Piezoelectric Power Generating Energy Harvesting Floor System
Piezoelectric Energy Floor
The piezoelectric energy floor is to convert kinetic energy of people’s footsteps to electrical power by using the positive effect of piezoelectric materials.
The energy floor is very efficient energy converting pedestrian floor system which can be installed in pavements and areas with large flow of peoples like airports, sport arenas, shopping malls , dance club, parks, museums etc.
This energy floor enables people to generate their own local clean energy to power street lights and signing systems. It also can be integrated with solar and wind power to create sustainable power source.
After 5 years of continuous of efforts in R&D, we have developed the third generation of piezoelectric floor applicable for outdoor use.
1. Main Features
With humanized design, only minor downward motion of 1mm, no sinking feeling
High energy conversion efficiency and sensitivity, suitable for people of all ages
Tempered glass top sheet, strong and durable
With multiple protections, reliable and long service life
Modular structure, sealed with silicones, waterproof and anti-aging
Easy to install and clean, low maintenance
Integrated LED lights is available
2. Specifications and Applications
The outputs of piezoelectric energy floor vary with pressure.
Output voltage: 0<V<65V
Output current: 0<I<100MA.
Output power: 2-6W (an adult of 60kg per step)
Operation temperature: -40°C/+50°C
Currently we provide 3 standard energy tiles:
600*600*25mm
500*500*25mm
400*400*25mm
The size can be customized
The general hardware and software are available.
Because the piezoelectric energy floor generates instantaneous power, there are 2 general applications:
2.1 To power LED lights, for example, emergency lighting and corridor guide lighting etc.
2.2 By connecting with power harvesting system, the small power produced by the piezoelectric energy floor can be harvested and stored to drive some low power devices like the wireless sensor, wireless transmitter for security alarm or traffic statistics etc.
The figure above shows the diagram of power generation and data collection of the piezoelectric energy generating floor system. At present, each floor has 2 ports. The ports are identical for power transfer.
However, each port can only be connected to one type of load. For example, if port 1 is connected to LED light, then it cannot be connected to data collector, which must be connected to port 2.
3. Configuration and Characteristics
The piezoelectric energy floor is composed of 4 parts, top tempered glass sheet, silicone pad, power generation modules and PVC base plate.
Figure 1 shows the principle of piezoelectric energy floor, which produces power in the process that people step on it and power is generated by piezoelectric ceramic elements embedded in the tiles.
Figure 2 shows the first generation of piezoelectric energy floor.
Figure 3 shows the 2nd generation of piezoelectric energy floor.
Figure 4 shows the 3rd generation of piezoelectric energy floor with modular structure, silicone sealing technology, and tempered glass top sheet. It is featured easy maintenance, waterproof, anti-aging and long service life. Therefore it becomes the typical kinetic energy harvesting product applicable for both indoor and outdoor use.
