Abstract :
The micro inertial measurement system (MIMS) integrates measurement, sampling, quantization, coding/compression, and storage. It can be used in the measurement of dynamic data in rockets, missiles, and vehicles. It can also monitor, collect, and record data from the human body and ambient environment, and then provide output to a hard disk through a computer interface. These data will later be used to analyze human health. MIMS, which comprises a micro electronic mechanical system (MEMS) transducer, a signal acquisition module, a data compression module, a control circuit, and memory can be used in a variety of applications with different environments and requirements. Volume, cost, and reliability are some of the design variables that we considered. Our research on the MIMS includes a single-chip accelerometer and angle-rate transducer, a novel attitude algorithm and its ASIC, and buffer technology for high-acceleration overload
