Outline of Final Research Achievements

he purpose of this research is to develop a smart gear system that can observe the state of gears during operation. Smart gears are gears with sensor and antenna circuits printed with conductive ink on their surfaces. By transmitting information obtained from the sensors to the outside through the antenna, the state of the gears can be monitored without contact during high-speed operation. An observation target side system combining a crack detection sensor and an antenna has been designed and printed on plastic gears so far. By magnetically coupling the system with an observation transmitter/receiver system consisting of an observation antenna and a network analyzer, the system is capable of monitoring the condition of the crack sensor.

機械要素

Academic Significance and Societal Importance of the Research Achievements

機械装置が,自らの完全性自覚し,自身を構成する要素の損傷や劣化を予見する能力を持つことができれば,機械装置の可用性を高度に保ちつつ,保全を効率的に行うことが可能となる.本研究で提案するように,センサを印刷する歯車側に電池等の電源を用意することなく,無線での監視が可能となれば,歯車のみならず高速で運動する機械要素全般がモニタリング対象とすることができ,これまでにない高付加価値を機械要素に持たせることが可能となる.これにより,本研究から派生する応用研究が拡がっていくものと期待できる.
