Smart Building Integration (SBI) relies on using wireless sensors. These sensors must be powered. Cabling is too expensive and cumbersome, batteries have unacceptable maintenance and environmental issues and energy harvesting is not always possible. SBI will become feasible by employing rechargeable batteries that are remotely being recharged by means of radio waves while being functionally active within the sensor. Within the legal power restrictions and obeying the health exposure limit recommendations, the employment of a dedicated RF source has demonstrated the charging of a 3V battery indoors up to a distance of 18m.
This is an excellent and comprehensive review of the regulatory and physics environment that need to be properly understood during the planning and execution of Smart Building projects. I am looking forward to the next paper, where power from a boost converter is stored in a rechargeable device. I would also like to offer our help to extend testing to include our solid state rechargeable cells (4.1V) which should offer lifetimes in excess of 15 years in this environment.
very Interesting, do you have any paper that discusses solid state rechargable batteries, I beleive there are manufacturing complexities to make it commercially viable, but I could be wrong, this area of power is very interesting...
Hi Cezar,
I don't have such a paper immediately available, but contact my company and get in touch with our battery experts.
Best regards,

Armed with only a dynamic mic and a Schottky diode, I have for years been able to keep all the flashlights in our house at peak charge using only my ill-tempered, narcissistic wife's ranting voice.
Should I lease her out? Please advise.

Tex you have a new calling, if I didn't know better I'd think you were Robin Williams.
I can see it now, leave the toilet seat up, forget aniversaries and don't put the garbage out and we have the solution to our energy problems.
