Abstract
Paper-based devices are particular of interest due to their unique properties including low-cost, flexibility, light weight and environmental-friendliness. However, till now the number of developed paper-based electronic devices has been limited. Here, a paper-based piezoresistive pressure sensor has been developed. In the fabrication process, graphite piezoresistors were fabricated on a paper substrate by an inkjet-printed water mask method and assembled onto a polystyrene base. The sensitivity of the developed pressure sensor was found to be 20.0 μV/V/mmHg in a range of pressures from 0 to 65.26 mmHg. A comparison with a commercial silicon-based sensor reveals a great potential for paper-based sensors to be alternatives to silicon-based sensors.
