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.
