摘要： The present disclosure provides a wireless sensor, a manufacturing method thereof and a wound flatness detection system. The wireless sensor includes a sensing element, two elastomer-made encapsulation layers and a breathable fiber-made encapsulation layer; wherein the sensing element is manufactured by the following steps: step 1: preparing a thin film using a carbon-based polymer solution; step 2: using a low-energy laser to induce molecular reconstruction of carbon-based groups on surfaces of the thin film to form a resistance-sensitive layer; step 3: using a high-energy laser to modify, carbonize and cut the resistance-sensitive layer to form a patterned sensing element. The present disclosure solves the problems that existing pressure or tension sensors are extremely susceptible to static interference from the external environment and the human body, and the mechanical mismatch between the sensing layer and the substrate, as well as the impermeability problem.
