Invention Description The demand for advanced thin-film deposition techniques has grown substantially in recent years, driven by the development of next-generation electronic, optoelectronic, and energy devices. Traditional deposition methods, such as chemical vapor deposition, molecular beam epitaxy, and physical vapor deposition, have well-established...

Background Vibration is one of the main causes of performance degradation of precision instruments, vibration noise, failure of structural parts, and human discomfort. In particular, the human body is most sensitive to vibrations in low frequency range especially for the wounded and newborn babies in transit. Thus, effective low-frequency vibration...
