Viruses Are Building Micro Batteries

MIT engineers have developed a way to create micro batteries which could power a range of miniature devices, from labs-on-a-chip to implantable medical sensors. These next-generation batteries may be half the size of a human cell and are built with viruses.

Viruses Are Building Batteries!

Have you ever 'seen' a battery as small as half the size of human cell, and built with viruses?

8755collage If you think AAAs batteries are small, then consider this: Next-generation batteries may be half the size of a human cell and built with viruses. Now that’s small. MIT says this is the way of the future when it comes to powering tomorrow’s miniature electronic devices.

MIT engineers work toward cell-sized batteries

Forget 9-volts, AAs, AAAs, or D batteries: The energy for tomorrow's miniature electronic devices could come from tiny microbatteries about half the size of a human cell and built with viruses. MIT engineers have developed a way to at once create and install such microbatteries by stamping them onto a variety of surfaces. In the image above, tweezers hold the device used to test MIT's new components for the microbatteries. The batteries themselves are too small to be seen.
