Abstract: A swimming heart rate monitor comprises a strap, a first electrode, a second electrode, a first electrical connector, an electronics module, a second electrical connector, and a water sealing feature. The strap covers a portion of a user's chest. The first and second electrodes are positioned on an inner surface of the strap to contact the user's skin. The electrodes provide an electronic heart signal corresponding to the heartbeat of the user. The first electrical connector is positioned on an outer surface of the strap and is in electronic communication with the first and second electrodes. The electronics module may attach to the strap and process the heart signal. The second electrical connector is accessed on the electronics module and may electrically connect to the first electrical connector. The water sealing feature prevents water from interfering with the connection of the first electrical connector and the second electrical connector.

Abstract: A heart rate monitor (HRM) includes an electrostatic discharge protective layer configured to at least partially shield the heart rate monitor from electrostatic discharge (ESD). The heart rate monitor includes a strap configured to be worn on the body of a user that includes signal and ground electrodes. The signal electrode is configured to receive electrical impulses from the heart of the user, while the ground electrode is configured to electrically ground the heart rate monitor to the body of the user. An electrostatic discharge protective layer is disposed on or in the strap over the signal electrode so that the signal electrode is at least substantially positioned between the body of the user and the electrostatic discharge protective layer when the strap is worn. The electrostatic discharge protective layer is electrically coupled to the ground electrode to at least partially shield the signal electrode from electrostatic discharge.
