In collaboration with the University of Tokyo, the company developed a thin and stretchable skin display. With a unique mounting technology, 16 × 24 px micro light emitting diodes and stretchable wires were mounted on a rubber sheet. The size of the micro LED is 1 x 0.5 mm, the emission wavelength is 630 nanometers (nm) (red), and the drive voltage is 2 volts (V). Micro LEDs are embedded at equal intervals in a thin rubber sheet with a total thickness of about 1 mm (mm). Fitted to the skin, animation of the electrocardiographic waveform was displayed. This system integrating skin sensors and a skin display will improve health information on children and the elderly, and is expected to be applied to, e. g., home health care.
