The work focuses on harvesting energy from a 13.56 MHz NFC field to power an ultra-low power sensing platform. The design consists of the TI RF430FRL152H, an integrated NFC transponder with an embedded MSP430 microcontroller core and ferroelectric random-access memory (FRAM) non-volatile memory. The system combines an ISO\/IEC 15693 NFC front end, a tuned loop antenna for optimized power harvesting, and multiple analog and digital sensor interfaces, and a firmware architecture for intermittent harvested energy operation. The aforementioned design performs on-demand data acquisition, logs measurements in the FRAM, and communicates the measured results through an ISO15693 compliant NFC link while powered entirely by the reader\u2019s radio-frequency (RF) field. Since NFC provides only limited harvested power, efficient energy management is critical. The proposed scheme continuously monitors the storage capacitor voltage and activates each sensor only when sufficient energy is available. After every measurement, the system reassesses the stored charge before triggering the next acquisition, ensuring stable multi-sensor operation. A BMP390 temperature and pressure sensor and the on-chip temperature sensor demonstrate the platform\u2019s capability. Experimental results show that the system harvests 1.064 mW (1.85 V, 560 \u00b5A), achieves a wireless operating range of up to 40 mm, and delivers a response time of 800 ms, demonstrating its suitability for low-power temperature and pressure sensing applications.<\/jats:p>","DOI":"10.3390\/jsan15030042","type":"journal-article","created":{"date-parts":[[2026,5,26]],"date-time":"2026-05-26T13:28:21Z","timestamp":1779802101000},"page":"42","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Near-Field Communication (NFC) Multi-Sensor Node with Optimized Read Range and Adaptive Power Management for Remote Monitoring"],"prefix":"10.3390","volume":"15","author":[{"given":"Rishin","family":"Patra","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, Michigan Technological University, Houghton, MI 49931, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3159-1961","authenticated-orcid":false,"given":"Hilary Scott Nkimbeng","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Michigan Technological University, Houghton, MI 49931, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9210-9681","authenticated-orcid":false,"given":"Jin W.","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Michigan Technological University, Houghton, MI 49931, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"111291","DOI":"10.1016\/j.rse.2019.111291","article-title":"Remote sensing for drought monitoring and impact assessment: Progress, past challenges and future opportunities","volume":"232","author":"West","year":"2019","journal-title":"Remote Sens.
