InnovationA Unique piezomagnetic energy technology

Exclusive technological innovation

Battery-free and wireless, Enerbee’s technology is extremely efficient at generating electricity from low-speed, low-torque motion where no other technology works.

The Enerbee’s micro-generator is a unique combination of magnetic and piezoelectric materials. The piezoelectric material allows the device to generate energy regardless the speed of motion. The magnetic material, on the other hand, allows the generator to be driven by very low torque movements.

Enerbee’s multi-patented piezomagnetic technology generates a peak of energy every 90° of rotation of the microgenerator. The energy peaks are converted into usable energy via an innovative electronic stage, delivering high efficiency autonomous energy in the range of 1mW to 10mW equivalent to 1.5 to 6 AA batteries per year.

The electricity generated can be directly used to power sensors and make wireless data offload, as often used in monitoring applications.

Some applications require a larger amount of power:

CO2 measurements

HVAC applications

– Long-range communications of intelligent readings.

In this case, energy can be stored in super capacity and redistributed using Enerbee’s optimized power management electronics design.

From energy sources to data transmission

Enerbee’s piezomagnetic technology is used to power sensors ans actuators that can operate in a wide range of equipment
