The purpose of the project is to design a sensor that can analyse the pressure while writing and simultaneously detect the direction of hand movement. The main principle involved in the designing of the sensor is whenever the sensor will undergo a pressure while writing, electrical output will be produced which will be converted to a certain voltage. This voltage will be directly proportional to the pressure and will be displayed by using a PC, an accelerometer will be employed with the sensor to measure the speed and direction of the hand movement while writing. The accelerometer is an electromechanical device used to measure acceleration forces that might be static like the continues force of gravity or as in the case of many mobile devices, dynamic to sense movement or vibrations. This are actually MEMS where the displacement of a small proof mass etched into the silicon surface of the integrated circuit is suspended by small beams. The main aim of this project is to detect movement disorders of aged individuals at an early stage. According to current report the aged individuals from the age group of 60 and above faces hand movement disorders. So to curb this problem at an early stage a sensor based pad is develop which will analyse the pressure that should be possess by the age group of 60 and above by comparing with the normal individuals of that age group with the help of medical data.
