The e-skin Hub transmits all signals from the e-skin via Bluetooth.
Users can recharge the Hub through the Micro USB port at the bottom of the right part.
Green and red LEDs on the left part represent Bluetooth connection and battery information, respectively.
The effective ranges of the sensors in an Inertial Measurement Unit (IMU) are set as -4[G] to +4[G], where G is the gravitational acceleration, for the accelerometer and -2000 [dps] to +2000 [dps], where dps means the degree per second, for the gyro sensor.
Users can separate the body movement into upper body and arm parts because the IMU module and the strain gauges are individually put on the e-skin.
