Mechanical Energy Harvester for Smart Shared Bicycle Application

The human body-related movements contain ultralow frequency characteristics, and energy harvesters at ultra-low frequency have received extensive attention in energy harvesting. Bicycles are one of the common transportation modes in cities, but the energy supply for devices such as smart locks on the shared bicycles is a challenging task. By combining ultra-low frequency energy harvesters with the motion of riding a bicycle, milliwatt-level energy output can be continuously generated. And through attaching micro-sensors, the shared bicycles can become a self-supplied mobile sensing node.
