This data was collected from the labs of Device Materials Group, Department of Materials Science and Metallurgy, University of Cambridge, between Dec 2016 to Jan 2019. The data contains resistance values measured from the printed device at various conditions such as stretching, fatigue test or different composite. The data also contains profile value of the thickness of the printed device. There are also current and voltage measurements on the LED during lighten up with the printed wire, as well as various capacitance data when the devices were applied as humidity sensor.
