The invention relates to a multidimensional joint gesture detection sensor, and aims at solving the problems of large detection error of an inertial detection method and a video detection method which are usually adopted in conventional measuring means for body gestures. Two ends of a flexible corrugated pipe are connected with corresponding fixed disks; detection modules are connected with corresponding fixed disks; two first displacement sensors are disposed in a hollow cavity; four shell through holes are aligned to four fixed disk through holes; four steel wire sliding tracks on the same circumference are provided with a steel wire respectively; the upper end of a second steel wire is connected with one of the displacement sensors; the upper end of a fourth steel wire is connected to the residual displacement sensor; the upper end of an upper wiring harness passes through an upper fixing block; the lower end of a first steel wire is connected with one of the displacement sensors; the lower end of a third steel wire is connected with residual displacement sensor; and the lower end of a lower wiring harness passes through a lower fixing block; The multidimensional joint gesture detection sensor is used for measuring biological gestures.
