Careers: Physics/new materials


is there any materials which got the energy or got recharged from body electricity without being implanted into body. only staying under skin or organs

In my imagination, if scientist develop very very small nano chip which has the function of gps and antenna, and people inhale or eat without notice  and stay in human body....

So satellie and antenna traking the gps and shoot the elecromagnetic wave directly from the long distance, it could give person die or hurt. (becasue of the science development and nano tech development, I sometimes imagine this kinds of thinking)

of course, the tale is almost science fiction ,but I want to know whether it is right or wrong with the help of expert knowlege.

ANSWER: Hi terry,

I do not know of any "materials" of the kind you mention.  I do know that many researchers are in engineering are trying to develop energy harvesting "devices" that are worn on the body.  These are not yet as small as you imagine in your question.  If you do an internet search on energy harvesting and wearable, you will find many such articles.

I suppose that if a tracking device could be built small enough with energy harvesting it might be possible to do what you suggest but I don't think that a nano-scale such device yet exists.

In principle what you have described is possible although I doubt it has yet been achieved.  Nevertheless, it is unwise to say it can never be done given the fact that we now have cell phones that could only have been described as science fiction when I was growing up.

QUESTION: Thank you for your answer.
May I ask last query.
If we search smallest GPS receiver, certain company developed hair sized gps0.01mm.
And if we find self charging material, there is some material working with body heat.
And I also learned that it need capacity or charger because body energy is very weak to make gps system work with satellite
What I want to know is it possible to make such kinds of gps receiver with antenna and capcity with the shape of 1 or 2cm hair and weight of hair.
Until now, it is impossible, I understand all the informatio  from Internet is fiction until now.
Thank you

Well, I think that it might be possible but I would be foolish to say yes for sure and equally foolish to say no.  Since I am not directly in that field, i am unable to assess the current state of technology but I bet someone is working on such a thing.
