P1.8.6 All-additive Inkjet Printed Humidity and Temperature Sensors Fabricated and Encapsulated at Foil Level

F. Molina-Lopez, A. Vásquez Quintero, G. Mattana, D. Briand & N. F. De Rooij
We present the simultaneous fabrication at foil level of ambient relative humidity (R.H.) and temperature sensors printed on flexible substrate. These sensors are based on capacitors and resistors and their combination allows the compensation of the R.H. signals variations at different temperatures. The whole fabrication of the system is carried out at foil level and involves the utilization of additive methods, namely inkjet printing and electrodeposition, as well as the final encapsulation of the sensors...
