What is the basic role of electronics in biomedical monitoring?

Bio medical is Sub branch of Electronics , so we cant determine its role in Bio medical .
As it named on the basis of it use or applications.
As we can see lots development in electronics everyday so that is helping to all other branches for development in the technical specifications.

Real-time biomedical data acquisition is changing through advances in microelectronics fabrication, bio-MEMS and power micro-generators.
Such data acquisition and processing systems are becoming increasingly miniaturised, flexible and pervasive, while data is being collected from inside the human body as well as around it..
Once the signals to be monitored have been identified, it is important to use appropriate sensors to collect the same.
Cheaper commercial ones and custom built sensors are being focused on

99.99 % medical equipments in today life are electronically operated and are totally or partially automatic in function using micro controller and microprocessor based technology and high tech computing work stations.
infect electronics is the backbone of biomedical monitoring systems,as these are life saving systems like ECG, Ultrasound, patient monitors, cardiac monitors, anesthesia ventilators and many more.

Really , the majority of biomedical systems composed from electronic that used to data acquisition , amplification , controlling , filtering and finally converting the signal from analogue to digital for further processing in computers.
