Abstract
Described herein are wearable devices and methods for medicament delivery. Example devices can include a housing having an underside adapted to be proximate to a skin surface, and a reservoir disposed in the housing, the reservoir configured to be filled with a medicament to be delivered to the patient. The devices can include a cannula disposed within the housing and coupled to the reservoir, in which the cannula configured to protrude from a port defined by the housing to be positioned in the skin surface. The devices can further include a capacitive sensor configured to detect whether the medicament has leaked from the delivery device, in which the capacitive sensor includes a conductor disposed in a portion of the underside of the housing.
