Environment – Comments from the Developer

More Than Just a Novelty, a Technology that Is Genuinely Useful

The initial spark for this idea came from a particular exhibition. Looking at the sympathetic vibration of the spring portion of a device on display the thought came to me: “Can this be used to generate electricity?” I bounced this idea off of some colleagues, but there were doubts as to whether this could really work. Having generated a certain amount of voltage using a prototype, however, I embarked on a process of trial and error with the cooperation of experts in the fields of electromagnetic induction and material technology. Little by little, we were able to enhance performance. Today, a large number of researchers and engineers are finding this proposal both unique and interesting. While I find this recognition gratifying, I am convinced that the role of a developer is not to merely put forward ideas that people consider a novelty, but to create technologies that are genuinely useful.

Aspiring to Fast-Track Market Introduction of an Initial Practical Application

Wireless sensors that utilize vibration power generation represent a new technology that complements efforts to develop environmentally friendly sensors. Following presentations and announcements during an environmental exhibition held in December 2012, a significant number of companies have responded favorably and are currently promoting joint research into securing commercial application. In addition to measuring vibration data at actual usage sites and customizing optimal power generation mechanisms in accordance with this data, we are looking at designs for both the power generation and measuring components that are capable of minimizing energy consumption. Our goals are to realize an initial practical application as quickly as possible. By introducing a concrete example of this new technology to the market, we anticipate increased awareness by society as a whole and a sudden surge in applications across a broad spectrum of fields.
