The proposed SCL system integrated with 3D technology is composed of tunable sensitivity sensor-readout circuitry, a tear sensor, and an antenna, and is embedded into a biocompatible hydrogel-based contact lens by a commercial manufacturing process. Moreover, the on-lens system can be addressed using commercial radio-frequency identification (RFID) reader devices for sensor control and data communication. Subjects can wear the SCL for continuous tear-content monitoring. Furthermore, the recordings from the device can provide high distinguishability in different tear phantoms using a variation of capacitance or resistance rather than using the weight loss.","PeriodicalId":333275,"journal":{"name":"2017 Symposium on VLSI Technology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126035379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed method can generate minimum pulse width of 100ps stress waveform through on-die tunable pulse-width generator and time-to-current duty detector circuits. The silicon data first demonstrated Cu critical peak current will enter the adiabatic regime under 100ps pulse width with 10X peak current than in thermal diffusion regime.
