Paper-Based Photoconductive Infrared Sensor
The Journal of Physical Chemistry C, 2011We report sensitivity to infrared radiation from a simple paper-made device, which increases its conductivity when exposed to hot objects. We propose that the conductivity of this device is due to ionic currents involving electrolyte salts dissolved in thin film of liquid dispersed over the paper surface, thus the current increases because of heating ...

IEEE Sensors Journal, 2015
In this paper, we report the development of an oxygen sensor using a simple device made from a film of ZnO crystals dispersed over a paper surface. Due to the high porosity of this kind of device made from paper and ZnO, a large photoconductive effect is observed as result of the fast absorption and desorption of oxygen from the ZnO surface.

Colorimetric Paper-based Sensor of As(III)
The novel paper-based colorimetric device using the hydride generation and Au(III) was developed for the determination of As(III) using a smartphone. The analysis of As(III) is based on arsine gas from hydride generation oxidized Au(III) to Au(0). In the presence of As(III), the distinctive color change of the Au(III) from colorless to violet was ...openaire +1 more source
Disintegrating paper-based touch sensors
2016This thesis investigates the disintegrating properties of compacted cellulose-based material used as touch sensors. Pressurized compaction of powdered microcrystalline cellulose (MCC) enabled the fabrication of compacted substrates with quantities ranging from 50 mg to 400 mg and with pressure from 45 to 135 MPa. Along with the quantity of powdered MCC
