We report the fabrication of the first generation batteryless sensors that use one-dimensional semiconducting nanowires. These nanosensors take advantage of a unique interaction mechanism between chemical species and semiconductor nanowire surfaces that induce an electric potential between the two ends of nanowires or between the exposed and unexposed nanowires. The nanosensors have fast response time (better than 1s), relatively high sensitivity and don’t require external power.
