Paper-based field-effect transistor sensors

Talanta, 2022
The present scenario in the world largely demands affordable, fast, recyclable, and flexible electronic devices for bio sensing. Varieties of paper-based devices such as microfluidics paper electrodes, paper diodes, and paper-based transistors etc. have been developed and validated.

Paper‐Based Active Tactile Sensor Array

Advanced Materials, 2015
A paper-based active tactile sensor -array (PATSA) with a dynamic sensitivity of 0.35 V N(-1) is demonstrated. The pixel position of the PATSA can be routed by analyzing the real-time recording voltages in the pressing process. The PATSA performance, which remains functional when removing partial areas, reveals that the device has a potential ...

Paper-Based Ion-Selective Potentiometric Sensors

Analytical Chemistry, 2012
A new approach to develop ultra low-cost, robust, rugged, and disposable potentiometric sensors is presented. A suspension of carbon nanotubes in a water-surfactant mixture (carbon nanotubes ink) is applied on conventional filter papers to turn them into conductive papers, which are then used as a substrate to build ion-selective electrodes.

Towards paper based diaper sensors

2015 IEEE Biomedical Circuits and Systems Conference (BioCAS), 2015
This paper presents our initial efforts towards the development of screen printed sensors on folded paper substrates for multi-modal sensing of biopotentials, wetness, and pressure. These sensors contain three layers of sensing stripes forming a 16-pixel array where various layers are utilized for different sensing modalities.

Paper-based capacitive mass sensor

2011 IEEE SENSORS Proceedings, 2011
Paper-based MEMS is a new area in the field of micro-electro mechanical systems. We have developed a paper-based MEMS sensing device that is capable of measuring masses as small as 2mg (∼20µN) with a sensitivity of 0.5fF/mg. Using this device, we monitored changes in capacitance values, which can be related to mass changes.
