The invention discloses a pressure sensing method and device used for intelligent shoes, and can be widely applied to the field of pressure sensors. The method includes the following steps that a processor obtains output voltage or output current of a sensor when shoe soles touch the ground instantaneously; the processor calculates the accelerated speed of the sensor in the direction perpendicularto the horizontal plane when the shoe soles touch the ground instantaneously according to the obtained output voltage or the output current; the processor obtains pressure exerted on a measured object of the sensor when the shoe soles touch the ground instantaneously according to the accelerated speed of the sensor in the direction perpendicular to the horizontal plane when the shoe soles touch the ground instantaneously. The pressure borne by the measured object is calculated through the accelerated speed of the measured object of the sensor in the direction perpendicular to the horizontal plane, and the involved sensor is only composed of a tubular track, a buffering assembly, a coil and a magnet. The manufacturing cost of the device is low, the sensor is simple in structure, damageableparts are not adopted, and therefore the reliability of the sensor can be improved.
Description
technical field [0001] The invention relates to the field of pressure sensors, in particular to a pressure sensing method and device for smart shoes. Background technique [0002] With the development of technology, embedded processors and micro-sensors have been significantly reduced in terms of volume and power consumption. Some miniature sensors introduced in recent years not only have multiple working modes and very low typical power consumption, but the working current of these microsensors in specific working modes can even be as low as several microamperes to hundreds of microamperes. Current pressure sensors generally use composite materials with piezoresistive effect, piezoelectric effect, or electrostatic capacity that changes with pressure to make their core components for gauge pressure sensing, and transmit pressure signals through peripheral circuits. [0003] The piezoelectric effect is the use of materials that generate current under pressure, such as piezoe...
