▎ 摘  要

NOVELTY - The system has a bionic micro-flow channel sample collecting module for collecting tear liquid. The bionic micro-flow channel sample collecting module isolates a tear glucose monitoring sensor i.e. graphene sensor to outside to reduce interference, where the tear glucose monitoring sensor is used for detecting a glucose content in a tear fluid. The tear glucose monitoring sensor is connected with the bionic micro-flow channel sample collecting module. A wireless signal transmission module is connected with the tear glucose monitoring sensor. A contact lens outer circuit module receives detection result signal transmitted by the wireless signal transmission module. The bionic micro-flow channel sample collecting module, the tear glucose monitoring sensor and the wireless signal transmission module are placed on the substrate, where the substrate is made of a flexible transparent material. A receiving terminal comprises a mobile phone, a computer or an oscillograph. USE - Contact lens type tear glucose sensing monitoring system for use in a biological medical appliance field. ADVANTAGE - The bionic micro-flow channel sample collecting module, the tear glucose monitoring sensor and the wireless signal transmission module are placed on the substrate, thus improving security, comfort and portability of eye physiological information monitoring. The contact lens outer circuit module receives the detection result signal transmitted by the wireless transmission module so as to realize continuous non-invasive glucose monitoring purpose, thus combining correlation of tear and blood components in an effective manner.
