Abstract
This paper describes a development of networked non-invasive health monitoring system using an improved microphone for bio sensing. This system can estimate the person's sleep stages by analyzing the measured heartbeats and body movements. Microcomputers for each system calculate assessed sleep stages, and the central apparatus gathers all systems' data by TCP/IP network.
