The structural health of pristine and damaged superalloy compressor blades of a gas turbine engine was monitored using real electro-mechanical impedance of deposited thick film piezoelectric transducers at 20 and 200 \u00b0C. IVIUM impedance analyzer was implemented in laboratory conditions for damage detection in superalloy blades, while a custom-architected frequency-domain transceiver circuit was used for semi-field circumstances. Recorded electromechanical impedance signals at 20 and 200 \u00b0C acquired from two piezoelectric wafer active sensors bonded to an aluminum plate, near and far from the damage, were initially utilized for accuracy and reliability verification of the transceiver at temperatures &gt;20 \u00b0C. Damage formation in both the aluminum plate and blades showed a peak shift in the swept frequency along with an increase in the amplitude and number of impedance peaks. The thermal energy at 200 \u00b0C, on the other hand, enforces a further subsequent peak shift in the impedance signal to pristine and damaged parts such that the anti-resonance frequency keeps reducing as the temperature increases. The results obtained from the impedance signals of both piezoelectric wafers and piezo-films, revealed that increasing the temperature somewhat decreased the real impedance amplitude and the number of anti-resonance peaks, which is due to an increase in permittivity and capacitance of piezo-sensors. A trend is also presented for artificial intelligence training purposes to distinguish the effect of the temperature versus damage formation in sample turbine compressor blades. Implementation of such a monitoring system provides a distinct advantage to enhance the safety and functionality of critical aerospace components working at high temperatures subjected to crack, wear, hot-corrosion and erosion.<\/jats:p>","DOI":"10.3390\/s19122805","type":"journal-article","created":{"date-parts":[[2019,6,24]],"date-time":"2019-06-24T02:37:40Z","timestamp":1561343860000},"page":"2805","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Temperature Effects on Electromechanical Response of Deposited Piezoelectric Sensors Used in Structural Health Monitoring of Aerospace Structures"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5717-1351","authenticated-orcid":false,"given":"Hamidreza","family":"Hoshyarmanesh","sequence":"first","affiliation":[{"name":"Project neuroArm, Health Research Innovation Center, University of Calgary, Calgary, AB T2N 4Z6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mojtaba","family":"Ghodsi","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Industrial Engineering, Sultan Qaboos University, Muscat 123, Sultanate of Oman"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minjae","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Yonsei University, Seoul 03722, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyung Hee","family":"Cho","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Yonsei University, Seoul 03722, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5540-5433","authenticated-orcid":false,"given":"Hyung-Ho","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Yonsei University, Seoul 03722, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,6,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Abbas, M., and Shafiee, M.
