Abstract: Disclosed are a bladder monitoring method and apparatus based on a multi-channel strain bladder sensor, and a multi-channel strain bladder sensor verification method and apparatus. The multi-channel strain bladder sensor verification method according to an embodiment of the present disclosure may comprise the steps of: controlling expansion and contraction of a measurement object acting as a bladder; acquiring a sensing value from each channel of a bladder sensor attached to the measurement object, according to the control of expansion and contraction of the measurement object; tracking the volume change and expansion direction of the measurement object by analyzing data regarding the change in the sensing value from each channel of the bladder sensor; and verifying the bladder sensor on the basis of whether the volume change and expansion direction of the measurement object are included within the standard range corresponding to the control of expansion and contraction of the measurement object.
