Viruses Engineered to Construct Batteries

An anonymous reader writes "Researchers at MIT have modified the M13 virus to create very small batteries. With the viruses building wires 6 nanometers in diameter, the research team hopes to 'build batteries that range from the size of a grain of rice up to the size of existing hearing-aid batteries.'"

Manometers?

Maybe pressure measuring devices can be next on the list of virus-built machines.
