EQUIPMENT FOR MEASURING BIOELECTRIC IMPEDANCE WHOSE CIRCUIT IS INTEGRATED INTO ONE CHIP

摘要

PROBLEM TO BE SOLVED: To provide a low-cost and highly accurate equipment for measuring bioelectric impedance that needs fewer parts for circuits and is made in fewer manufacturing processes and to provide a device for measuring body fat using it. SOLUTION: The equipment is made with a microcomputer which contains one chip where most of the necessary functions to measure bioelectric impedance are integrated. The equipment for measuring bioelectric impedance also contains a one-chip microcomputer for most of the necessary functions for measurements in multiple frequencies or with multiple electrodes. The equipment for measuring bioelectric impedance contains a one-chip microcomputer for most of the necessary functions for measuring other parameters by connecting to outside sensors besides measuring biological electric impedance.
