Abstract
Systems and methods for monitoring eyedrop usage are disclosed. Example embodiments include a system to monitor eyedrop usage. The system may include a detection and activation circuit couplable to a wireless biosensor and an eyedrop dispenser. The detection and activation circuit may include a pressure transducer that transmits a signal upon detecting a force at, or above, a threshold value. The system may also include a wireless biosensor insertable into a region of an eyelid. The wireless biosensor may include a sensor to detect the physical change and the chemical change of tears as a result of eyedrop usage. The wireless biosensor may also include a transceiver to receive the signal that activates the sensor for an activation time.
