Abstract

The invention discloses a flexible single-point force sheet sensor which can detect the force of a certain point that contacts to an object and a preparation method. The sensor comprises an upper base plate and a lower base plate in the same shape and size, a pressure sensitive body, two electrode connecting sheets which are arranged at both end surfaces of the pressure sensitive body; the position between the upper base plate and the lower base plate is sealed by an adhesive coating; a projection is arranged at one side close to the upper base plate in the length direction; a hollow is is arranged at the lower base plate corresponding to the projection; a sealed pressure sensitive body chamber is formed between the projection and the hollow, wherein the pressure sensitive body and the electrode connecting sheets are positioned at the sealed pressure sensitive body chamber; two mutual parallel printing electrodes are arranged at the position between the lower base plate apart from the side of hollow and the length direction of the hollow; each printing electrode is connected with one electrode connecting sheet at one side of the hollow of the lower base plate; one end of the lower base plate apart from the side of hollow is connected with an electrode lead sheet which is exposed at the lower base plate; an electrode protecting film is positioned at an upper surface which is connected the electrode connecting sheet with the electrode lead sheet.

Description

technical field [0001] The present invention relates to a sensor and its manufacturing method, in particular to a flexible single-point force piece sensor and its manufacturing method for detecting the pressure or concentrated force between one-point contact objects in a narrow contact area. Background technique [0002] Pressure sensors and detection technology play an important role in aerospace, military industry, automobile, shipbuilding, industrial automation, medical research, biomedicine and other fields. However, in the above application fields, in many cases, it is necessary to detect the pressure or concentrated force between objects in contact with a point in a narrow space, such as the study of the interaction process of friction between objects in motion, such as the detection of space cams The interaction force with the roller follower in the state of point contact, the interaction force when detecting a certain pair of teeth meshing, etc. Due to the limitatio...
