Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sensors, and in particular relates to a perovskite flexible sensor device. Background Art
[0002] Perovskite materials have been widely used in the field of sensors in recent years due to their excellent photoelectric, magnetoelectric, acoustic and thermoelectric properties. Perovskite materials not only have high response speed and sensitivity, but also can convert external physical quantities (such as temperature, pressure, light, etc.) into electrical signal output, realizing the automatic detection and control functions of sensors.
[0003] Traditional flexible sensors usually have adhesive on one side to facilitate sticking them to the installation location. However, flexible sensors often need to be pasted repeatedly, especially in the field of medical testing. Repeated pasting can easily cause the adhesive on the surface to become non-sticky and easy to fall off. If they are fixed with tape, a lot of time is wasted each time finding and tearing the tape, making the pasting efficiency low. In order to solve the above problems, a perovskite flexible sensing device is now provided.
[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content
[0005] In order to solve the above problems, the purpose of the utility model is to provide a perovskite flexible sensing device, which controls the limit plate by pulling the driving plate to loosen the tape, and its output length can be controlled by pulling the tape. Then the flexible sensor is placed at the installation position and fixed by sticking the tape. When the viscosity of the tape outside the storage box decreases, it can be cut and new tape can be pulled out so that the sensing device can be repeatedly pasted. This method of fixing the flexible sensor does not require finding the tape, and there is no need to find the end of the tape when tearing off the tape, and the operation is simple.
[0006] To achieve the above-mentioned purpose, the utility model proposes a perovskite flexible sensing device, which includes a flexible sensor, and adhesive components for fixing the sensing device are fixed on both sides of the flexible sensor.
[0007] The adhesive assembly comprises a connecting piece fixed on the flexible sensor, a storage box is fixed above the connecting piece, the bottom of the storage box is hollowed out, and a tape roll is installed in the storage box.
[0008] Furthermore, a rubber pad is fixed to the bottom of the connecting piece.
[0009] Furthermore, the connecting piece and the rubber pad are provided with slits, and the adhesive tape on the adhesive tape roll passes through the slits.
[0010] Furthermore, the storage box is provided with slots above both ends, and a first arc-shaped rotating groove is provided in the slot. The pasting component also includes a U-shaped box cover, and a second arc-shaped rotating groove is provided below both ends of the box cover. A rotating shaft is fixed on the tape roll, and the rotating shaft is installed between the second rotating groove and the first rotating groove.
[0011] Furthermore, limiting strips are fixed on both sides of the box cover, and limiting grooves are provided on both side inner walls of the storage box.
[0012] Furthermore, an L-shaped connecting strip is fixed above the limiting strip near its side.
[0013] Furthermore, a limiting plate for squeezing the tape is slidably provided on the connecting piece.
[0014] Furthermore, a driving plate is vertically fixed on the limiting plate, and a spring is fixedly connected between the driving plate and the connecting plate.
[0015] The perovskite flexible sensing device proposed by the utility model can bring the following beneficial effects:
[0016] 1. The sensing device of the utility model loosens the tape by pulling the driving plate to control the limit plate, and its output length can be controlled by pulling the tape. Then the flexible sensor is placed at the position to be installed and fixed by sticking the tape. When the stickiness of the tape outside the storage box decreases, it can be cut off and a new tape can be pulled out so that the sensing device can be repeatedly pasted. This method of fixing the flexible sensor does not require finding the tape, and there is no need to find the end of the tape when tearing the tape, and the operation is simple;
[0017] 2. When the spring of the sensor device of the utility model is in the natural state, the limit plate pushes the tape against one side of the slit, which can prevent dust in the storage box on the one hand, and limit the tape on the other hand to prevent the tape from becoming longer when it is output;
[0018] 3. The sensing device of the utility model can lift up the box cover by inserting a tool such as a screwdriver between the L-shaped connecting strip and the box cover and pressing down the uninserted end of the tool, so as to facilitate replacement of the tape roll.
