Techniques for conduction-based contact detection for physiological sensors are described. In an example, a wearable device includes a contact-based sensor configured to collect physiological data of a user and at least one electrode positioned proximate to the contact-based sensor, such that a contact status of the electrode corresponds to a contact status of the sensor. The wearable device includes a contact detection circuit that is configured to determine a contact condition of the contact-based sensor that indicates whether the sensor is in sufficient contact with the skin surface based on an electrical characteristic of a conduction path between the at least one electrode and a skin surface of the user. In this way, the techniques described herein support reliable detection of sensor contact quality through conduction-based measurements, which enables wearable devices to ensure accurate physiological data collection while optimizing power consumption and improving an overall user experience.
