NEUROPROSTHETIC FOR DIABETICS
Key Terms•Edges:
The wires in an electrical circuit which provide connectivity
•Feedback:The output’s process from a system
•Neuroprosthetic:Prosthetic using a combination of neuroscience
and biomedical engineering•Nodes:
The main components of a system
Key Terms•Peripheral Neuropathy:
Disease or dysfunction of peripheral nerves causing numbness or weakness
•Prosthetic:An artificial body part
•Spikerbox:A device to analyze the neural response of stimulating
a cockroach leg•System:
A set of connected components forming a complex whole
The Need•People with diabetes lose feeling in feet which is known as peripheral neuropathy
•Neuropathy:-Four types (peripheral, autonomic, proximal, and focal)-60-70% of diabetics have some neuropathy-Stems from high blood sugar for too long
The Need•Peripheral Neuropathy:-Damage to peripheral nervous system (transmits info from brain/spinal cord to every body part)-Commonly affects legs and feet-Prone to increased risk of foot problems-Causes damage to nerves which allow feeling of pain-Symptoms (tingling, numbness, or burning)
Solution•Neuroprosthetic:Sock designed to help diabetics suffering from peripheral neuropathy to regain sensation of pain in their feet *No neuroprosthetics currently exists that address this problem*
•Features:-Custom fitted-Restores sensation of pain-Wireless connectivity b/t sock and electrode array-Information syncs with smartphone
PrototypeBluetooth sender
Force sensors
Electrode Array w/ Bluetooth receiver
Compression Sock•First Creation:
Made in 1920’s by Bauerfeind family company in eastern Thuringia (federal state in central Germany)
•Adoption in US:Americans began wearing it more in 1950’s
due to health benefits•Adoption Around the World:
European governments would pay for citizens who needed the benefits of compression sock therapy to avoid future health problems
High-Tech Arm Sleeve•Function:
-Helps coach basketball players in increasing the accuracy of their shots
-Sleeves are packed with sensors that track their movements for analysis on a computer
•Creators:-Vibrado
•Similarities:-An external neuroprosthetic with sensors to assist in tracking information
Neuroprosthetic vs. Spikerbox•Inputs: Force sensor, stimulation•Outputs: Sense of pain, sound•Nodes: Force sensor , Bluetooth sender/receiver,
electrode array
Cockroach leg, speaker, battery, spikerbox electrodes and wires
Arduino SystemBreadboard
Force Sensor
LED
Arduino
Arduino System•Input: Force sensor•Output: LED light•Nodes: Wires, resistor, force sensor, LED, Arduino, and breadboard•System: Arduino system as a whole•Subsystem: Force sensor, LED, Arduino, and breadboard•Edges: Wires•Equilibrium: Resistors (balance current)
Neuroprosthetic System•Disruption: Diminished sensation of feeling in legs and feet•Feedback: Sensation and reaction to pain
Advancements in Prosthetics•Sensor Integration - There is a need for integration of technology into compression socks, similar those in the arm sleeve
•Waterproof Design- The sock needs to have some plastic cover to encapsulate the sensors to prevent water from reaching it
•Bluetooth Electrode Array- Build bluetooth receiver into electrode array (focus on security)
Ethical Issues•Electrode Array – Invasive technology in human organ•Threat to User’s Privacy – Potential harm if technology is hacked or user’s logged data is stolen
•Cost – Too expensive for diabetics in developing countries•Insurance – Insurance companies not covering the full cost of the prosthetic
•Religion – May interfere with the religious beliefs of people about altering someone’s body
Addressing the Issues•Electrode Array – Informing users about all potential threats and making them sign consent forms
•Threat to User’s Privacy – Ensure that user has choice to have data logged and encrypt software and technology to make it difficult to hack
•Cost/Insurance – Create government programs to assist insurance companies and people to cover the costs
•Religion – Depending interpretation of what their religion says about altering the human body, must make their own decision
