However, most of these wireless sensor tags have been used for single-sensing applications. In this study, we designed a printed circuit board (PCB) module (13 mm \u00d7 13 mm) for near-field communication-enabled sensor tags with both electrical resistance and capacitance read-out channels that enables dual-channel sensing. As part of the wireless sensor tag, a square antenna pattern was printed directly on a flexible poly(ethylene terephthalate) (PET) substrate and integrated into the PCB module to demonstrate a dual-channel temperature and ethylene gas sensor. The temperature and ethylene sensors were printed using a positive temperature coefficient ink and a tin oxide (SnO2) nanoparticle ink, respectively. With dual sensing capabilities, this type of sensor tag can be used in smart packaging for the quality monitoring of fresh produce (e.g., bananas) by tracking temperature and ethylene concentration in the storage\/transport environment.<\/jats:p>","DOI":"10.3390\/s23156765","type":"journal-article","created":{"date-parts":[[2023,7,31]],"date-time":"2023-07-31T02:13:32Z","timestamp":1690769612000},"page":"6765","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["NFC-Enabled Dual-Channel Flexible Printed Sensor Tag"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8328-4082","authenticated-orcid":false,"given":"Jonghyun","family":"Choi","sequence":"first","affiliation":[{"name":"The New Zealand Institute for Plant and Food Research Ltd., Private Bag 3230, Waikato Mail Centre, Hamilton 3240, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ian","family":"Visagie","sequence":"additional","affiliation":[{"name":"The New Zealand Institute for Plant and Food Research Ltd., Private Bag 3230, Waikato Mail Centre, Hamilton 3240, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Chen","sequence":"additional","affiliation":[{"name":"Scion, New Zealand Forest Research Institute Ltd., T\u012btokorangi Drive, Private Bag 3020, Rotorua 3046, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2273-2216","authenticated-orcid":false,"given":"Robert","family":"Abbel","sequence":"additional","affiliation":[{"name":"Scion, New Zealand Forest Research Institute Ltd., T\u012btokorangi Drive, Private Bag 3020, Rotorua 3046, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kate","family":"Parker","sequence":"additional","affiliation":[{"name":"Scion, New Zealand Forest Research Institute Ltd., T\u012btokorangi Drive, Private Bag 3020, Rotorua 3046, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"286","DOI":"10.1038\/s41578-021-00299-8","article-title":"The future of near-field communication-based wireless sensing","volume":"6","author":"Olenik","year":"2021","journal-title":"Nat.
