Objective: Under ubiquitous-healthcare circumstances, interest of one's health condition has been increased. People were required the measurement of biosignal by the wearable computing technology. The purpose of this paper is to measure the portable ECG (Electro- cardiogram) with the application of wearable computing technology. Therefore, the normal ECG measurement can be measured with a chest belt either in direct contract state or loose contact state. Methods: The belt type circuit for measuring ECG was developed. In order to remove noises in loosely contact condition, a shield circuit was assembled with the measuring electrodes. Both of High performance differential amplifiers and notch filters were incorporated into the main amplifier circuits. The ECG data was converted from analog to digital form by MCU (Micro Control Unit). The main memory was composed of a memory controller and a memory card. Results: The ECG measurement having bad electrode contact to body would be usually done in daily life, so we measured the biosignal by using the loose contact potable belt for accurate ECG data. The belt can be used to measure ECG by loose contact method. Conclusion: In this study, we could measure ECG without any spatial-temporal restriction due to the portable belt. This device is suitable for the ubiquitous-healthcare environment.
