Energy-harvesting-based IoT devices

“

- [Instructor] Energy harvesters generate electrical energy by various methods. To power an IoT device, an energy harvester is connected to a battery management module of the device and provide energy to the electronic components on the device circuit board including microprocessors and the radio modules. There are some common methods that an energy harvester can use to generate energy. First, energy harvesters can generate electric energy from ambient lights such as solar and indoor lights. This method has been broadly used on many battery-less devices such as temperature and humidity sensors. Energy harvesters can also generate electrical power from motions or mechanical strains such as linear movements and vibrations. For example, this method can be used on some end devices that require a linear motion action to trip the radio transmission events such as the light switches and the door handles. Also, energy harvesting-based modules can power the end device mounted on a vibratory…
