Abstract
Using microprocessor techniques, a portable digital memory device has been designed for the ambulatory monitoring of heart rate and physical activity. The device consists of a microprocessor, an ECG amplifier t o record the heart rate and an accelerometer to detect the physical ac tivity. This accelerometer is piezoresistive and is suitable for ambul atory physical activity recording, because this sensor requires low el ectrical power, has high durability and wide frequency response (DC is similar to 1.2 kHz). Changes in heart rates and physical activity in daily life have been successfully recorded.
