Abstract: A patch is provided. The patch comprises: a base layer; and an adhesive layer formed on a surface of the base layer, the adhesive layer has a wave pattern such that 95% or less of the area of the surface of the base layer is covered by the adhesive of the adhesive layer, wherein, the patch has an elongation of at least 120% in both machine direction and cross-machine direction.

Abstract: An ear physiological wearable device, including a main body and a supporting body, is provided. The main body includes an acoustic driving portion, a temperature sensing portion and an optical scanning portion. The acoustic driving portion is adjacent to the temperature sensing portion, and the optical scanning portion is disposed below the acoustic driving portion and the temperature sensing portion. The supporting body is connected to the main body. The acoustic driving portion includes an acoustic outlet, and the temperature sensing portion includes a nozzle. Two ear physiological wearable devices, one of them including an acoustic driving portion with an acoustic end against the user's skull, another including a main body including a temperature sensing portion and an optical scanning portion, are provided. In this way, the audio signal can be transmitted and/or the users' physiological status can be sensed.
