Energy Harvesting Device
Devices that are mobile or located in remote places cannot rely on fixed infrastructure. When they require a small amount of power and the environment allows it, use energy harvesting to gather its required power.
Ambient Energy, Event Energy-Limited, Event-Based Harvesting
You have a device that needs to be powered. The device needs only a small amount of energy to function. Besides, your use case dictates a specific location for this device which restricts available energy sources. For example, the device has to be mobile, wearable, or in a remote location.
You need to power a device with very little power needs. The device is mobile or located in a remote place. Its environment is stable and predictable.
Location: The device has to be mobile or is located at a remote place. Thus, it cannot be a Mains-Powered Device.
Effort: Replacing or recharging a battery in frequent intervals is too much effort or not possible at all. Thus, using a Period Energy-Limited Device is not an option.
Energy Requirements: The device needs very little energy to function.
Lifetime Energy Requirements: The device needs more energy over its lifetime than current batteries can provide in a reasonable form factor without being replaced or recharged. Thus, using a Lifetime Energy-Limited Device is not an option.
Integrate an energy harvesting component, such as a solar cell, into the device. Use it to turn the energy available in the device’s surroundings into power for the device. Use components and technologies optimized for low-power usage to make the most of the harvested energy.
