Abstract: A sensor for sensing physiological signal from outside the human body, said sensor comprising an electrode for abutment against the skin; and a transmission conductor electrically connected to said electrode, said transmission conductor formed from a flexible material, wherein in use a substrate is disposed between the skin and said transmission conductor, and said substrate is permeable to moisture and air thereby exposing said transmission conductor to said moisture.

Abstract: A swim monitor comprising a motion sensing device and a controller is provided. The motion sensing device is capable of detecting motion in a plurality of mutually orthogonal axes and the controller is arranged to capture motion data generated by the motion sensing device and to generate swim motion information with reference to the motion data collected. The controller is arranged to generate swim style information with reference to a rhythmic motion pattern detected in at least one selected motion direction. Such a swim monitor provides a compact device for swim monitoring and a simple solution to proved swim style information.
