With the advent of miniaturized sensing technology, which can be body worn, it is now possible to collect and store data on different aspects of human activities under the conditions of free living. This technology has the potential to be used in automated activity profiling systems which produce a continuous record of bodily activity patterns over extended periods of time. Such activity profiling systems are dependent on recognition algorithms which can effectively interpret body worn sensor data and identify different activities. The automated recognition of bodily activities (stationary, walking, running, jogging) using body worn accelerometer data is a challenging area of work. In this book existing activity recognition system were discussed. In Existing activity recognition systems suffer from several obvious practical limitations such as the location and nature of sensors that people will tolerate. Other issues include ease of use, discretion, cost, and the ability to perform daily activities unimpeded. The results are getting from the Accelerometers with different subjects are collected through pc and can be analysed by Matlab software by activity variance and DT algorithm.

Micro Electro Mechanical Systems (MEMS) have an extensive use in different areas of technology. Inertial sensors (accelerometers and gyroscopes) are one of the most widely used devices fabricated using MEMS technology. MEMS accelerometers play an important role in different application areas such as automotive, inertial navigation, guidance, industry, space applications etc. because of low cost, small size, low power, and high reliability. This book presents a detailed SIMULINK model for a conventional capacitive sigma-delta accelerometer system consisting of a MEMS accelerometer, closed-loop readout electronics, and signal processing units (e.g. decimation filters). By using this model, it is possible to estimate the performance of the full accelerometer system including individual noise components, operation range, open loop sensitivity, scale factor, etc. The developed model has been verified through test results using a capacitive MEMS accelerometer, full-custom designed readout electronics, and signal processing unit implemented on a FPGA.

Sensors and devices, based on micromachining technology, known as micro-electro-mechanicalsystems or MEMS, have been received increasing attention so far in recent years. Micromachined inertial sensors, consisting of accelerometers and gyroscopes, are one of the most important types of silicon-based sensor. MEMS capacitive accelerometers have been extensively used in automobiles, inertial navigation systems, earth quake detection and many other bio-medical applications. This book deals with the design of a monolithic 3DOF MEMS capacitive accelerometer using both analytical and numerical techniques. Monolithic accelerometer is a single structure having three individual single axis Accelerometers on a single substrate and utilizes a surface micromachining technology using standard PolyMUMPs process. The designed accelerometer is 3mm×3.1mm in size, has low mechanical noise floor, high sense capacitance and high sensitivity along in-plane (x and y) and out-of-plane (z) axes. Performing a detailed finite element analysis in ANSYS 11.o, physical level simulation has been done to verify the deflection for x, y and z axes with respect to the applied acceleration (g).

Robotic arm whose objective is to imitate the movements of a human arm using accelerometers as sensors for the data acquisition of the natural arm movements. This research work is based on the concept of controlling a specific wireless robotic arm using a "portable" controller, which is controlled by a human arm gestures. One of the major ideas behind this project is to introduce the concept of controller portability. In this work the controller is used as an Android app. Even if the controller doesn't have access to the Android device which has the controller app installed, the user can easily download the app and use it in any Android device, which has the following components: Accelerometer, Orientation Sensor and Bluetooth module.
