Abstract: Wearable sensor patches, applicator systems for applying wearable sensor patches, and associated systems, devices, and methods are disclosed herein. In one embodiment, an applicator system includes a first applicator portion, a second applicator portion, a spring, and a trigger mechanism. The first applicator portion releasably retains a wearable sensor patch configured to detect a parameter of an analyte in fluid of a user. When the applicator system is in a loaded mode, the spring and the first applicator portion are positioned within the second applicator portion such that the spring is positioned between the first applicator portion and the second applicator portion. The trigger mechanism is configured to initiate a transition of the applicator system from the loaded mode to a released mode such that the spring accelerates the first applicator portion distally away from the second applicator portion to apply the wearable sensor patch to the user.

Abstract: Biomonitoring systems and methods of loading and releasing the same are disclosed herein. In one embodiment, a biomonitoring system includes a wearable sensor patch and an applicator. The sensor patch has a filament and an electronics subsystem. The sensor patch is configured to detect a parameter of an analyte in fluid of a user when it is adhered to the user's skin and the filament extends into the user's tissue. The applicator includes first and second applicator portions and a spring positioned within an interior of the second application portion between the first and second applicator portions. When the applicator transitions from a loaded mode to a released mode, the spring transitions from a first state of compression to a second, lower state of compression and accelerates the first applicator portion and the wearable sensor patch toward the user's skin such that the filament extends into the user's tissue.
