Abstract
A physiological sensor device for attachment to a mammalian subject comprising an output transmitter, at least two physiological sensors each for sensing one of the subject'"'"'s physiological parameters, and a controller operably in communication with the physiological sensors which controller communicates a signal comprising data representative of both the sensed physiological parameters to the output transmitter which operably transmits the signal to a remote location, wherein the controller comprises a multiplexer which operably switches the data from both the physiological sensors into a serial output signal. In a preferred embodiment, respiration is detected by a bend sensor including an elongate member and an electrical component mounted thereon which electrical component has an electrical property which varies in dependence on the extent of bending of the elongate member. Other parameters such as temperature and full waveform ECG may also be measured.
