Abstract: An induction unit, a touch detecting assembly, and a touch sensitive device are provided. The touch sensitive device comprises: a substrate (100); a plurality of induction units (200) not intersecting with each other, and a detecting module (300) connected with the first electrodes (210) and the second electrodes (220) respectively. The induction unit (200) comprises a first electrode (210), a second electrode (220), a plurality of first structures (230) and a plurality of second structures (240). The plurality of first structures (230) are connected end to end via the plurality of second structures (240). The detecting module (300) is configured to apply a level signal to the first electrodes (210) and/or the second electrodes (220) to charge a self capacitor, to calculate a ratio between a first resistor and a second resistor, and to determine a touch position in a first direction and a touch position in a second direction.
