The invention relates to the technical field of wearable detection, and particularly provides a wearable body sensing detection device and method. The device includes a wearable body sensing detectiondevice body, a micro processor arranged on the wearable body sensing detection device body, a wind pressure conducting panel, an energy conversion unit, a data calculation processing unit and a bodysensing auxiliary detection unit, wherein the wind pressure conducting panel, the energy conversion unit, the data calculation processing unit and the body sensing auxiliary detection unit are connected with the micro processor separately; wind pressure which is different in magnitude and is generated by the wind pressure conducting panel is converted into electric signals different in value through the energy conversion unit, and the data calculation processing unit creates a mathematic model and an algorithm to determine the relation between the electric signals and limb movement, so that body sensing based on wind pressure sensing detection is achieved.
