▎ 摘　　要

NOVELTY - Battery-powered analyte sensing system comprises a printed battery comprising an anode that comprises a non-toxic biocompatible metal; a first carbon-based current collector in electrical contact with the anode; a three-dimensional hierarchical mesoporous carbon-based cathode; a second carbon-based current collector; and an electrolyte layer arranged between the anode and the cathode, the electrolyte layer configured to activate the printed battery when the electrolyte is released into one or both the anode and the cathode; and an analyte sensor comprising a sensing material; and a reactive chemistry additive in the sensing material. USE - Battery-powered analyte sensing system used in Three-dimensional (3D) printing techniques. ADVANTAGE - The battery-powered analyte sensing system has mutli-portion and non-toxic biocompatible metal. The 3D hierarchical mesoporous carbon-based cathode having an open porous structure for gas diffusion with areas to catalyze active material reduction comprising oxygen and other gaseous species, the reduced oxygen creating water upon exposure to ambient air, the open porous structure for active water management. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a battery, which comprises a first current collector comprising a cathode comprising a first scaffold mesoporous carbon-based material; a second current collector comprising an anode comprising a second scaffold mesoporous carbon-based material, the first and second current collectors positioned opposite to each other; and a layer of electrolyte beads arranged between the first and second current collectors, the electrolyte beads configured to remain in a dormant state until released into one or both the anode and the cathode based in portion on pressure applied to the electrolyte beads.
