Team led by associate director, Shuguang Zhang managed to use the energy generated by trees to power a network of wireless sensors (-Tree Power-), Professor Zhong Lin, Wang research group managed to generate power from Fabric (-Fabric Generate Power Caught Global Interests...-), and now MIT engineers led by professors Yet-Ming Chiang have developed a way to create and install tiny microbatteries, about half the size of a human cell and built with viruses which could one day power a range of miniature devices, from labs-on-a-chip to implantable medical sensors -- by stamping them onto a variety of surfaces.

In the Proceedings of the National Academy of Sciences (PNAS) the week of Aug. 18, the team describes assembling and successfully testing two of the three key components of a battery. A complete battery is on its way.

"To our knowledge, this is the first instance in which microcontact printing has been used to fabricate and position microbattery electrodes and the first use of virus-based assembly in such a process," wrote MIT professors Paula T. Hammond, Angela M. Belcher, Yet-Ming Chiang and colleagues. Read more in MIT Tech Talk.
