Title
(EN) BIOSENSOR EXCITATION METHODS, AND ASSOCIATED SYSTEMS, DEVICES, AND METHODS
Abstract
(EN)

Systems and methods for operating a biosensor are disclosed herein. In some embodiments, the biosensor is configured to access a user's interstitial fluid to determine the concentration of one or more analytes of interest. The method can include applying an excitation voltage to a working electrode of biosensor. The excitation voltage can be a time-varying waveform, such as a square waveform. The method can further include measuring a signal generated by the biosensor and analyzing the signal to determine one or more parameters of the biosensor and/or surrounding environment.
