Development of a portably embedded pulse signal acquisition circuit

Pulse diagnosis is an important component of the diagnosis methods in traditional Chinese medicine.In order to develop a portably embedded pulse signal acquisition circuit,this paper took the following methods:① Power:Used USB bus power supply.Without an extra power supply to reduce the size of the circuit and increase the field of application.② Component:Used low power dissipation and small electronic component.③ Design:Used elaborated design on software,hardware,function,size,and power dissipation,good components,excellent circuit design,and fine communication guaranteed accurately real-time signal acquisition.In conclusion,this circuit design is practical and can work well.
