  • Patent number: 11406755
    Abstract: An on-body injector includes a drug reservoir with an associated temperature sensor. A piston having an associated force sensor is driven to convey a drug out of the drug reservoir during a drug delivery routine. The temperature and force sensors are electrically coupled to a controller that controls the components of the on-body injector to execute a drug delivery routine. The controller receives signals from the temperature sensor indicative of a temperature of the drug within the reservoir and from the force sensor indicative of a force experienced by the piston during the drug delivery routine. The controller analyzes the signals to determine whether the measured force is different from an expected force at the measured temperature. The controller generates an error signal when the measured force is different from the expected force at the measured temperature.
