Shake It Off

An affordable solution to a life-altering problem.

Our Goal

S.I.O. is focused on helping victims of essential tremor (ET) and Parkinson's disease. ET and Parkinson's both affect motor skills through uncontrollable shaking, or tremors, making everyday tasks much more difficult. The goal of S.I.O. is to develop a device which will counteract the tremors, minimizing the shaking, to allow the individuals to perform the everyday tasks they once enjoyed.

The Solution

How It Works

The design utilizes a gyroscope that is placed on the back of the user's hand. A gyroscope is a disk shaped object that has a mass as far away from the center as possible to maximize the force provided. Torque is given as T = r x m*a, with torque increasing proportional to the radius as well as mass. When the gyroscope is spun on its axis at high speeds, it resists movements in certain directions due to conservation of momentum. While spinning, it contains large amounts of stored energy. If it is moved, the gyroscope will try to compensate for the movement. Using the weight and the speed of the rotating gyro, the angular momentum will cause the hand to stabilize. A DC motor will power the gyro and cause it to spin once a voice command is given. The DC motor will be attached to the glove.

Software

S.I.O uses a dspic33 microcontroller as it's brains. The ADC samples voice from the microphone and compares it to the stored samples in our EEPROM by communicating over I2C. Once a match is made, we go ahead and power our gyroscope via PWM and the accelerometer can communicate data via UART to a PC GUI that will be monitoring the shake. The GUI can also serve as a secondary control by stopping and starting the motor. All the data is logged for future analysis and reference by physicians.
