The recent years have seen an increased interest in wearable devices as next-generation information terminal devices, healthcare monitoring devices, and medical devices that are thin, light, adaptable to various shapes, and do not break when dropped. In fact, numerous reports on wearable medical devices have been published. However, there are still many issues that need to be addressed to allow for the commercial production of such devices. We believe that printed electronics technologies could facilitate the effective production and global distribution of wearable medical devices. However, conventional silicon devices are also necessary when producing highly usable wearable medical devices. Accordingly, a hybrid of printed and conventional silicon technology should be developed.

JMC has been in the business of 3D printer output since 2000, and has successfully expanded its sales by focusing on marketing with a primary focus on attracting customers via the web. The equipment we mainly use is called a photofabrication system, which uses a special material that hardens through UV light. The processing accuracy of the device is ±0.15 mm; however, it can create complex shapes and curved surfaces in a short time, which is difficult to accomplish with other processing methods. We believe that this merit would be suitable for manufacturing organic shapes such as blood vessels and bones. In recent years, the usefulness of 3D printers in preoperative model surgery has gradually become widely known. One specific use for this is the preoperative simulation of jaw deformities. By using a model before surgery, it is possible to simulate whether a surgery could be performed with less burden on the body. Currently, the need is expanding, and competition is consequently increasing. The strength of our company lies in its ability to quickly create models that our customers want within a set cost. The use of preoperative simulators is also beneficial to patients, as it reduces surgical time and minimizes invasiveness through proper surgery. JMC will also use this model for the education of young doctors, which will lead to an early improvement in their skills. JMC will continue to enhance its more advanced models to contribute to the improvement of the safety of medical technology worldwide.

Since 2012, Inkjet printing technology has been primarily used to mark OD tablets. In particular, SCREEN started selling tablet printing machines in 2016. This paper discusses inkjet technology and its application to tablet printing. The manufacture of pharmaceutical products entails three processes: visual inspection, printing, and inspection of the printing. Our latest machine, OMNITO, is able to execute these three tasks automatically. In addition, we have developed a printing machine, BEVERSA, which can print serial numbers and expiration dates on aluminum sheets. This information enables pharmacists to easily check patients' medicines.

Thermal printers are widely utilized for medical reference hard copy systems because of their advantages, which include compactness, high-quality printing, high speed, high reliability, and low noise. Especially for diagnostic ultrasound systems and electronic endoscopes, monochrome direct thermal printers and dye sublimation thermal printers are the standard. The use of hard copies, which is mainly used for printer output, is expected to be lost due to recent digitalization. However, in actuality, the laws and regulations of each country and the print output application rooted in the medical workflow still prevail. This paper discusses the features of the thermal printer products and reports their usage status in the medical field.

Electrophoretic displays (EPDs) have been used in e-Readers for over a decade. These products have been widely adopted by consumers because of the superior user experience enabled by EPDs. Today, hospitals have also been evaluating products with this technology because of the improved experience it provides to both patients and hospital staff.

The ongoing standardization of the colors of printed material in the printing industry has led to the increased ease of accurate color reproduction among printing companies. However, in the medical field, the standardization of colors has been delayed. Consequently, the same subject is often observed in different colors owing to differences in cameras, scanners, displays, and lighting. This issue is one of the factors that delays the circulation of online medical care and AI diagnoses. In 2020, due to the COVID-19 epidemic, there has been an increasing need to convey accurate color information to remote areas. In light of these circumstances, a method for calibrating the color reproduction characteristics of medical equipment using a small color chart has been developed. This method is expected to improve the color accuracy of online medical systems in displaying complexion, and also to improve the accuracy of AI diagnosis with multiple imaging devices.
