The biggest problem with IoT is batteries. They eventually run out and need to be replaced. One or two is no problem.
But how about replacing tens or hundreds? It would be very troublesome.
Recently, IoT modules that last three to five years by battery are being produced. However, the situation hasn’t changed.
On the other hand, V-GENERATOR is very powerful and robust and, once it’s set up, is semi-permanent and rarely needs to be replaced. Power is proportion to the size. The ultra-compact
V-GENERATOR generates power comparable to a coin cell, while the medium size generates power comparable to an AA battery (power of mill-Watt). V-GENERATOR can produce power in an instant, like the flipping of a switch. As voltage is proportional to vibrations, V-GENERATOR can be used as a sensor. It is also weather resistant and doesn’t require battery covers, making it a simple system. The devices are available in many sizes and for many different purposes.
Vibration Power Generation.
Conventional technology called harvester use piezoelectric elements, electrets, and back-and-forth motion of permanent magnets. The reason they can’t be widely implemented is because they generate low power having poor durability and electrical properties.
To replace batteries, they need to produce more power, be more durable, and last longer. To work as a power source, output resistance is also important. In general, piezoelectric elements and electrets with high output resistance aren’t good as a power source, because it’s hard to get current at the electrical circuit. Furthermore, the devices need to be adjustable and customizable in order to work on a variety of vibrations.
V-GENERATOR’s resonance can be easily adjusted and can be customized to different sizes and shapes.
The cost is also an important factor for implementation. By mass producing magnetostrictive materials, V-GENERATOR will be almost the same price as batteries.
