Transcript of Research Academy: Sensorimotor Prosthetic Hand

Research, Implementation, and Applications
Sensorimotor Prosthetic Hand
Research is the directed study of a subject in order to learn more about it and develop new ways to solve problems.
What is Research?
1. Literature Survey
The first and most important part of research is reading background information about the subject, materials/parts you will use, and research other people have done that is related to your subject.
2. Specify Requirements
What has been done?
What is being done?
Götz von Berlichingen's Iron Hand Prosthesis ca 1480
What are we doing?
SDSU Prosthetic Hand Mockup
This is the phase where the assembly of the mockup, then the prototype, takes place.
4. Prototyping

0. Define the Problem
Loss of limbs through combat or accident
For example, the strength and durability that is required for your application. A stress strain curve is used to determine the capabilities of the limb by defining the materials' limits.
Applications
After retesting and optimizing the limb based on data and user feedback, it is ready for deployment.

3. Design
Engineers need to carefully plan out what they are going to build.
Research Method
Research follows a certain methodology. There is a sequence of steps required to gain new knowledge.

Development of a Bionic Hand Prosthesis
Our Literature Survey topics:
Anatomy of the hand and forearm
Techniques used for sensory feedback
Prosthetic models currently in use
User's thoughts on their prosthetics
Eskin, a nanowire mesh used for pressure detection was developed at UC Berkeley.
Interdepartmental Cooperation
The Kinesiology Department and the Biomechanics Lab work together to share information, equipment, experience, and expertise.
Conclusion
Prosthetics have improved greatly in the past few decades, but there are still many areas that need to be optimized and improved. The components needed to make a great arm are out there, but they need to be incorporated together. More research is definitely needed, as the field is still in its infancy.
Lab Culture
Every lab has its own culture, but there are certain things that are universal.
Example: Wearing glasses within the engineering shop while engaging machinery
Teamwork is very important: projects are complex and it is far better to divide workloads among a team.
Always document everything.
Our mockup of the robotic hand is a simple design made with Styrofoam, wood, beads, strings, and glue. The fingers were modeled after the human finger, having three bones and three joints (two of each for the thumb). A plastic straw acts as the bones, which is reinforced with wood for stability, and a clear bead acts as the joints. Each finger is capable of flexion by pulling its corresponding string located at the bottom of the forearm.

What is the Research Academy?
The Research Academy is an ongoing effort to introduce community college students to graduate level research through partnerships with local universities. Participants got to go through a week working alongside scientists and engineers engaged in cutting edge STEM research.
Personal Reflections
Overall the Research Academy was a great opportunity to learn about what happens after you graduate, and all the different paths your degree can take you. We highly recommend doing it if you get the chance.
It was great working with all the fancy equipment and even better to be involved in the process of invention. Getting to work with bionics before they are generally available was really exiting because it is like being able to glimpse into our future.
If you are interested, the training materials, presentations, and resources are available on the MESA program website:
