Fuente: Wipo "Sensorization" A sensor unit includes a first sensor portion that detects deformation of an object to be measured and has a film shape, a second sensor portion that detects deformation of the object to be measured and has a film shape, and a sheet to be attached to the object to be measured. A main surface of the first sensor portion and a main surface of the second sensor portion are attached to the sheet. In a state that the sheet is expanded in a plane, the main surface of the first sensor portion has a portion not overlapping the main surface of the second sensor portion, and the main surface of the second sensor portion has a portion not overlapping the main surface of the first sensor portion, in a view in a direction normal to the main surface of the sheet.
