In this paper, the fabrication of an on-chip interdigitated all-solid-state supercapacitor, using porous gold electrodes and a PVA\/KOH quasisolid electrolyte, is demonstrated. The fabrication of the interdigitated porous gold electrode is performed using an original bottom-up approach. A templating method is used for porosity, using a wet chemistry process followed by microfabrication techniques. This paper reports the first example of an all-gold electrode micro-supercapacitor. The supercapacitor exhibits a specific capacitance equal to 0.28 mF\u00b7cm\u22122 and a specific energy of 0.14 mJ\u00b7cm\u22122. The capacitance value remains stable up to more than 8000 cycles.<\/jats:p>","DOI":"10.3390\/s23020619","type":"journal-article","created":{"date-parts":[[2023,1,5]],"date-time":"2023-01-05T04:51:31Z","timestamp":1672894291000},"page":"619","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["All-Solid-State Interdigitated Micro-Supercapacitors Based on Porous Gold Electrodes"],"prefix":"10.3390","volume":"23","author":[{"given":"Aymeric","family":"Pastre","sequence":"first","affiliation":[{"name":"PhLAM-Physique des Lasers Atomes et Mol\u00e9cules, CNRS, UMR 8523, Universit\u00e9 de Lille, F-59655 Villeneuve d\u2019Ascq, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5499-9273","authenticated-orcid":false,"given":"Alexandre","family":"Bo\u00e9","sequence":"additional","affiliation":[{"name":"IEMN-Institut d\u2019Electronique de Micro\u00e9lectronique et de Nanotechnologie, Universit\u00e9 de Lille, CNRS, UMR 8520, F-59658 Villeneuve d\u2019Ascq, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nathalie","family":"Rolland","sequence":"additional","affiliation":[{"name":"IEMN-Institut d\u2019Electronique de Micro\u00e9lectronique et de Nanotechnologie, Universit\u00e9 de Lille, CNRS, UMR 8520, F-59658 Villeneuve d\u2019Ascq, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1054-5114","authenticated-orcid":false,"given":"R\u00e9my","family":"Bernard","sequence":"additional","affiliation":[{"name":"PhLAM-Physique des Lasers Atomes et Mol\u00e9cules, CNRS, UMR 8523, Universit\u00e9 de Lille, F-59655 Villeneuve d\u2019Ascq, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,5]]},"reference":[{"key":"ref_1","first-page":"77","article-title":"Three dimensional microspercapacitors based on interdigitated patterns of interconnected networks","volume":"21","author":"Omale","year":"2019","journal-title":"Energy Stor.
