Microneedle Electrical Interface Patent Granted to Biolinq

The USPTO granted Patent US12605100B2 to Biolinq Incorporated on April 21, 2026, covering methods for achieving an isolated electrical interface between an anterior surface of a microneedle structure and a posterior surface of a support structure. The patent describes a microneedle-based electrochemical biosensor structure comprising a substrate, microneedle biosensor, primary and secondary electrically conductive elements, and an electrically insulative annular barrier. The patent application (No. 19258472) was filed July 2, 2025, and contains 26 claims.

Method and System for Confirmation of Microneedle-Based Analyte-Selective Sensor Insertion via Electrical Interrogation

USPTO granted patent US12599337B1 to Biolinq Incorporated on April 14, 2026, covering a system and method for confirming microneedle sensor insertion into viable tissue using electrical interrogation. The invention applies electrical stimulus between electrodes within an analyte-selective sensor array (200-2000 μm vertical extent) to measure a response and compare it against a reference value to determine insertion success. If insertion fails, the user is instructed to apply additional force or re-apply the sensor.
