This study proposes a simple expression to reliable determine resistivity from the concrete electrical resistance (RE) provided by the corrosion sensor of the Integrated Network of Sensors for Smart Corrosion Monitoring (INESSCOM) we have developed. The novelty here is that distinct from common resistivity sensors, the cell constants obtained by the proposed expression are intended to be valid for any sensor implementation scenario. This was ensured by studying most significant geometrical features of the sensor in a wide set of calibration solutions. This embedded-sensor approach is intended to be applicable for RE measurements obtained both using potential step voltammetry (PSV, used in the INESSCOM sensor for corrosion rate measurement) and alternating current methods. In this regard, we present a simple protocol to reliably determine RE, and therefore resistivity, from PSV measurements. It consists in adding a very short potentiostatic pulse to the original technique. In this way, we are able to easy monitor resistivity along with corrosion rate through a single sensor, an advantage which is not usual in structural health monitoring.<\/jats:p>","DOI":"10.3390\/s21072481","type":"journal-article","created":{"date-parts":[[2021,4,2]],"date-time":"2021-04-02T10:34:09Z","timestamp":1617359649000},"page":"2481","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["An Embedded-Sensor Approach for Concrete Resistivity Measurement in On-Site Corrosion Monitoring: Cell Constants Determination"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6765-1735","authenticated-orcid":false,"given":"Jose Enrique","family":"Ram\u00f3n","sequence":"first","affiliation":[{"name":"Instituto de Ciencias de la Construcci\u00f3n Eduardo Torroja, CSIC, C\/Serrano Galvache No.4, 28033 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5729-5124","authenticated-orcid":false,"given":"Isabel","family":"Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Instituto de Ciencias de la Construcci\u00f3n Eduardo Torroja, CSIC, C\/Serrano Galvache No.4, 28033 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0257-3286","authenticated-orcid":false,"given":"Jos\u00e9 Manuel","family":"Gand\u00eda-Romero","sequence":"additional","affiliation":[{"name":"Department of Architectural Construction, Universitat Polit\u00e8cnica de Val\u00e8ncia, Camino de Vera s\/n, 46022 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan","family":"Soto","sequence":"additional","affiliation":[{"name":"Interuniversity Research Institute for Molecular Recognition and Technological Development, Universitat Polit\u00e8cnica de Val\u00e8ncia\u2014Universitat de Val\u00e8ncia, Camino de Vera s\/n, 46022 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Hansson, C.
