This paper introduces an analytical model that describes the relation between the external magnetic field and the power efficiency in layered ME composites. It is a two-phase model. The first fragment establishes the expression between the magnetic field strength and the temperature increase within an operating period. It uses a magneto-elasto-electric equivalent circuit model that was developed by Dong et al. Following previous investigations; the main loss source is the mechanical power dissipation. The second fragment links the power efficiency and the temperature increase in a heat-balanced system. This method is generally used by researchers in the piezoelectric field. The analytical model and the experimental data shows that the decrease of the power efficiency in a laminated composite is between 5% and 10% for a power density of 10 W\/in3 (0.61 W\/cm3) to 30 W\/in3 (1.83 W\/cm3). The failure mechanism\/process of ME composites under high power density can be estimated\/monitored by the proposed method for ME composites in practical applications.<\/jats:p>","DOI":"10.3390\/s20113332","type":"journal-article","created":{"date-parts":[[2020,6,15]],"date-time":"2020-06-15T05:56:27Z","timestamp":1592200587000},"page":"3332","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Estimation of the Intrinsic Power Efficiency in Magnetoelectric Laminates Using Temperature Measurements"],"prefix":"10.3390","volume":"20","author":[{"given":"Xin","family":"Zhuang","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, Virginia Tech, Blacksburg, VA 24061, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9164-6955","authenticated-orcid":false,"given":"Chung-Ming","family":"Leung","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Virginia Tech, Blacksburg, VA 24061, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiefang","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Virginia Tech, Blacksburg, VA 24061, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dwight","family":"Viehland","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Virginia Tech, Blacksburg, VA 24061, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3004","DOI":"10.1143\/JJAP.36.3004","article-title":"Influence of temperature rise and vibration level on electromechanical properties of high-power piezoelectric ceramics","volume":"36","author":"Tashiro","year":"1997","journal-title":"Jpn.
