Embodiment Construction
[0014] to attach figure 1 The present invention will be further described for the specific embodiment:
[0015] A capacitive magnetic field strength sensor based on magnetic liquid droplets, the sensor includes: a positive connection port 1, a negative connection port 2, a capacitor positive plate 3, a capacitor negative plate 4, a magnetic liquid droplet 5, and sealed air 6 , Seal the cavity 7.
[0016] The positive connection port 1 is connected to the positive electrode plate 3 of the capacitor, and the negative connection port 2 is connected to the negative electrode plate 4 of the capacitor. The positive electrode plate 3 of the capacitor and the negative electrode plate 4 of the capacitor are respectively located on both sides of the sealed cavity 6. Located at the bottom of the sealed cavity 7 , the sealed air 6 is located at the upper part of the sealed cavity 7 .
[0017] The overall size of the sensor is on the order of millimeters. When there is no external magnet...
