environmentalenergy using a semiconducting nanowire array Used to
detect chemical and biological agents Problem: Current sensing
platforms require an external powersource (e.g. battery) to operate
Larger dimensions Solution: Harvest energy from the surrounding
environmentLawrence Livermore National Laboratory LLNL-PRES-5651127
8. Converts chemical energy into electrical energy External power
source (such as a battery) iseliminated, reducing bulk and weight
Nanosensor responds selectively to a variety oforganic molecules
(e.g. ethanol, etc.) Yields response times of faster than 1 second
Heat from surrounding environment can beharvested to power the
detectorLawrence Livermore National Laboratory LLNL-PRES-5651128 9.
