. Angewandte Reviews harvesting will play a critical role in the implementation of novel sustainable micro-/nanotechnology with more flexibil- ity and adaptability. It can also be expected that more sophisticated hybrid energy-scavenging devices that are capable of concurrently harvesting even more types of energy may be developed. 4. Self-Powered Micro-/Nanosystems 4.1. Concept of the Self-Powered MNS The current rapid advancement of micro-/nanotechnology will gradually shift its focus from the development of discrete devices to the development of more complex integrated systems that are capable of performing multiple functions, such as sensing, actuating/responding, communicating, and controlling, by the integration of individual devices through state-of-the-art microfabrication technologies. Furthermore, it is highly desired for these multifunctional MNSs to operate wirelessly and self-sufficiently without the use of a battery, especially in applications such as remote sensing and implanted electronics. This operation scheme will not only extend the life span and enhance the adaptability of these MNSs while greatly reducing the footprint and cost of the entire system, but it will also increase the adaptability of these MNSs to the environment in which they are deployed. As the dimensions of individual devices shrink, the power consump- tion decreases accordingly to a reasonably low level, so that energy scavenged directly from the ambient is sufficient to drive the devices. The concept of self-powered nanotechnol- ogy was first proposed and developed by the Wang research Z. L. Wang and W. Wu group,[7b,c, 25, 108, 137] with the aim of building a system that operates by harvesting energy from the ambient vicinity of the system and converting it into usable electrical power for wireless, self-sufficient, and independent operations. A typical self-powered MNS should consist of a low-power micro- controller unit, high-performance data-processing/storage components, a wireless signal transceiver, ultrasensitive sensors based on micro-/nanoelectromechancial systems (MEMSs/NEMSs), and most importantly the embedded powering/energy-storage units (Figure 12). 4.2. Examples of Self-Powered Sensors and Systems Extending the initial concept of self-powered micro-/ nanotechnology, the Wang research group demonstrated the first integrated self-powered nanosystem on a large scale without an external power supply. Within this system, the NW pH sensor and the UV sensor were driven by an integrated ZnO-NW NG.[110] Self-powered nanoelectronic systems based on discrete core/shell silicon-NW photovoltaic devices have also been demonstrated,[14c] and a DSSC based on high- density arrays of vertically aligned ZnO nanotubes has been investigated as the power source to drive a humidity sensor.[138] Intensive research effort has since been invested in the development of self-powered MNSs, and various prototypes have been reported. A self-powered wireless transmission system composed of an NG for harvesting mechanical energy, a low-loss full-wave bridge rectifier with a capacitor for storing the energy, an infrared photodetector, and a wireless data transmitter was shown to transmit data wirelessly and Figure 12.
