Supervisor:

  • Dr. Hossein Rouhani

Research Interests:

  • Biomechanics
  • Biomechatronics

 

PROJECT

During my stay I have worked with two different projects, the first is to create a low-cost foot insole to detect the pressure distribution of a foot during a person’s daily activity. With this technology we pretend to detect any irregular activity, so we can be able to prevent any risk caused for a foot related disease.  The second project is based on a tricycle made for people who are no longer able to move their legs. The tricycle is moved thanks to electrodes that are placed on certain muscles of the patient, and this electrodes send an electric signal according to the current position of the leg, which is detected by an encoder placed on the tricycle’s gear.

For the foot insole project, I used an Arduino as the main microcontroller, and an external IMU to obtain the velocity and position of the patient. The sensors used on the insole were FSR, and these were distributed on the key points of the insole. For the second project, the main equipment used is the Rehabike, which is stimulated with the RehaStim box, and the RehaTrode (rectangular electrodes) made by HASOMED.
