UK research institutes collaborate to develop 3D printed RFID wearable electronic devices

Recently, thanks to the collaboration of two research institutes in the UK, the Process Innovation Center (CPI) and the University of Kent, we have taken another step forward in the realization of 3D printed electronics. Researchers at both organizations used a state-of-the-art 3D printing technology to print a bracelet that incorporates advanced antenna and RFID technology. In this project, Kent University is responsible for the design and 3D printing of the bracelet, and the antenna components are also manufactured using 3D printing technology, but in the CPI's National Printable Electronics Center.

The University of Kent is considered to be one of the major centers of global antenna and RFID technology development, while CPI is at the forefront of electronic 3D printing technology. The goal of the partnership is to create a wearable product that can be quickly 3D printed and does not require assembly. The product also has tracking or identification capabilities. The design can be used for 3D printing of customized products with special applications, such as bracelets for patients, which integrates device recognition expressions, can be used in a hospital environment, and can be connected to a local WiFi hotspot. The project leader at Kent University is Dr. Benito Sanz, an electronic systems instructor with more than 10 years of experience in developing antenna and RF technology.

“The demonstration of such an available electronic bracelet prototype represents a significant achievement in the commercialization of wearable electronics, especially the integration of 3D printed bracelets with antenna printing technology. Printable electronics bring wireless sensor applications A lot of opportunities. Looking ahead, the next step of development will focus on process optimization, and the scope of application of this technology will also be extended from development prototypes to product trials,” Sanz said.

CPI is a technology innovation center that helps high-tech start-ups develop, validate, prototype and improve the manufacturing processes of next-generation electronic products. The center has state-of-the-art R&D technology and combines science and engineering to help their customers understand the performance of their products or technologies under high-volume manufacturing conditions and may accelerate their production schedules and reduce costs.

The antenna in the bracelet is printed using a 3D printing technique called aerosol jet, which uses a silver ink that forms a geometry that is difficult to replicate in any other manufacturing method. These inks can be printed on almost any surface and can be arbitrarily configured. Not only does this reduce the cost of wearable electronics, but it also increases its functionality, which is not available with rigid boards produced using traditional manufacturing methods, and they can quickly enter mass production stages.

The ability of such 3D printed electronic components, such as circuits or antennas, will open up a whole new world of design and development of personal electronic devices and wearable technologies. It will enable people to create stronger, lighter, smaller, more comfortable and smarter wearables. These devices will not only be connected to the Internet, but also smarter and more interactive, while providing a friendly user interface. For example, in the future, consumer electronics like a full-featured smart watch will cost less than five or six hundred dollars, and future products will consume less power. They can also be customized according to user requirements. .
