Research on Non-linear Vibration in Micro-machined Resonant Accelerometer

Shuming Z., Yunfeng L., Fan W., Jingxin D., Tsinghua University, CN

This paper analyses the non-linear vibration of the Silicon Oscillating Accelerometer (SOA) by system modeling and simulation, and the optimization designation to weaken the influence of the nonlinear vibration are proposed. With the decreasing of [...]

Fetal Movement Detection Based on MEMS Accelerometer

Minjie L., Yongkang T., Yunfeng L., Song Y., Jingxin D., Tsinghua University, CN

Fetal movement is a significant indication of fetal well-being. Standard clinical fetal monitoring technologies include ultrasound imaging and cardiotocography. Both have limited prognostic value and require many health resources. We have recently developed a low-cost, [...]
