In biomaterials research, wire tensile testing is an important experimental method for evaluating the mechanical properties of materials, such as elastic modulus, yield strength, and fracture toughness. Such tests demand extremely high precision, especially when dealing with micro- or nanoscale biomaterial wires, where traditional measurement methods often fail to meet the testing requirements.
Traditional methods usually rely on contact strain gauges or sensors for measurement, but these methods have obvious limitations in microscale measurement, such as difficulty in providing sufficient accuracy; contact measurement may also introduce additional errors or even damage the specimen. To overcome these problems, the Haytham visual microscopic strain measurement system, with its advanced digital image correlation (DIC) technology, provides an accurate and efficient solution for tensile testing of biomaterial wires.
1. Non-contact measurement: Traditional contact measurement methods may damage the specimen or interfere with the experimental results, whereas the Haytham system achieves fully non-contact measurement through digital image correlation analysis, avoiding these problems. This is particularly critical for handling sensitive biomaterials, as it ensures the true mechanical behavior of the material in its natural state.

2. High-precision microscopic strain measurement: The Haytham system adopts advanced DIC technology, capturing deformation images of the material surface through a high-resolution microscope and performing precise strain calculations. Compared with traditional methods, the system can measure the minute strain of extremely fine wires at the microscale, ensuring the high accuracy and high credibility of the experimental data.


3. Real-time strain analysis: The system features real-time strain analysis, outputting stress-strain curves in real time during tensile testing while simultaneously recording the deformation characteristics of the material during tension. Unlike traditional methods that require post-processing of data, this function provides researchers with immediate experimental feedback, making it easy to adjust experimental parameters or perform in-depth analysis in time
