Abstract

The invention discloses a wearable miniature position sensor, and the sensor comprises a sealing layer, a printed circuit board layer and a support buffering layer, wherein the sealing layer, the printed circuit board layer and the support buffering layer are sequentially stacked from the top to the bottom. The printed circuit board layer is provided with a radiator circuit, and the radiator circuit comprises an access port for signal access, a grounding port for grounding, a capacitor connected between the access port and the grounding port, a coil in parallel connection with a capacitor, andan oscillator connected to the access port. The grounding port and the access port are connected to a coupling cable. Based on the circuit structure of the sensor, the near-field distribution of thesignals of a cable is achieved through the oscillator and the coil. The sensor can achieve the radiation at two bands which are far from each other, is simple in structure, and is small in size. The radiation distance can reach 1m, and the sensor can meet the test demands of the field of motion extraction.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a wearable miniature position sensor. Background technique [0002] The problem of short-range electromagnetic field radiation is different from that of antennas in the traditional sense. The energy of the electromagnetic field is concentrated in the Ferriel zone, and not most of it radiates to the far field to form a pattern. The applications of short-range electromagnetic fields are mostly concentrated in the fields of wireless charging and near-field communication NFC, both of which have a working distance of less than 10CM. The number of coil turns of the radiator for wireless charging is very dense, the power capacity is large, and the volume is also large, with an area of ​​about 10 cm. Due to the need for high-quality brass materials, the cost is also high; the near-field communication radiator is small, and the operating distance Also small, good only for work in snug situations. ...
