Bridge connectors employing flexible planar bodies having signal pathways coupling control devices with biometric sensors are disclosed. Sensors are placed in contact with a patient to detect a health condition and generate an output signal based on the health condition. A control device is linked to the sensors to receive the output signal for collection, analysis, storage, display, and/or subsequent transfer. A bridge connector includes a planar body with predetermined flexibility and signal pathways extending between data ports. By removably coupling the bridge connector to the control device and the sensors secured to the patient, the control device may be physically supported by the patient with minimal discomfort and low-cost biometric sensors may be used. In this manner, sensor replacement costs are reduced and the useful lives of the sensors can be maximized as the designed flexibility of the bridge connector facilitates removable coupling with the biometric sensors.
