▎ 摘  要

NOVELTY - The sensor (1000) has multiple electrodes, a microfluidic channel and an inlet. The inlet is configured to deliver a fluid to the microfluidic channel, and the microfluidic channel is configured to transport the fluid to multiple electrodes. The electrode is set as a laser-induced graphene electrode, and the laser-induced graphene electrode comprises a uniform coating of a metal. The laser-induced graphene electrode comprises second uniform coating of second metal, and the second uniform coating is coated on the uniform coating of the metal. The metal comprises nickel, and the second metal comprises gold. The electrolyte solution comprises sodium hydroxide (NaOH). USE - Non-enzymatic glucose sensor for on body measurement, for daily monitoring and clinical diagnostics for diabetes patient. ADVANTAGE - The non-enzymatic glucose sensor has improved sensitivity for the detection of trace glucose in sweat and other biofluids, and has excellent stability, extended operating duration, and extraordinarily harsh environment tolerance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for forming non-enzymatic glucose sensor. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the non-enzymatic glucose sensor with encapsulated reaction cavity. 100aWorking electrode 100bReference electrode 102Flexible substrate 110Reaction cavity 1000Non-enzymatic glucose sensor
