Several industrial, automotive, and healthcare applications rely on accurate and precise measurement of pressure. Flexible and wearable pressure sensors are typically fabricated using petroleum-based polymers, but the solid waste generated from using such non-biodegradable plastics is harmful for the environment. To avoid this issue, researchers at the Indian Institute of Science (IISc.) have now fabricated pressure sensors that use paper as the medium.
According to an IISc. release, a pressure sensor detects physical pressure and converts it into an electrical signal that is displayed in the form of a number indicative of its magnitude.
Nowadays, paper-based electronic devices are gaining greater attention owing to their natural biodegradability, excellent flexibility, porous fibrous structure, light weight, and low cost. However, paper-based sensors developed so far have certain disadvantages.
