However, commercially available wearable biomonitoring devices are generally composed of rigid hardware incompatible with the mechanical compliance of soft human tissues. Thin\u2010film stretchable e\u2010skin circuits that can interface the human skin represent an excellent alternative for long\u2010term wearable biomonitoring. Here, a series of soft and stretchable electrodes are evaluated for their applicability in biopotential sensing. This includes conductive composites made of polydimethylsiloxane (PDMS) as a base substrate and conductive particles, i.e., carbon (cPDMS), silver (AgPDMS), anisotropic <jats:italic>z<\/jats:italic>\u2010axis conductors made with silver\u2010coated nickel particles (zPDMS), as well as a combination of a conductive tough hydrogel with PDMS, and finally ultrathin tattoo\u2010like adhesive poly(vinyl alcohol)\u2010coated films with stretchable biphasic Ag\u2010EGaIn electrodes. These electrodes are compared between themselves and against the gold\u2010standard Ag\/AgCl and stainless steel electrodes, in order to assess relative performance in signal\u2010to\u2010noise ratio (SNR) during electrocardiography, and electrode\u2010skin impedance for a range of frequencies. Results show a direct relation between conformity of the electrode\u2013skin interface and the SNR value. An all\u2010integrated biomonitoring patch with embedded processing and communication electronics, hydrogel electrodes, and a multilayer liquid metal circuit is presented for electromyography.<\/jats:p>","DOI":"10.1002\/adhm.201900234","type":"journal-article","created":{"date-parts":[[2019,7,5]],"date-time":"2019-07-05T03:10:49Z","timestamp":1562296249000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":104,"title":["Soft Bioelectronic Stickers: Selection and Evaluation of Skin\u2010Interfacing Electrodes"],"prefix":"10.1002","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5764-2974","authenticated-orcid":false,"given":"Pedro Alhais","family":"Lopes","sequence":"first","affiliation":[{"name":"Soft and Printed Microelectronics Lab Institute of Systems and Robotics University of Coimbra  Coimbra 3030\u2010290 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7343-6636","authenticated-orcid":false,"given":"Davide","family":"Vaz Gomes","sequence":"additional","affiliation":[{"name":"Soft and Printed Microelectronics Lab Institute of Systems and Robotics University of Coimbra  Coimbra 3030\u2010290 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4009-4163","authenticated-orcid":false,"given":"Daniel","family":"Green Marques","sequence":"additional","affiliation":[{"name":"Soft and Printed Microelectronics Lab Institute of Systems and Robotics University of Coimbra  Coimbra 3030\u2010290 Portugal"}]},{"given":"Pedro","family":"Faia","sequence":"additional","affiliation":[{"name":"Soft and Printed Microelectronics Lab Institute of Systems and Robotics University of Coimbra  Coimbra 3030\u2010290 Portugal"}]},{"given":"Joana","family":"G\u00f3is","sequence":"additional","affiliation":[{"name":"CEMMPRE \u2013 Department of Chemical Engineering University of Coimbra  Coimbra 3030\u2010290 Portugal"}]},{"given":"Tatiana F.","family":"Patr\u00edcio","sequence":"additional","affiliation":[{"name":"Soft and Printed Microelectronics Lab Institute of Systems and Robotics University of Coimbra  Coimbra 3030\u2010290 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9351-1704","authenticated-orcid":false,"given":"Jorge","family":"Coelho","sequence":"additional","affiliation":[{"name":"CEMMPRE \u2013 Department of Chemical Engineering University of Coimbra  Coimbra 3030\u2010290 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8664-2757","authenticated-orcid":false,"given":"Arm\u00e9nio","family":"Serra","sequence":"additional","affiliation":[{"name":"CEMMPRE \u2013 Department of Chemical Engineering University of Coimbra  Coimbra 3030\u2010290 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3641-5174","authenticated-orcid":false,"given":"An\u00edbal T.","family":"de Almeida","sequence":"additional","affiliation":[{"name":"Soft and Printed Microelectronics Lab Institute of Systems and Robotics University of Coimbra  Coimbra 3030\u2010290 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6469-9645","authenticated-orcid":false,"given":"Carmel","family":"Majidi","sequence":"additional","affiliation":[{"name":"Integrated Soft Materials Lab Department of Mechanical Engineering Carnegie Mellon University  Pittsburgh PA 15213 USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2590-2196","authenticated-orcid":false,"given":"Mahmoud","family":"Tavakoli","sequence":"additional","affiliation":[{"name":"Soft and Printed Microelectronics Lab Institute of Systems and Robotics University of Coimbra  Coimbra 3030\u2010290 Portugal"}]}],"member":"311","published-online":{"date-parts":[[2019,7,5]]},"reference":[{"key":"e_1_2_7_1_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scispo.2017.03.009"},{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/1941738115616917"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201801852"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/s17010130"},{"key":"e_1_2_7_5_1","first-page":"1","volume-title":"2017 Int.
