Outline of Final Research Achievements |
Noise of the developed Au-alloy MEMS accelerometer was experimentally evaluated to be below 30 nG/√Hz, and therefore we achieved the target resolution of below 0.1 uG. Long-term vibration test results showed the device functioned even after 10^6 vibration cycles that would usually cause fatigue in metal materials. Temperature test results exhibited the device survived after temperature change from -50 ℃ to 100 ℃. Furthermore, we developed a sensing module with the fabricated MEMS device and demonstrated acceleration sensing on human body. In terms of mechanical strength of Au-alloy, we successfully developed an Au-alloy material with the yield strength of above the target value (1 GPa). In conclusion, the developed Au-alloy device has a promising potential to detect nano-G.
