Eco-Conscious Approach to Wireless Gas Monitoring: Development of a Hybrid NFC Sensor Tag

Employing advanced functional printing methodologies, an innovative and sustainable sensor solution for wireless gas monitoring is presented. One of its distinguishing features lies in the utilization of a passive near field communication (NFC) chip, negating battery dependency by drawing power from the ambient electric field while transmitting data wirelessly to a read-out device (e.g. smartphone). The sensor tag is mostly fashioned from renewable, biodegradable materials. Moreover, digital additive manufacturing and low temperature processing mark a stride toward eco-friendliness in gas sensing technology.
