OSAKA -- A new sensor developed by Sanyo Electric Co. could help people with sleep apnea, and may eventually regulate the environment in which one sleeps.
The sensor can measure the heart rate and number of breaths sleeping people take, without using special devices or body attachments.
The conventional approach measures the heart rate via several wires attached to the body, while breaths are counted using a restraining belt around the chest. Usually only medical institutions gather such data.
