A flexible sensor comprises a first elastic circuit module, a second elastic circuit module and a hot melt adhesive film. The first elastic circuit module includes a first elastic film and a first conductive pattern. The first elastic film is elastically deformable by stretching and has a printed printed carrier layer and a thermal bonding layer. The first conductive pattern is formed by printing in printing. Carrier surface. The second elastic circuit module includes a second elastic film and a second conductive pattern. The second elastic film is elastically deformed by stretching, and the second conductive pattern is formed on the second elastic film by printing and has a shape and a first conductive pattern. Cooperate. The hot melt adhesive film is joined to the first elastic circuit module and the second elastic circuit module via a thermocompression bonding method and can be elastically deformed by stretching together, and the positions of the first conductive pattern and the second conductive pattern correspond to each other and the heat The melt film together constitutes a capacitor structure.一種柔性感測器，包含第一彈性電路模組、第二彈性電路模組及熱熔膠膜。第一彈性電路模組包括第一彈性膜及第一導電圖案，第一彈性膜可受拉伸彈性變形且具有相層疊的印刷載層及熱接合層，第一導電圖案以印刷方式形成於印刷載層表面。第二彈性電路模組包括第二彈性膜及第二導電圖案，第二彈性膜可受拉伸彈性變形，第二導電圖案以印刷方式形成於第二彈性膜且形狀大小與第一導電圖案相配合。熱熔膠膜經由熱壓合方式與第一彈性電路模組和第二彈性電路模組接合並能一起受拉伸彈性變形，且第一導電圖案和第二導電圖案的位置相對應並與熱熔膠膜共同構成電容結構。
