This review focuses on the advances in mechanical antennas, potential applications as well as challenges and potential future directions for further performance improvement. Although the sizes of the state-of-the-art mechanical antennas are several orders of magnitude smaller than traditional electrical counterparts with the same resonant frequencies, the reported maximum operation distance of mechanical antennas is still short, which is a major challenge for it to be widely implemented. By adopting new materials for mechanical antennas, adopting array configurations, adopting receiving antennas with higher sensitivity, and building new electromagnetic-electromechanical coupled simulation methods, the maximum operation distance may be significantly improved, making mechanical antennas widely implemented in the Internet of Things (IoT), wireless sensor networks (WSN), implantable medical devices (IMD), and portable electronics applications.</p>","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202400074","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
