish Defence Research Agency and as a senior researcher at Thin Film Electronics AB, before joining the University in 2007. His current research activities include printed organic transistors and sensor circuits. He has published 22 papers in scientific journals and is a co-inventor of 7 patents.
