全球能量收集系统市场-增长,趋势和预测(2019-2024年)
Energy harvesting, also known as power harvesting or energy scavenging, is defined as the process by which energy is derived from external sources. Ambient energy, the source of energy for energy harvesting systems, is present as ambient background and freely available. Different sources of ambient energy include light energy, thermal energy, radio frequency energy, kinetic energy, chemical/biological energy, atmospheric energy, and hydro energy. Among these, solar, thermal, and vibrational energy are the forms of energy that are the most frequently used by energy harvesting systems. Energy harvesting systems typically convert the ambient energy into electrical energy, which is then used to power up various devices, such as consumer electronics, implantable biosensors, wireless sensor nodes, military equipment, etc. Energy harvesting systems are primarily used in low-power electrical utilities, such as sensors, watches, and home appliances. These systems provide an efficient alternative to the use of conventional power sources, like batteries. The use of such energy sources have been particularly advantageous, as the devices can be virtually operated to an infinite amount of time without any adverse affects on the environment. There is high usage of batteries, globally, which is leading to wastage of resources and potentially harmful outcomes for the environment.
