Shoe built-in piezoresistive body weight sensor

Abstract

A shoe built-in piezoresistive body weight sensor belongs to the technical field of wearable body weight testing and relates to a shoe built-in piezoresistive body weight sensor. The sensor breaks the spatial range restriction of monitoring diagnosis by medical institutions, facilitates daily body weight monitoring, and can provide theoretical basis for human foot health care, movement posture correction and scientific shoe making. The sensor comprises an output end, a first polyester film and a second polyester film. The first polyester film and the second polyester film are arranged from top to bottom one by one. A first silver electrode layer, a pressure-sensitive ink layer and a second silver electrode layer are arranged between the first polyester film and the second polyester film. The first silver electrode layer is arranged on the upper surface of the pressure-sensitive ink layer, and the second silver electrode layer is arranged on the lower surface of the pressure-sensitive ink layer. The first polyester film, the second polyester film, the pressure-sensitive ink layer, the first silver electrode layer and the second silver electrode layer are all in the shape of a shoe pad. The first silver electrode layer and the second silver electrode layer both extend to the output end.

Description

technical field [0001] The invention belongs to the technical field of wearable body weight testing, and relates to a shoe built-in piezoresistive body weight sensor. Background technique [0002] As we all know, wearable devices are regarded by the industry as a new industry growth point after smartphones and tablet computers. The more representative smart wearable products on the market now include smart bracelets, smart watches and smart glasses. These wearable devices are used on the upper body of the human body. In order to improve the scope of use of smart wearable devices, smart shoes are an effective supplement. [0003] The survey found that when a person stands statically, the gravity on the sole of the foot is F=G. When walking, the gravity on the soles of the feet is equivalent to 110-125% of the body weight, that is, F=1.1-1.25G when walking; the maximum kicking force of a person is about 4G during middle-distance running, 5G for sprinting, 6G for long jump, a...

AI Technical Summary

Problems solved by technology

Traditional scales and electronic scales cannot measure these dynamic "weights". At the same time, the current plantar pressure test products focus on measuring the distribution of plantar pressure, but they cannot meet the needs of measuring dynamic "weight". Human foot medical care, sports posture correction and scientific shoemaking, etc., all need a product that can measure dynamic "weight"
