To address these issues, this study presents a mechanical RF switch with high power capability that uses liquid metals as wetted contacts. It utilizes the rotation of a DC motor, together with a gear-rack meshing drive, to push the movable contact electrode to achieve contact or disconnection with the fixed electrode contacts wetted by eutectic gallium–indium alloy, thus realizing the on/off action of this RF switch. The electrode contacts are made of tin-plated copper, experimentally verified to have good wetting characteristics and low contact resistance with gallium-based liquid metals. For RF performance, small-signal measurements show that the RF switch has a return loss of less than −10 dB, an insertion loss of less than 3.5 dB, and an isolation of more than 13 dB from 0 to 5 GHz, while large-signal measurements suggest that it can handle a maximum power of 45.1 dBm in the 0–3 GHz band.

The device comprises six functional units, each measuring 10 × 10 mm, crafted using a sandwiched structure of paper substrate, graphite, and two PLA films via the hot-pressing technique. Utilizing the corona charging method, the PLA electret films exhibit an impressive piezoelectric coefficient peaking at 3578 pC/N, making it highly sensitive for both sensing and actuating. The pressure sensor, used for writing purposes, demonstrates a sensitivity of 1.01 V/N, while the vibration actuator, used for reading, achieves an output force of 60 mN at an applied voltage of 400 V. Notably, both the surface charge density and the performance of the sensor and actuator stabilize post approximately 1000 interactions. Our psychophysical experiments indicate the device has a perceptible threshold voltage as low as 50 V. Subsequent tactile interaction communication tests offer a preliminary validation of the device’s applicability. The proposed tactile interaction device, being flexibly constructed and intrinsically biodegradable, paves the way for cost-effective tactile communication solutions.</p>","PeriodicalId":3,"journal":{"name":"ACS Applied Electronic Materials","volume":"6 11","pages":"8497–8506 8497–8506"},"PeriodicalIF":4.3,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142719087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
