A contact lens with embedded sensor for monitoring tear glucose level
TL;DR: The design, construction, and testing of a contact lens with an integrated amperometric glucose sensor is reported, proposing the possibility of in situ human health monitoring simply by wearing a contact eye, with good linearity for the typical range of glucose concentrations in the tear film.
Journal ArticleDOI
A 3- $\mu\hbox{W}$ CMOS Glucose Sensor for Wireless Contact-Lens Tear Glucose Monitoring
TL;DR: A noninvasive wireless sensor platform for continuous health monitoring that is wirelessly powered and achieves a measured glucose range of 0.05-1 mM with a sensitivity of 400 Hz/mM while consuming 3 μW from a regulated 1.2-V supply is presented.
Patent
Wireless powered contact lens with glucose sensor
TL;DR: In this paper, a contact lens with an integrated glucose sensor is presented, which includes an electrochemical sensor configured to measure the level of glucose in the tear fluid of the eye of the user wearing the contact lens.
Journal ArticleDOI
A contact lens with integrated telecommunication circuit and sensors for wireless and continuous tear glucose monitoring
Huanfen Yao,Yu-Te Liao,Andrew Lingley,A. Afanasiev,Ilkka Lähdesmäki,Brian Otis,Babak A. Parviz +6 more
TL;DR: An integrated functional contact lens, composed of a differential glucose sensor module, metal interconnects, sensor read-out circuit, antenna and telecommunication circuit, to monitor tear glucose levels wirelessly, continuously and non-invasively is presented.
Proceedings ArticleDOI
A 3μW wirelessly powered CMOS glucose sensor for an active contact lens
TL;DR: Non-invasive sensing would allow a painless, convenient solution compared to traditional skin-piercing glucose meters and integrate sensors into a contact lens would provide a way to continuously and reliably sense metabolites in tear fluids.
