    • A wearable article (1) including a sensor assembly (104) for sensing signals, such as biosignals, that are associated with a wearer of the wearable article. The sensor assembly comprises at least one sensor (106, 108) for sensing the associated signals, and a sensor interface (110) coupled to the at least one sensor and configured to wirelessly couple sensor data received from the at least one sensor to an electronic device. The electronic device can be a mobile device such as a cellular radio telephone. The sensor interface includes sensing electronics which incorporates a sensor interface antenna configured for wireless coupling to an electronic device antenna when the electronic device and the sensor interface are in close proximity. The sensing electronics is configured to collate sensor data from the at least one sensor and to wirelessly communicate the sensor data to the electronic device by means of the wireless, coupling. The present invention has the advantage that the sensing electronics is provided in the garment rather than being co-located with the drive electronics. The sensor interface has no dedicated power source and derives its power from the electronic device through inductive coupling between the mobile device antenna and the sensor interface antenna. This removes the need for additional power source on the garment.
