Lifetime Energy-Limited Device
Devices that are mobile or located in remote places cannot rely on fixed infrastructure. When they require a small amount of power and need a robust construction, use a built-in power source.
You have a device that needs to be powered. The device needs only a small amount of energy to function.
You need to power a device, which requires a small amount of power. The device is mobile or located in a remote place. You want to minimize maintenance.
Mobility: The device has to be mobile, thus, being a Mains-Powered Device is not an option.
Location The device may be placed in a remote location far of the grid, where common infrastructure such as powerlines are not available. Thus, being a Mains-Powered Device is not an option. The location may also provide no suitable form of ambient energy for an Energy-Harvesting Device.
Maintenance: A Period Energy-Limited Device is not an option because replacing or recharging a battery in frequent intervals is too much effort.
Energy Requirements: Being an Energy-Harvesting Device on its own is not an option, because it does not deliver the required power.
Lifetime: You know the maximum lifetime of the device.
Ruggedness: The device is intended to be used in environments where a rugged device enclosure is needed.
Build an energy source into the device, which will last for the entire expected lifetime of the device.
