With the rise of the Internet of Things (IoT) and sensor network, the personalized wearable electronic sensing system possessing multi-modality and multi-functional has become the major tendency. However, with the increased functionality of wearable electronic devices, traditional power supply from batteries have encountered great challenges. Hence, how to provide an effective and stable power supply for the design device and system to sustain and endure also receives great attention. Nanogenerators, by extracting mechanical energy from the environment and converting it into electrical energy, such as elbow stretching, knee stretching, walking, tapping and other human actions, the converted electric energy can even directly drive the light-emitting diode. More importantly, the source of mechanical energy is sustainable, pollution-free, highly sustainable, holding great promise for an alternative energy source for next generation wearable electronic systems. In this chapter, we will introduce the fundamentals of nanogenerator technology, including material selection, component design, and system integration. Furthermore, in order to meet up with the requirement of thinner, more diversified, and highly sensitive future electronic systems, the low-dimensional nanomaterials are explored as the candidate materials, and briefly discussed to understand their potential of practical applications.
