Nickel titanium memory alloy, also known as Nitinol, has made waves in various fields with its unique properties and applications. Here are some recent events related to this remarkable material.

In the field of medical devices

- Anti-torsion bone repair memory alloy nitinol patent: On October 18, 2024, Jiangsu Yahua Biotechnology Engineering Co., Ltd. obtained the patent of "anti-torsion bone repair memory alloy plate". This innovation is conducive to the reduction and repair of rib fractures. The unique design of the plate allows its components to be adjusted according to the actual situation of the fracture site, and combined with the heating action of the nickel-titanium shape memory alloy, it can effectively press the fracture site to assist the recovery process.
- Medical implantation project: In September 2024, the industrialization project of medical nickel-titanium shape memory alloy materials was officially launched in Enshi City. The total investment of the project is 110 million yuan, and the annual output value is expected to exceed 100 million yuan, which is an important step in the development of the medical device field in Enshi City. The project will build a high-purity nickel titanium raw material smelting line to produce three categories of high-precision medical device products, and the products will be exported to many countries and regions.

In the field of industrial technology

- SMA Nickel titanium memory alloy valve patent: Shanghai Taiyi Technology Co., Ltd. has made progress in the development of nickel-titanium memory alloy valves. In July 2024, the company applied for two patents related to SMA nickel-titanium memory alloy valves. One is "control system and method of electronic expansion valve based on SMA nickel-titanium memory alloy", which can improve the control accuracy of the valve port switch size. The other is "SMA Nickel-titanium memory alloy valve control system and method with resistance detection", which can expand the application range of SMA nickel-titanium memory alloy valve and accurately control the opening size of the valve.
- New discoveries in materials research: In the past, the development of shape memory alloys required a lot of experimental research and trial and error. However, with the advancement of technology, new research methods are constantly emerging. For example, using an AI material selection framework, researchers have discovered new shape memory alloys that show high efficiency in operation, providing new directions for the development of future materials.

In the realm of everyday life and entertainment

- Shape memory alloy products for daily use: nickel titanium memory alloys have also entered our daily life. For example, it is used to make glasses frames, and its excellent elasticity and shape memory function can guarantee the comfort and durability of glasses. In addition, some innovative products such as shape memory alloy toys and decorations have also appeared. For example, there are some toys whose parts are made of shape memory alloys that can change shape under different temperature conditions, bringing people a lot of fun and novelty.
- Dynamic decoration: In the field of art and decoration, shape memory alloys are used to create dynamic artworks. For example, some artists use shape memory alloys to make the skeletons of butterflies and flowers in potted plants, and through simple circuit control, the butterflies and petals can move dynamically, adding a unique charm to the decoration.

In short, nickel titanium memory alloys are constantly evolving and finding new applications in various fields. Its unique properties and advantages make it an important material for the development of modern science and technology, and its application prospect is very broad
