Ration Calculating and Emulation of Enlarging Circuit of the Heart Electricity Signal of Bluetooth Technology
Wang Ha-li · Modern Electronics Technique · 2006
Bluetooth technology is the short distance wireless communication technology,it transmit from 10~100 m .In order to realize the heart electricity of the wireless short distance by using the technology of bluetooth,the article designs the amplifier circuit with two amplifiers,which can be used as amplifying the simulation of the electric monitoring system of portable heart,this text has carried on qualitative calculation and emulation . The circuit is high in sensitivity,the stability is good,which amplifies faint signal on human epidermis,then it is sent to A/D,finally it is launched out through the bluetooth chip.
