Soundpower Corporation

We have developed power generators that convert vibration energy into electric energy.

We conduct R&D on energy harvesting technology. This includes vibration force power generation, temperature difference power generation, and vessel-type small hydraulic power generation. We developed the Power Generating Floor®, which generates electricity by using the vibration energy generated by a person walking. We also developed the Vibration Force Cell®, which utilizes vibrations generated when a person pushes a button, and so on.

[Company strength]
We are active in the whole area of energy harvesting technology from R&D to manufacturing and sales. This includes vibration force power generation, temperature difference power generation, and vessel-type small hydraulic power generation. One of the characteristic of our company is that all of the technologies we provide are original, patented technologies.

[Business description]
We conduct research on vibration force power generation using piezo-electric devices. We use this technology to examine and propose methods for utilizing the vibrations generated in people’s social activities (from big vibrations caused by machines, etc., to small vibrations like sound). Our Power Generation Floor® generates electricity by using the vibration energy generated when a person is walking. This is one of our company’s typical products.

[Strength of products/technologies]
We possess patented technology that enables power generation from relatively small energy sources around us. This includes the vibration energy generated when a person is walking, and the pushing force when a person pushes a button on a remote control. We have succeeded in commercializing and mass producing energy harvesting products at an early stage in the domestic Japanese market.

[Representative's message]
We are involved in our core technology of energy harvesting from R&D to mass production in an integrated manner. This field has been gaining recognition in Japan,. We follow a business model in which small multi-purpose power generators are widely applied to various products. These include our typical products such as the Power Generating Floor® and Vibration Power Cell®. We also receive high evaluations in our consulting business, which mainly involves major enterprises. We propose new businesses in the field of energy harvesting from more than 300 types of applications prepared on our list.

[Company structure for market development/overseas expansion]
We are establishing a company system as a select group of experts, strengthening our affiliations with other companies, engaging in capital cooperation with major client companies, etc. We also attach importance to contracts, intellectual property, and compliance. This is done with the cooperation of our legal adviser’s office and advisory patent attorney’s office. We manage our company’s accounting and tax matters under the supervision of an audit corporation in addition to an advisory tax accountant’s office.

[Market share/Ranking]
Power Generating Floor® (floor-type electric power generator): 100% share of the domestic Japanese market.
