Peripheral heart rate detection based on a monolithic impedance meter

Abstract

The objective of this project is to identify the peripheral heart rate in the arm or hand, using dry electrodes and an impedance converter monolithic, by bioimpedance measures. To perform the project, first has been characterized impedance converter. (we used the AD5933 from Analog Devices). Different possibilities have been raised for signal conditioning, seeing the viability of each one. Once you have found which responded to the objectives of the project is described in depth. For interaction with the user has designed a Visual Basic program that performs the data capture for post processing. Finally, we show the results of the measures taken in the arm and hand.
