The invention relates to a
plantar pressure measuring device and method. The device comprises a circuit layer and an insole, wherein the circuit layer is arranged in the insole; the circuit layer comprises a flexible
printed circuit board and a plurality of pressure sensors connected with the flexible
printed circuit board; the pressure sensors include a first sensor, a second sensor, a third sensor, and a fourth sensor. The insole comprises a
toe portion, a sole portion, and a
heel portion. The first sensor is arranged in the
heel portion, the second sensor is arranged on one side of the sole portion, the third sensor is arranged on the other side of the sole portion, and the fourth sensor is arranged in the
toe portion.
Pressure data when a person walks is calculated and obtained through the four sensors arranged in the
toe portion, the sole portion, and the
heel portion respectively, and then the
gait phase of the person is calculated according to the
pressure data. The device has the advantages that the whole device is light, wearing is convenient, and the flexible design better meets dressing requirements of the person, so that the person feels more comfortable when wearing the device; the number of the sensors is small, so that the cost of production is reduced.
