英文要約Clean Device Promotion Project, which is aimed to create novel applications of innovative electronic devices through demonstration and standardization/Energy harvesting device implementation project for disseminating energy saving sensor systems (FY2014-FY2015) FY2014 Annual report

Utilization of sensor systems has a large energy saving potential. However, trouble with the power supply including battery replacement or wiring between power and sensors prevents diffusion of sensor system. Utilizing “Energy harvesting device (innovative electronic device)” enables a sensor without outside power supply. A sensor without outside power supply facilitates promotion of sensor system; contributes to the solution of social problems include energy-saving.
This project reviews three use-cases; 1. Energy saving promotion at offices and factories, 2. Loss reduction by fault prediction of rotating machinery, and 3. Fuel efficiency improvement applying tire pressure monitoring system.
With these use-cases, long-term stable operation of sensor system applying environmental power generation device has been validated. Basic data collection, implementation guideline formation, international standardization proposal, etc. for environmental power generation device will be proceeded for promotion.
The projects includes following three phases;
a. Creation of use-cases
b. Implementation and validation, and
c. Efforts for standardization, safety and reliability.
a. Creation of use-cases
Interviews to potential user and specification consideration on the sensor system utilizing “environmental power generation device” which enables sensor without outside power supply have been conducted in above three use-cases. Product and service will be modeled on the interview and specification; the business plan and framework will be considered.
b. Implementation and validation
For the use-case 1. and 2., an office and two factories were selected for validation; their power generation environments have been measured. An independent power generation module which includes energy harvesting device, power management circuit and storage device has been prepared corresponding to wireless sensor’s electricity consumption. A test wireless sensor product with environmental power device will be validated for long-term stable use.
For the use-case 3., interviews to potential users and specification consideration on a tire pressure monitoring system operating without outside power supply have been conducted. Vibration/impact measurement environment has been prepared; data generated at tires have been collected.
c. Efforts for safety, reliability and standardization.
An experts committee has been established. The committee has examined standard testing method for vibration energy harvester; has considered methods for sine curve excitation test and impact test; and has tested more than two vibration energy harvesting devices. An independent power design and implementation guideline will be prepared for international standardization.
