The present invention relates to a physiological signal measuring device, and more particularly to a wear sensing device for dynamic sensing signal measurement using an acceleration gauge.

Dynamic sensing of human posture is an important indicator for assessing the gait parameters, balance ability and risk of falls in the elderly. It is more meaningful for the early symptom monitoring or prognosis evaluation of patients with stroke and Parkinson's disease. However, the current device for measuring changes in the posture of the human body mainly uses a method in which a plurality of accelerometer sensing modules fixed to the human body are connected to the wires to collect data and follow-up monitoring.

Since the accelerometer sensing modules need to be fixed to the body one by one and connected to a plurality of wires one by one, it is quite inconvenient to wear. Even if the accelerometer sensing module and the wire are fixedly mounted on a wearing device, the detachment and reinstallation of the accelerometer sensing module is very troublesome, so the user usually does not clean the wearing device. The detachment of the accelerometer sensing modules thus detracts from the problem of cleaning and sanitizing the wearer. Furthermore, the accelerometer sensing module is liable to cause relative displacement on the wearable device and the portion to be measured, and the measurement error is caused, and the wire and the accelerometer sensing module are often Pulling and there is a problem that the sensing signal is attenuated or cannot be completely received.

And a accommodating member fixed to the fabric corresponding to the number of the fabric wires, and defining an accommodating space, the accelerating scale group is detachably received in the accommodating member; The detaching member is detached, and the fabric together with the accommodating member can be cleaned by a general washing method.

The accelerated scale group further includes an encapsulation layer encapsulating the circuit substrate and the accelerometer wafer, the protective shell encapsulating the circuit substrate and the accelerometer wafer covered by the encapsulation layer, and the external shape of the encapsulation layer The inner space shapes of the protective shells cooperate with each other to provide a foolproof function.

Wherein the protective shell of the accelerated scale group is fixed to the fabric, The accelerated scale group further includes an encapsulation layer encapsulating the circuit substrate and the accelerometer wafer, and the circuit substrate and the accelerometer wafer covered by the encapsulation layer are detachably embedded in the protective shell, and the encapsulation layer is externally The shape and the internal space shape of the protective case cooperate with each other to provide a foolproof function.
