The global market for Energy Harvesting System is projected to reach US$651. 5 million by 2025, driven by the growing appreciation of the need to reduce and reuse resources to ease the environmental burden and manage climate change challenges. Energy efficiency is the most important way to tackle climate change and meet sustainable development goals (SDGs). With global energy supply under stress, it`s time to capture and reuse wasted energy. All energy related activities such as cooking, heating, cooling, lighting, transportation results in energy wastages. Energy harvesting offers an innovative way to capture energy wasted during primary energy output. Innovations are underway to develop energy harvesting equipment capable of capturing energy lost in each activity to enhance efficiency of non-sustainable systems. Examples include regenerative braking in cars, dynamic Thermoelectric Generators (TEGs) to reuse energy in smart phones, capturing heat from hot water from heat exchangers in a process plants etc. Energy harvesting systems depend on transducers, energy storage and power management devices for harvesting and storing the energy. Transducers or harvesters collect and convert energy from a source into electricity. Standard transducers feature photovoltaic cells for light, thermoelectric components for heat, inductive components for magnetic, RF for radio frequency and piezoelectric parts for vibrations or kinetic energy. The main energy storage components used in energy harvesting systems are batteries and super-capacitors. On the other hand, power management components condition electricity into appropriate for proper usage. Typical conditioners represent regulators or sophisticated control circuits capable of running the power on the basis of power requirements and available power.

Energy harvesting power management ICs are an integral component of energy harvesting systems. These devices receive low, intermittent energy produced by energy harvesting systems and transform it for storage into dedicated storage devices that can be batteries, capacitors and super-capacitors. The stored energy can be used for powering intended devices with low power requirements. Energy harvesting power management ICs manage power outflow from storage devices and prevent energy usage by a device when it is below the threshold value. Energy harvesting systems leverage ambient light, vibration, motion, electromagnetic radiation or thermal gradients to generate power that can be used by electronic devices. These systems rely on energy storage systems to ensure power delivery when the electricity can`t be produced. These applications often involve the use of rechargeable batteries, also termed as secondary cells. These batteries feature specific rechargeable chemistry like lithium-polymer, nickel-cadmium, or solid-state thin films. The cell chemistry directly influences battery performance limits and metrics. The potential use of free mechanical vibration to power self-sustained wireless electronics, portable devices and remote sensors has established energy harvesting an interesting domain. Researchers are focusing on variable capacitance by using motion of dielectric or water and conductive like mercury droplets to efficiently harvest energy. Ongoing developments in this direction are anticipated to enable researchers to effectively use droplets for harvesting energy.
