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

USPTO granted patent US12599337B1 to Biolinq Incorporated for a method and system confirming insertion of analyte-selective microneedle sensors into viable tissue via electrical interrogation. The system applies electrical stimulus between electrodes within the sensor array and compares the response to a reference value to determine if insertion was successful. If unsuccessful, the user is instructed to apply additional force or re-apply the sensor. The patent contains 18 claims and covers CPC classifications related to diagnostic sensors and analyte measurement.
Affected parties include medical device manufacturers developing microneedle-based analyte sensors. The patent grants Biolinq exclusive rights to this insertion confirmation technology, which may require licensing for competitors developing similar continuous glucose monitoring or biosensing devices using microneedle arrays.

Abstract
A system and method to confirm the insertion of an analyte-selective sensor comprising an array of microneedles possessing vertical extent between 200 and 2000 μm into viable tissue is disclosed herein. Mechanical insertion of an analyte-selective sensor is firstly attempted by means of an application of external force. Either during or following this routine, an electrical stimulus is applied between at least two distinct electrodes located within the said analyte-selective sensor; a resultant response is measured. This response is compared with a reference value to determine if insertion was successful. If insertion was successful, no further effort is required and the sensor can operate as intended. However, if insertion was not successful, the user can be instructed to continue to apply additional force to said sensor to achieve successful insertion or otherwise re-apply the said sensor altogether.
