Charles Razzell  
1/17/2013   10 comments
There's a lot that could be gained by incorporating both analog and digital techniques, but keeping it "pure" has its advantages, too. Charles Razzell gives the lay of the land.

The utilization of electronics in medical applications could effectively enhance the quality of life of patients and prevent many cardiovascular distresses: this is confirmed by the result of an observational study, about the CPAP device
This blog series deals with the potential of the utilization of smart electronic ICs in medical care applications; these ICs are produced by companies in the field of semiconductors such as STMicroelectronics which has a broad portfolio of ICs for medical applications
There is rising interest in alternative energy schemes and electric vehicles (EVs) which means there is a growing need in making it possible for power to flow efficiently in both directions.
The industries sector is progressively increasing utilization of IoT technology to make the industrial processes automated in a very intelligent way.
Medical care applications with electronic devices are becoming progressively more important and massively adopted.
