While capacitive coupling is known as a parasitic effect, its role in directly activating solid\u2010state devices in open circuits remains underexplored. Here, we demonstrate that externally generated, time\u2010varying electric fields\u2014produced by triboelectric excitation or moving charged objects\u2014can directly activate linear and nonlinear components, such as diodes, rectifiers, and LEDs, without a galvanic connection. A lumped\u2010element capacitive\u2010coupling model captures the observed dependencies\n                    <jats:italic>\n                      V\n                      <jats:sub>ab<\/jats:sub>\n                    <\/jats:italic>\n                    \u221d\u03c9 and\n                    <jats:italic>\n                      V\n                      <jats:sub>ab<\/jats:sub>\n                    <\/jats:italic>\n                    \u221d1\/\n                    <jats:italic>r<\/jats:italic>\n                    , validated experimentally on both linear and non\u2010linear components. The resulting field\u2010driven activation enables energy harvesting in open circuits, multi\u2010channel control, and wireless sensing of human motion and mechanical vibrations over meter\u2010scale distances. This quasi\u2010static capacitive coupling operates in a distinct regime compared to resonant wireless power transfer, because it is drive by low\u2010frequency, motion induced electric field changes that generate transient displacement currents in floating circuits. The findings here enable contact\u2010free activation of electronic components through discrete energy transfer rather than traditional continuous power delivery.\n                  <\/jats:p>","DOI":"10.1002\/advs.75200","type":"journal-article","created":{"date-parts":[[2026,4,7]],"date-time":"2026-04-07T19:30:29Z","timestamp":1775590229000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Field\u2010Driven Activation of Solid\u2010State Devices in Open Circuits for Energy Harvesting and Wireless Sensing"],"prefix":"10.1002","volume":"13","author":[{"given":"Renyun","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Engineering Mathematics and Science Education Mid Sweden University  Sundsvall Sweden"},{"name":"Beijing Institute of Nanoenergy and Nanosystems Chinese Academy of Sciences  Beijing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magnus","family":"Hummelg\u00e5rd","sequence":"additional","affiliation":[{"name":"Department of Engineering Mathematics and Science Education Mid Sweden University  Sundsvall Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henrik","family":"Andersson","sequence":"additional","affiliation":[{"name":"Department of Engineering Mathematics and Science Education Mid Sweden University  Sundsvall Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicklas","family":"Blomquist","sequence":"additional","affiliation":[{"name":"Department of Engineering Mathematics and Science Education Mid Sweden University  Sundsvall Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonas","family":"\u00d6rtegren","sequence":"additional","affiliation":[{"name":"Department of Engineering Mathematics and Science Education Mid Sweden University  Sundsvall Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans\u2010Erik","family":"Nilsson","sequence":"additional","affiliation":[{"name":"Department of Electronic Design Mid Sweden University  Sundsvall Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5530-0380","authenticated-orcid":false,"given":"Zhong Lin","family":"Wang","sequence":"additional","affiliation":[{"name":"Beijing Institute of Nanoenergy and Nanosystems Chinese Academy of Sciences  Beijing People's Republic of China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,4,7]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1587\/transele.2023REP0004"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.coco.2023.101552"},{"key":"e_1_2_9_4_1","article-title":"The Three Quasistatic Limits of the Maxwell Equations","volume":"1909","author":"Kruger S.
