Query: Electrokinetic Energy Harvesting using Paper and Pencil   We exploit the combinatorial advantage of electrokinetics and tortutosity of
cellulose-based paper network on a laboratory grade filter paper for the
development of a simple, inexpensive, yet extremely robust (shows constant
performance till 12 days) paper-and-pencil-based device for energy harvesting
application. We successfully achieve to harvest maximum output power of 640 pW
in single channel, while the same is significantly improved (by about 100
times) with the use of multichannel microfluidic array (maximum up to 20
channels). We envisage that such ultra-low cost devices may turn out to be
extremely useful in energizing analytical microdevices in resource limited
settings, for instance for extreme point of care diagnostics applications.
