Current devices display limitations that require trade-offs among cortical surface coverage, spatial electrode resolution, aesthetic, and risk consequences and often limit the use of the mapping technology to the operating room. In this work, we report on a scalable technique for the fabrication of large-area soft robotic electrode arrays and their deployment on the cortex through a square-centimeter burr hole using a pressure-driven actuation mechanism called eversion. The deployable system consists of up to six prefolded soft legs, and it is placed subdurally on the cortex using an aqueous pressurized solution and secured to the pedestal on the rim of the small craniotomy. Each leg contains soft, microfabricated electrodes and strain sensors for real-time deployment monitoring. In a proof-of-concept acute surgery, a soft robotic electrode array was successfully deployed on the cortex of a minipig to record sensory cortical activity. This soft robotic neurotechnology opens promising avenues for minimally invasive cortical surgery and applications related to neurological disorders such as motor and sensory deficits.<\/jats:p>","DOI":"10.1126\/scirobotics.add1002","type":"journal-article","created":{"date-parts":[[2023,5,10]],"date-time":"2023-05-10T17:58:38Z","timestamp":1683741518000},"update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":71,"title":["Deployment of an electrocorticography system with a soft robotic actuator"],"prefix":"10.1126","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7754-3578","authenticated-orcid":true,"given":"Sukho","family":"Song","sequence":"first","affiliation":[{"name":"Laboratory for Soft Bioelectronic Interfaces, Neuro-X Institute, \u200cEcole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL), 1202 Geneva, Switzerland."},{"name":"Laboratory of Sustainability Robotics, Swiss Federal Laboratories for Materials Science and Technology (Empa), 8600 D\u00fcbendorf, Switzerland."}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0626-5264","authenticated-orcid":true,"given":"Florian","family":"Fallegger","sequence":"additional","affiliation":[{"name":"Laboratory for Soft Bioelectronic Interfaces, Neuro-X Institute, \u200cEcole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL), 1202 Geneva, Switzerland."}]},{"given":"Alix","family":"Trouillet","sequence":"additional","affiliation":[{"name":"Laboratory for Soft Bioelectronic Interfaces, Neuro-X Institute, \u200cEcole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL), 1202 Geneva, Switzerland."}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5644-8504","authenticated-orcid":true,"given":"Kyungjin","family":"Kim","sequence":"additional","affiliation":[{"name":"Laboratory for Soft Bioelectronic Interfaces, Neuro-X Institute, \u200cEcole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL), 1202 Geneva, Switzerland."},{"name":"Department of Mechanical Engineering, University of Connecticut, Storrs, CT 06269, USA."}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9075-4022","authenticated-orcid":true,"given":"St\u00e9phanie P.","family":"Lacour","sequence":"additional","affiliation":[{"name":"Laboratory for Soft Bioelectronic Interfaces, Neuro-X Institute, \u200cEcole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL), 1202 Geneva, Switzerland."}]}],"member":"221","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"crossref","first-page":"10","DOI":"10.1684\/j.1950-6945.2006.tb00205.x","article-title":"The concept of the epileptogenic zone: A modern look at Penfield and Jasper\u2019s views on the role of interictal spikes","volume":"8","author":"Palmini A.","year":"2006","unstructured":"A.
