The fabrication method, presented here, allows for the development of fully stretchable and wearable sensors. Inkjet-printed sinusoidal and horseshoe patterns are experimentally characterized in terms of the effect of their geometry on stretchability, while maintaining adequate electrical conductivity. The optimal fabricated circuit, with a horseshoe pattern at an angle of 45\u00b0, is capable of undergoing an axial stretch up to a strain of 25% with a resistance under 800 \u2126. The conductivity of the circuit is fully reversible once it is returned to its pre-stretching state. The circuit could also undergo up to 3000 stretching cycles without exhibiting a significant change in its conductivity. In addition, the successful development of a novel inkjet-printed fully stretchable and wearable version of the conventional pulse oximeter is demonstrated. Finally, the resulting sensor is evaluated in comparison to its commercially available counterpart.<\/jats:p>","DOI":"10.3390\/s18103476","type":"journal-article","created":{"date-parts":[[2018,10,16]],"date-time":"2018-10-16T11:07:51Z","timestamp":1539688071000},"page":"3476","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["Experimental Characterization of Inkjet-Printed Stretchable Circuits for Wearable Sensor Applications"],"prefix":"10.3390","volume":"18","author":[{"given":"Jumana","family":"Abu-Khalaf","sequence":"first","affiliation":[{"name":"Department of Mechatronics Engineering\/NanoLab, School of Applied Technical Sciences, German Jordanian University, Amman 11180, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Razan","family":"Saraireh","sequence":"additional","affiliation":[{"name":"Department of Mechatronics Engineering\/NanoLab, School of Applied Technical Sciences, German Jordanian University, Amman 11180, Jordan"},{"name":"Department of Electronics &amp; Communications Engineering, Arab Academy for Science, Technology and Maritime Transport, Cairo 11799, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9304-6048","authenticated-orcid":false,"given":"Saleh","family":"Eisa","sequence":"additional","affiliation":[{"name":"Department of Electronics &amp; Communications Engineering, Arab Academy for Science, Technology and Maritime Transport, Cairo 11799, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ala\u2019aldeen","family":"Al-Halhouli","sequence":"additional","affiliation":[{"name":"Department of Mechatronics Engineering\/NanoLab, School of Applied Technical Sciences, German Jordanian University, Amman 11180, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1109\/JETCAS.2017.2673863","article-title":"A Circuits and Systems Perspective of Organic\/Printed Electronics: Review, Challenges, and Contemporary and Emerging Design Approaches","volume":"7","author":"Chang","year":"2017","journal-title":"IEEE J.
