A novel wireless tear glucose level sensor system for diabetes patients is presented. The concept provides a miniaturized sensor that can be worn non-invasively under the eye lid. It is composed of a chronoamperometric glucose sensor and an ASIC set with integrated potentiostat and transponder circuits. Wireless energy and data transmission according to the passive transponder standard ISO18000-3 is used to power and readout the sensor by a reader unit. The special coil shape design of the sensor unit enables adoption to the shape of an eye whilst and hence high comfort for the patient. High integration level is achieved by a combination of antenna and sensor electrode wires.
