The vacuum industry relies on accurate pressure measurement and control. A new compact wireless vacuum sensor was designed and simulated and is presented in this publication. The sensor combines the Pirani principle and Surface Acoustic Waves, and it extends the vacuum sensed range to between 10\u22124 Pa and 105 Pa all along a complete wireless operation. A thermal analysis was performed based on gas kinetic theory, aiming to optimize the thermal conductivity and the Knudsen regime of the device. Theoretical analysis and simulation allowed designing the structure of the sensor and its dimensions to ensure the highest sensitivity through the whole sensing range and to build a model that simulates the behavior of the sensor under vacuum. A completely new design and a model simulating the behavior of the sensor from high vacuum to atmospheric pressure were established.<\/jats:p>","DOI":"10.3390\/s19102421","type":"journal-article","created":{"date-parts":[[2019,5,27]],"date-time":"2019-05-27T11:19:27Z","timestamp":1558955967000},"page":"2421","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Design and Simulation of a Wireless SAW\u2013Pirani Sensor with Extended Range and Sensitivity"],"prefix":"10.3390","volume":"19","author":[{"given":"Sofia","family":"Toto","sequence":"first","affiliation":[{"name":"Institute of Microstructure Technology, Karlsruhe Institute of Technology, Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0575-1079","authenticated-orcid":false,"given":"Pascal","family":"Nicolay","sequence":"additional","affiliation":[{"name":"Carinthia Institute for Smart Materials and Manufacturing Technologies (CiSMAT), Carinthia University of Applied Sciences, 9524 Villach\/St. Magdalen, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4881-4623","authenticated-orcid":false,"given":"Gian Luca","family":"Morini","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria Industriale, Alma Mater Studiorum Universit\u00e0 di Bologna, Viale Risorgimento 2, I-40136 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Rapp","sequence":"additional","affiliation":[{"name":"Institute of Microstructure Technology, Karlsruhe Institute of Technology, Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4354-7295","authenticated-orcid":false,"given":"Jan G.","family":"Korvink","sequence":"additional","affiliation":[{"name":"Institute of Microstructure Technology, Karlsruhe Institute of Technology, Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7018-2338","authenticated-orcid":false,"given":"Juergen J.","family":"Brandner","sequence":"additional","affiliation":[{"name":"Institute of Microstructure Technology, Karlsruhe Institute of Technology, Hermann-von-Helmholtz-Platz 1, 76344 Eggenstein-Leopoldshafen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,27]]},"reference":[{"key":"ref_1","first-page":"1743","article-title":"Theory and design for mechanical measurements","volume":"12","author":"Figliola","year":"1996","journal-title":"Meas.
