Let your body charge your Smart Watch

When scientists realized that human body functions among all other things generate electromagnetism and heat by nature to correct many dysfunctions within itself. The inventions got even better using those very magnetic, kinetic and heat remittance processes from within our body.
Like once Seiko experimented with Kinetic watches years ago here’s a trending entrant. A SmartWatch powered by human body heat cycles. More affordable than the Seiko of the yesteryear this SmartWatch uses Thermoelectric technology to convert Heat from within human body to power the Watch. Forget charging, batteries or the run of the automatic traditions.
The technology was primarily a process of NASA used for its Voyager and Curiosity missions. The sole objective for Thermoelectric powering of the Watch was to conserve on the externally provided batteries and use whatever could be from the human body processes. This is not a new gadget coming out of NASA labs and hitting a consumer base. NASA has experimented with magnetic locks that are almost literally unbreakable in the past and had them marketed to test the reliability and gather feedback. Later on the locks were only available at select stores. Now they are not available at all.
If the future holds unlocking the Sensory Technology for the masses such watches would be a blessing as they are ‘area dependent’ and gather as much needed Thermoelectricity through specialized sensors from its strap’s underside touching the skin, in turn converting it into a heat signature that powers it. It is extremely useful technology for hospitals and health care. Not to mention it is Smart and it has no battery nor needs charging.
