Design and Development of a Wireless System to Measure and Transmit Vital Body Gestures Using Bend Sensor Array and MEMS Sensors

The objective of the proposed work is to design and develop a microcontroller based hybrid system to identify and measure the vital body gestures including hand gestures using bend sensor array along with MEMS sensors and send these signals through a wireless media. The bend sensor arrays employ flex sensors and in MEMS we have exploited the accelerometer characteristics. These sensors are wearable in the form of gloves which will help produce signals corresponding to different hand gestures and finger movements. The system is made to read these signals and after signal conditioning processes the digitally converted values are compared with the user predefined values to identify specific hand gestures. The system was built around a widely used eight bit microcontroller. The 8-bit multiplexed channel Analog-to-Digital Converter was interfaced to the microcontroller for the signal conditioning purpose.
