A rapid and accurate heart rate measurement is vital during the first minutes after birth. Clinical recommendations suggest that electrocardiogram (ECG) monitoring should be widely adopted in the neonatal intensive care unit to reduce infant mortality and improve long term health outcomes in births that require intervention. Novel non-contact electrocardiogram sensors can reduce the time from birth to heart rate reading as well as providing unobtrusive and continuous monitoring during intervention. In this work we report the design and development of a solution to provide high resolution, real time electrocardiogram data to the clinicians within the delivery room using non-contact electric potential sensors embedded in a neonatal intensive care unit mattress. A real-time high-resolution electrocardiogram acquisition solution based on a low power embedded system was developed and textile embedded electrodes were fabricated and characterised. Proof of concept tests were carried out on simulated and human cardiac signals, producing electrocardiograms suitable for the calculation of heart rate having an accuracy within \u00b11 beat per minute using a test ECG signal, ECG recordings from a human volunteer with a correlation coefficient of ~ 87% proved accurate beat to beat morphology reproduction of the waveform without morphological alterations and a time from application to heart rate display below 6 s. This provides evidence that flexible non-contact textile-based electrodes can be embedded in wearable devices for assisting births through heart rate monitoring and serves as a proof of concept for a complete neonate electrocardiogram monitoring system.<\/jats:p>","DOI":"10.3390\/s21030999","type":"journal-article","created":{"date-parts":[[2021,2,2]],"date-time":"2021-02-02T13:01:12Z","timestamp":1612270872000},"page":"999","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Characterisation of Textile Embedded Electrodes for Use in a Neonatal Smart Mattress Electrocardiography System"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3197-5209","authenticated-orcid":false,"given":"Henry","family":"Dore","sequence":"first","affiliation":[{"name":"Robotics and Mechatronics Systems Research Group, School of Engineering and Informatics, University of Sussex, Brighton BN1 9RH, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo","family":"Aviles-Espinosa","sequence":"additional","affiliation":[{"name":"Robotics and Mechatronics Systems Research Group, School of Engineering and Informatics, University of Sussex, Brighton BN1 9RH, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0766-6174","authenticated-orcid":false,"given":"Zhenhua","family":"Luo","sequence":"additional","affiliation":[{"name":"School of Water, Energy and Environment, Cranfield University, Bedford MK43 0AL, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oana","family":"Anton","sequence":"additional","affiliation":[{"name":"Academic Department of Paediatrics, Royal Alexandra Children\u2019s Hospital Brighton, Brighton BN2 5BE, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heike","family":"Rabe","sequence":"additional","affiliation":[{"name":"Academic Department of Paediatrics, Royal Alexandra Children\u2019s Hospital Brighton, Brighton BN2 5BE, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth","family":"Rendon-Morales","sequence":"additional","affiliation":[{"name":"Robotics and Mechatronics Systems Research Group, School of Engineering and Informatics, University of Sussex, Brighton BN1 9RH, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,2]]},"reference":[{"key":"ref_1","first-page":"S543","article-title":"Part 13: Neonatal Resuscitation","volume":"132","author":"Aziz","year":"2015","journal-title":"Circulation"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Weiner, G.M.Z., Kattwinkel, J., and Ades, A.
