The ion thruster uses metallic ions as the propellant. By using the concept of electron-beam physical vapor deposition processing, a zinc target is bombarded, heated, evaporated,ionized by magnetron e-beam bombardments. Zinc ions are accelerated by an electric fieldthus provides thrusts.

The technology combines specific visual recognitionelectrochemical quantitative detection in a single portable device, providing instantconvenient copper ion detection. The sensing sensitivity has reached the standards of Taiwanthe United States for heavy metal detection for food, human body,environments. In use, this portableuser-friendly interface device not only makes it simple to report back to the EPA database for water quality analysis, but also it can be utilized for real-time detection from youngsters to the elderly.
