Latest Patents

Changyao Chen holds a patent for "Frequency and amplitude stabilization in MEMS and NEMS oscillators." This invention comprises a nonlinear micro- and nano-mechanical resonator that can maintain frequency and amplitude of operation for a period of time after all external power has been removed from the device. Utilizing specific nonlinear dynamics of the micromechanical resonator, mechanical energy at low frequencies can be input and stored in higher frequency modes. This approach extends the energy storage capacity of the resonator by using its multiple degrees of freedom. Furthermore, the energy stored in multiple vibrational modes can be used to maintain the resonator oscillating for a fixed period of time, even without an external power supply. This is the first demonstration of an 'autonomous' frequency source that can maintain a constant frequency and vibrating amplitude when no external power is provided. This innovation is ideal for applications requiring an oscillator in low power or limited and intermittent power supplies. Changyao Chen has 1 patent to his name.
