Abstract
The present technology relates to intracardiac sensors and associated systems and methods. In some embodiments, the present technology includes a device for monitoring pressure within a patient's heart. The device can include an implantable capacitor having a capacitance value that is variable based on the pressure within the patients heart and a sensing circuit configured to measure the capacitance value. The device can also include an implantable inductor and a power circuit configured to wirelessly receive power from an external source via the inductor. When the device is in a first configuration, the capacitor can be electrically coupled to the sensing circuit and the inductor can be electrically coupled to the power circuit. When the device is in a second configuration, the capacitor can be electrically coupled to the inductor to form a resonant circuit.
