چکیده
This letter presents the first solar cell (SC)-powered biofuel (BFC)-input biosensing system with pulse interval modulation (PIM) and density (PDM) LED driving capability for continuous glucose monitoring (CGM) contact lenses featuring stand-alone RF-less operation. Power supply from on-lens SCs can eliminate necessity of wireless power delivery, implementation communication. By employing BFC-input approach instead using a power-hungry potentiostat, powering sensing components are separated, which reduces budget SCs. The measured 28/144 nW at PIM/PDM mode 0.31/0.39-V voltage be managed by SCs, enabling fully operation under office-room ambient light whose typical illumination intensity is 800–1600 lx.

متن کاملA Glucose sensing contact lens: A new approach to non-invasive continuous physiological glucose monitoring
We have developed a new technology for the non-invasive continuous monitoring of tear glucose using a daily use, disposable contact lens, embedded with sugar-sensing boronic acid containing fluorophores. Our findings show that our approach may be suitable for the continuous monitoring of tear glucose levels in the range 50 – 500 μM, which track blood glucose levels that are typically ≈ 5-10 fol...
متن کاملA clinical decision support system for contact lens evaluation
Background: Contact lenses are transparent, thin plastic disks that cover the surface of the cornea. Appropriate lens prescription should be performed properly by an expert to provide better visual acuity and reduce side effects. The lens administration is a multi-stage, complex and time-consuming process involving many considerations. The purpose of this study was to develop a decision support...
