PROBLEM TO BE SOLVED: To deal with the trouble with a device for measuring impedance of bioelectricity that an excessive current flows into a human body in case of a failure or a damage in an element, by using a simple composition of a circuit without lowering the accuracy of measuring. SOLUTION: The device is composed of a circuit for measuring impedance of bioelectricity. A capacitor is inserted between the circuit and an electrode put on the human body or a resistance is inserted in parallel with the capacitor. The circuit has a means for generating an alternating current for measurement that flows into the body, a means for measuring a voltage value, a means for calculating the impedance of bioelectricity and a CPU(central processing unit) for controlling and calculating. |
