NFC Sensing of Tear Fluid for Animal health Monitoring

This article describes the state-of-the-art and preliminary Electromagnetic (EM) simulations related to the design of a contact lens for health monitoring of cattle or other animals. This project is part of the SFI center Vistamilk as part of the work program associated with the "Cow cluster" which is focused on research in the Dairy industry sector. In this article, we propose to use NFC (Near-Field Communication) technology to be integrated in a contact lens to measure biomarkers in the tear fluid of a cow's eye for health monitoring. The feasibility of such an approach is described and documented. The EM simulations described show that the design of a contact lens for cows, with integrated sensing capability, is feasible and will inform future research in this area in the implementation of such a system.
