PEH can use in micro and macro system. Is Micro system feasible for PEH for application like medical implant, Wireless Sensor Network or else?
Piezoelectric energy harvesters (PEHs) are indeed devices that can convert vibration into electrical energy. They are becoming increasingly popular due to their potential to power low-power electronics in a sustainable way. There is a growing range of PEH products available on the market, ranging from micro-scale devices for powering wearables to macro-scale devices for powering larger systems.
Here are some examples of commercially available PEH products:
Micro-scale PEHs:
- PowerFilm by EnerChip: These thin-film PEHs are flexible and can be integrated into a variety of surfaces to harvest energy from vibrations. They are commonly used to power wearables, sensors, and other small electronics.
- P21 by Perpetua: This micro-scale PEH is designed to be embedded into devices and harvest energy from internal vibrations. It is well-suited for powering medical implants, wireless sensor nodes, and other low-power applications.
- EMIJ by EnOcean: These micro-scale PEHs are used in wireless switches and sensors to generate the power needed for communication. They are a popular choice for building automation and Internet of Things (IoT) applications.
Macro-scale PEHs:
- Innowave PowerPlates: These macro-scale PEHs are designed to be installed on surfaces that experience vibrations, such as bridges, floors, and wind turbine towers. They can generate significant amounts of power, which can be used to power lights, sensors, and other devices.
- Tyndall SCAPE harvester: This macro-scale PEH is designed for use in railways. It is installed on the tracks and harvests energy from the vibrations of passing trains. The harvested energy can be used to power signals, sensors, and other railway infrastructure.
- APC by APCEnergy: These macro-scale PEHs are designed for use in industrial applications, such as on conveyor belts and production lines. They can harvest energy from the vibrations of machinery and equipment, which can be used to power sensors, actuators, and other devices.
This is just a small sampling of the many PEH products that are available on the market. The best PEH for a particular application will depend on the specific requirements of that application, such as the available vibration energy, the power requirements, and the size and cost constraints.
