Reducing the usage of the fossil fuels and exploring different eco-friendly resources and energy are in highly valued. The abundant mechanical energy is the most promising source of accessible alternative energy in our daily lives. Harvesting energy from bodily movements such as running, jogging, shaking, and so on enabled to power low-power electronics using nanogenerators (NGs) and has recently emerged as an important area of study due to their diverse applicability in practical scenarios. To obtain highest mechanical energy optimization and greater voltage outputs from NGs, scientists all over the globe have put forward potential options of hybrid NGs with numerous and unique designs utilizing a combination of more than one of the following pyroelectric, triboelectric, piezoelectric, thermoelectric, and other NGs. In large-scale operations, hybridization of NGs has proven to be an effective approach for mechanical energy harvesting and sensing applications. This book chapter focuses on major types of NGs for energy harvesting, such as piezoelectric NG (PENG), triboelectric NG (TENG), and hybrid NGs. The emphasis is primarily on the fundamental working mechanisms of three types of NGs, newly developed materials, and typical applications for energy harvesting in fields such as wearable and human monitoring, implementable devices, and artificial intelligence. Finally, we summarize recent advancements in this field and describe future opportunities for improving energy harvester performance.http://purl.org/coar/access_right/c_abf2Advanced Sensor and Energy Harvesting MaterialsInnovative Energy Harvesting TechnologiesFerroelectric and Piezoelectric MaterialsBook Chapterhttps://doi.org/10.1088/978-0-7503-5492-9ch12
