Body temperature is a crucial parameter in healthcare diagnosis. In gynecology and obstetrics it is measured at the skin\u2019s surface, which is very influenced by the environment. This paper proposes a new intra-body sensor for long-term intra-vaginal temperature collection. The embedded IEEE 802.15.4 communication module allows the integration of this sensor in a Wireless Sensor Network (WSN) for remote data access and monitoring. We present the sensor architecture, the construction of the corresponding testbed, and its performance evaluation. This sensor may be used in different medical applications, including preterm labor prevention and fertility and ovulation period detection. The features of the constructed testbed were validated in laboratory tests verifying its accuracy and performance.<\/jats:p>","DOI":"10.3390\/s101110314","type":"journal-article","created":{"date-parts":[[2010,11,17]],"date-time":"2010-11-17T11:34:35Z","timestamp":1289993675000},"page":"10314-10327","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["A New Wireless Biosensor for Intra-Vaginal Temperature Monitoring"],"prefix":"10.3390","volume":"10","author":[{"given":"Jo\u00e3o M.
