dissipation and is defined as the ratio between the mechanical energy accumulated and dissipated per vibration cycle. Under liquids environments, the quality factor shifts toward much lower values than in air, due to the damping effect of the viscous surroundings, which decrease abruptly the overall sensitivity. For that reason, this way of operation is more difficult to implement and, until rece

Supplying energy for stable is the basis of national survival and economic growth. So this is very important.
Fuel cell is worthy of notice other alternative energy.
It generates electricity inside a cell through reactions between a fuel and an oxidant, triggered in the presence of an electrolyte.
Fuel cells are direct energy conversion into electricity. So High electric conversion eff

정전기(ESD)란?
전기중 흐르지 않고 정지된 전기가 정전기이다.
정전기는 양전하나 음전하가 한 곳에 몰려 있는 전기이다.
정전기는 부도체가 전자를 잃거나 얻음으로 대전될 때 부도체 표면에 생긴다.
정전기는 주로 두 물체간 마찰이 발생하면 한 물체는 Positive(양)의 전하가, 다른 한 물체는 Negative(
