Bluetooth technology is a low-cost proximity connection that was created in 1998 by Telefonaktiebolaget LM Ericsson. Bluetooth technology can be in and so on between many devices for wireless information exchange, can make some of the current portable mobile devices and computer equipment can be connected to the Internet without the need for cables, and can be wireless access to the Internet. In our lives many devices are used Bluetooth technology, such as smart phones, Bluetooth headset audio, etc., which greatly facilitates our lives. Bluetooth technology is also often used in the field of medicine, the diagnosis will be delivered to the doctor, ward monitoring. Bluetooth technology also enhances people's productivity, technicians can use Bluetooth to wirelessly monitor CNC machine tools. However, over-reliance on Bluetooth can also make people addicted to it, affecting work efficiency.

Smartphone is a device that has an independent operating system and independent operating space and can be installed by the user with software, games, navigation and other devices provided by third-party service providers. It is a general term for the type of mobile phone that can be used to achieve wireless network access through mobile communication networks. The world's first recognised smartphone, the IBM Simon, was born in 1993 and was manufactured by IBM in collaboration with BellSouth. In the 21st century, people's lives are almost inseparable from smartphones, and many functions such as mobile phone payment, online shopping and chatting have greatly facilitated people's lives. People can make payments through the e-wallet on their mobile phones, and compared to traditional offline shopping, online shopping is much more selective. And more cost-effective, more and more young people choose to do e-commerce, but also provides them with good employment prospects. With a smartphone, you can contact your friends through chatting apps without using your phone bill to make calls. However, over-reliance on smartphones often also causes great harm to people. Many children are addicted to online games to indulge in them, thus delaying their studies, and many unscrupulous people also commit fraud through smartphones.

Artificial Intelligence is an important driving force of the new round of scientific and technological revolution and industrial change, which was first proposed by the DARTMOUTH Society in 1956. Artificial Intelligence is a new technical science that researches and develops theories, methods, technologies and application systems used to simulate, extend and expand human intelligence. Nowadays, artificial intelligence is also gradually inseparable from our lives, many places can see its figure, such as smart door locks, fingerprint recognition, face recognition, ChatGPT, etc., artificial intelligence greatly facilitates our lives, with smart door locks, people will not be afraid to go out without a key to return to their homes. People can unlock their smartphones through face recognition technology. Artificial intelligence can also often be used in production, it can replace manual labour to do some more dangerous work, it is also much more efficient than human beings.

Nanotechnology is the science and technology of making matter from individual atoms and molecules, the study of the properties and applications of materials with structural dimensions in the range of 1 to 100 nanometres, it was invented in 1981, there are many types of nanotechnology, it is broadly categorised as molecular nanotechnology, bio-nanotechnology. The current research and applications of nanotechnology are mainly in materials and preparation, microelectronics and computer technology, medicine and health, space and aviation, environment and energy, biotechnology and agricultural products. Devices made from nanomaterials are lighter in weight, stiffer, longer in life, less expensive to maintain, and easier to design.

5.3D Printing

3D Printing, also known as Additive Manufacturing Technologies, AM, is a technology for manufacturing solid parts based on three-dimensional CAD data through a layer-by-layer material accumulation method. It was invented by Chuck Hull in 1986, and the historical development of 3D printing technology is a process of continuous progress and expansion. From the early days of rapid prototyping to today's wide range of applications, 3D printing technology has been used in design and manufacturing fields such as jewellery design, industrial design, architectural design, engineering design and construction, automotive design and manufacturing, as well as in medical fields such as aerospace and dentistry. This also greatly facilitates our life, you can make what you want through 3D printers.
