1. A device for applying an on-skin sensor assembly to skin of a host, the device comprising:
- a base configured to secure a housing, wherein the housing is configured to receive an electronics unit, wherein the electronics unit is configured to generate analyte information based on a signal from a sensor;
a sensor insertion mechanism configured to insert the sensor into the host; and
a trigger configured, in response to being activated, to cause the sensor insertion mechanism to insert the sensor into the host, to secure the electronics unit to the housing such that the sensor electrically contacts the electronics unit, and to cause the housing to detach from the base.

Abstract
The present embodiments relate generally to systems and methods for measuring an analyte in a host. More particularly, the present embodiments provide sensor applicators and methods of use with pushbutton activation that implant the sensor, withdraw the insertion needle, engage the transmitter with the housing, and disengage the applicator from the housing, all in one smooth motion. Some embodiments contemplate engagement of the transmitter with the housing after release of the applicator.

16. A device for applying an on-skin sensor assembly to skin of a host, the device comprising:
-
a base configured to secure a housing, wherein the housing is configured to receive a transmitter, and the transmitter is configured to generate analyte information based on a signal from a sensor; and a mechanism configured to, in response to a single action by a user, cause the sensor to be inserted into the host, to secure the electronics unit to the housing such that the sensor electrically contacts the electronics unit, and to cause the housing to detach from the base. - View Dependent Claims (17, 18, 19)

20. A device for applying an on-skin sensor assembly to skin of a host, the device comprising:
-
a base configured to secure a housing, wherein the housing is configured to receive an electronics unit, wherein the electronics unit is configured to generate analyte information based on a signal from a sensor; a sensor insertion mechanism configured to insert the sensor into the host, and including a needle carrying the sensor, a rotatable wheel, and a linearly translatable needle carrier; and a trigger configured, in response to being activated, to cause the rotatable wheel to rotate, which in turn causes the linearly translatable needle carrier to translate toward the host to implant the sensor, and subsequently to translate away from the host to withdraw the needle from the host.
