Is it possible, are indefinite operational life and wireless power grids possible? Maybe not for every application, but how about for micro-scale devices? The fact is in situ energy sources like MEMS vibrational and thermoelectric generators can potentially achieve these goals for small footprint system-in-package (SiP) solutions like bio-implantable devices and wireless sensor transceiver network nodes. The key objective is to scavenge sufficient energy from the environment to sustain the micro-power system indefinitely, or at least extend life to practical levels.

this article is interesting, it shows the tip of the iceberg looming in the horizon for future WSN app… but is the commsdesign site that seems really cool for ee minded guys.. wanna see? dig in
