Oct. 11, 2002 — Nippon Telegraph and Telephone Corp.’s Microsystem Integration Laboratories said it has developed a tiny blood-flow sensor that takes readings from the fingertip, according to Asia Pulse.
The device, which has a built-in laser diode and photodetector, can measure blood flow in the capillaries below the skin just by placing a fingertip on the sensor. The sensor is connected to a small terminal, which enables changes in blood flow to be depicted graphically, according to the report.
The lab also is developing a wireless technology for transmitting data from the terminal to the hospital. A commercial product is expected within three years, the report said.
