For monitoring respiration occurring through the respiratory tract or tracts of a patient, a sensor comprises two spaced-apart electrically conductive elements (2,3). Wires (8,9) extend from the elements to a measuring instrument. The transfer of an electrical charge between the elements is effected by means of charge carriers in an intermediate layer between the electrically conductive elements and responsive to moisture in respired air. The transfer provides an indication of respiration to a measuring instrument.
