The physics behind the WaveHarvester
Energy harvesting from vibration and sound is not new. What is new is making it reliable, compact and cost-effective enough to deploy at scale in industrial environments. Here is how we do it.
How it works
Energy conversion chain
We employ two primary harvesting mechanisms: acoustic transduction for capturing airborne sound energy, and electromagnetic induction for capturing mechanical vibration.
The core of the system is our power management layer. This includes high-precision impedance matching, ultra-low-loss rectification, and specialized cold-start circuitry designed to operate from the micro-watt threshold.
1.
Ambient input
Vibration (mechanical, structural) and airborne sound energy from the surrounding environment.
Input: 20 Hz – 2 kHz (tuneable)
2.
Transducer stage
Proprietary acoustic and electromagnetic transducers convert mechanical energy into raw electrical signal.
Hybrid: acoustic + electromagnetic
3.
Power conditioning IC
Impedance matching, rectification and cold-start circuitry stabilise and regulate the output.
Output: regulated 3.3V or 5V DC
4.
Energy storage
Supercapacitor buffer smooths intermittent harvesting for continuous device power delivery.
5.
Load — powered devices
Wireless sensors, IoT nodes, environmental monitors. Battery-free, continuous operation.
Target: mW – low W applications
