Teijin promotes the development of wearable devices integrating highly functional materials, sensing techniques and know-how in home healthcare to provide new solutions.
New coaching wear that helps to improve sports skills is among the wearable solutions offered by the company. The coaching wear visualises the difference between the actual motion of wearers and their ideal motions by capturing them with the accurate sensing technology.
It is a combination of motion sensing technology and Teijin’s ultra-fine polyester nanofibre Nanofront, which has highly slip-resistant property, so the sensing wear provides good comfort without restricting athletes’ movements and strong compression. “The conventional way of obtaining image data requires special devices and places, such as camera and photo-studio, but new coaching wear enables to detect movement by just wearing the sensing wear,” the company explains.
Vital sensing wear
This clothing facilitates sustainable and highly accurate sensing of the heart’s electrical activity, heart rate and activity levels, minimising the noise generated by the contact of the body with sportswear during exercise.
It combines the ultrafine fibre Nanofront with vital-sign sensing technology. It can be used in various scenarios including sports team management and the prediction of heatstroke risk. “Our original wireless communication technology made it possible to collect the personal data simultaneously up to 1,000,” the manufacturer adds.
Piezoelectronic braided cords
A sensor in the shapes of Japanese traditional braided cords, known as kumihimo, detects user’s motions. For example, soccer shoes featuring this sensor detect contact area of the ball from kicking impact. The hitting power of tennis ball on each string is also detected by sensor installed in the racket’s gat.
“This soft and flexible piezoelectric braded cords enable the sensors to be fashioned in a wide variety of thicknesses, lengths and shapes. Other useful features are low noise and high sensitivity,” the company reports.
The wearable electrode textile incorporated the traditional Japanese Nishijin-brocade weaving technique enables rapid, accurate 12-lead electrocardiogram (ECG) measurements. “To increase surviving rates, quick and accurate measurement is desirable prior to emergency transport, especially for cardiac disease which is highly required for rapid treatment,” the company explains.
“The normal procedure is to fix 10 electrodes to the patient, but it is difficult to perform correctly in the field under emergency conditions. This wearable ECG-textile will solve the issue by following the guidelines on the strip e-textile to the patient’s chest (size S, M, L and LL) to wrap around without adjustment for electrode.”
2breathe supports good sleep
This smart device and mobile app is designed to lead you to sleep, relieve pre-sleep tension and midnight wake up issues. The vertical movement of abdomen is detected by this small device, which sends the data to smartphone via Bluetooth, and the app converts it to sound.
It is said to help reduce the neural sympathetic activity by relaxing your mind and body when your breath is synchronised to the sounds.
Smart firefighters’s uniform
The smart firefighter’s uniform predicts heatstroke risk by estimating deep body temperature. The device installed in this uniform monitors the temperature and precise position of firefighters and transmits the resulting data in real time to management systems at the scenes of fires and to firefighting headquarters, where it can be analysed to accurately estimate deep body temperature.
The uniform is made with heat-resistant, flame-retardant Teijinconex meta-aramid fibre and high-tenacity Technora para-aramid fibre. The card case-sized sensing device is developed by Teijin’s IT business, using impact-resistant polycarbonate resin Panlite.
