This microfluidic approach, based on printed circuit board technology, allows large area processing of large cross section conductors and robust contacts, which can handle  a lot of stretching between the embedded rigid active components and the surrounding system. Although it provides such benefits, further development is needed to realize its potential as a high throughput, cost-effective process technology. In this paper,  tape transfer printing is proposed to supply a rapid prototyping batch process at low cost, albeit at a low resolution of 150 \u03bcm. In particular, isolated patterns can be obtained in  a simple one-step process. Finally, a stretchable radio frequency identification (RFID) tag is demonstrated. The measured results show the robustness of the hybrid integrated system when the tag is stretched at 50% for 3000 cycles.<\/jats:p>","DOI":"10.3390\/s140916311","type":"journal-article","created":{"date-parts":[[2014,9,3]],"date-time":"2014-09-03T11:04:54Z","timestamp":1409742294000},"page":"16311-16321","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":61,"title":["Tape Transfer Printing of a Liquid Metal Alloy for Stretchable RF Electronics"],"prefix":"10.3390","volume":"14","author":[{"given":"Seung","family":"Jeong","sequence":"first","affiliation":[{"name":"The Angstrom Laboratory, Department of Engineering Sciences, Uppsala University, Box 534, Uppsala 75121, Sweden"}]},{"given":"Klas","family":"Hjort","sequence":"additional","affiliation":[{"name":"The Angstrom Laboratory, Department of Engineering Sciences, Uppsala University, Box 534, Uppsala 75121, Sweden"}]},{"given":"Zhigang","family":"Wu","sequence":"additional","affiliation":[{"name":"The Angstrom Laboratory, Department of Engineering Sciences, Uppsala University, Box 534, Uppsala 75121, Sweden"},{"name":"State Key Laboratory of Digital Manufacturing Equipment and Technology, Huazhong University of Science and Technology, Wuhan 430074, China"}]}],"member":"1968","published-online":{"date-parts":[[2014,9,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1603","DOI":"10.1126\/science.1182383","article-title":"Materials and mechanics for stretchable electronics","volume":"327","author":"Rogers","year":"2010","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"316","DOI":"10.1038\/nmat2971","article-title":"et al.
