Overcoming the Power Connudrum

I have written about the power consumption issue in earlier articles.  I now include a link to another article that discusses further positive developments in towards solving the power requirements problem inherent in remote patient care.  Here's the link to the article: Breakthroughs with Sensing in the Human Body By Dr Peter Harrop, Chairman, IDTechEx

The article discusses the following developments towards solving the power problem.  The two fundamental areas are:
  1.  Advancements in reducing the levels of power required for body sensor nets.  
  2. Methods for harvesting power: either from the wearer or from the environment.
Developments in power for portable and wearable devices are worth watching because the capabilities of remote patient care are limited primarily by power requirements.  Power requirements for pacemakers, ICDs and CRT(-D)s devices have by in large been met, that is, for those devices where the communications requirements are minimal.  However, as communications requirements increase, so will power consumption. And all indications are that data traffic requirements will increase, thus the need to both find more power and reduce power requirements will increase as well.

I shall continue to publish further developments in this area.
