Description

Technical Field

[0001] This invention relates to the technical field of flexible sensors, and in particular to a calibration and testing platform for a resistive flexible tactile sensor. Background Technology

[0002] With the continuous advancement of materials science and manufacturing technology, society and industry have put forward new requirements for the functionality, portability, and comfort of various electronic devices. Flexibility has become an important development direction for emerging electronic devices. Compared with traditional rigid electronic devices, bendability and deformability are important characteristics of flexible devices. They possess flexibility, elasticity, and the ability to withstand arbitrary deformation, showing broad application prospects in fields such as medical assistance, wearable health monitoring, and human-computer interaction.

[0003] Flexible tactile sensors can endow robotic hands with tactile sensations similar to human hands, serving as core components for intelligent robot perception and human-machine interaction. These sensors convert tactile signals into electrical signals, enabling rapid and accurate transmission of tactile information. Integrating multiple tactile sensor units onto a flexible substrate forms an N*M flexible tactile sensor array. This array, interconnected by wires, can be controlled by external circuitry to simultaneously measure changes in contact pressure at multiple points within a defined area, holding immense application potential in medicine, industry, and entertainment. Flexible tactile sensors can be broadly categorized into resistive, capacitive, and piezoelectric types based on their sensing mechanisms. The working principle of a resistive tactile sensor can be summarized as follows: external contact pressure causes a change in the sensor's resistance, resulting in a change in the output current or voltage, thus providing feedback on the magnitude of the contact pressure.

[0004] The core technology of resistive flexible tactile sensors is to construct a pressure-sensitive variable resistance system. Their calibration is generally performed on a dedicated platform. Currently, resistive flexible tactile sensors are usually placed in a fixed frame on the platform. Due to the lack of external protection, they are easily affected by external interference, resulting in unstable test results and poor reliability. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a calibration test platform for a resistive flexible tactile sensor that meets testing requirements while also providing easy-to-install and removable protection and improving reliability.

[0006] This invention discloses a calibration test platform for a resistive flexible tactile sensor, comprising a platform plate, legs, a resistive flexible tactile sensor placement frame, hinges, a cover frame, connecting frames, springs, guide rods, guide tubes, movable top plates, and fixed top plates. The four corners of the bottom of the platform plate are connected to the tops of a set of legs. The outer side of the top of the platform plate is connected to the bottom of the resistive flexible tactile sensor placement frame. The rear side of the top of the resistive flexible tactile sensor placement frame is connected to the lower rear end of the cover frame via hinges. A set of connecting frames is connected to the front and rear ends of the left and right sides of the top of the cover frame. The top of each connecting frame is connected to the top of a set of guide rods. The bottom of the guide rods is slidably connected to the top of the guide tubes.

Springs are sleeved on the guide rods and guide tubes, with both ends of the springs connected to the connecting frames and the movable top plates, respectively. A set of fixed top plates is connected to the lower left and right sides of the inside of the cover frame. A thin rubber layer is sandwiched between the two sets of movable top plates and the fixed top plates.
