Project Outline

Project Outline:

  1. Problem: Lithium batteries
    1. Dependency on batteries and external energy sources has really limited the compatibility of several possible healthcare devices and make it harder for patients to constantly have peace of mind.
      1. Toxic material
      2. Lacks longevity
      3. Heavy
      4. Non-flexible
      5. Nonrenewable
  2. Introduce topic of harnessing energy from human body
    1. How much power the human body holds/is capable of generating
    2. Why this source of energy is better than lithium batteries
    3. Different areas of harnessing power
      1. Movement (piezoelectricity)
      2. Heat (thermodynamics)
      3. Glucose Fuel Cells (Enzymatic Fuel Cells)
  3. Current Technology
    1. Glucose-based fuel cells
      1. The use of glucose enzymatic fuel cells will allow users to use various nanotechnological devices that could allow patients to monitor various portions of the body, allow easier application of medications, reducing the need for constant monitoring and aid from nurses and loved ones.
      2. Explain how they work
      3. Explain the challenges
        1. Interfacing with human body
    2. Specifically Enzymatic fuel cells
  4. Our decision to focus on EFCs
    1. Why we chose EFCs
      1. Because they are the most natural form of harnessing power from the body over the other forms
      2. Take electrons from the glucose in the plasma of our blood
    2. What is the largest benefit of using them over other technology
    3. What are the challenges still
      1. Direct Electron Transfer (DET)
      2. Mediated electron transfer (MET) – finding the right molecule
        1. It has been shown that the correct composition of the molecule mediating the transfer of electrons can idealize the amount of power generated
        2. This molecule must have the right potential to allow electrons to most easily be transferred
  5. Our Technology/ Idea
    1. What it is/how it works…
      1. These are enzymatic fuel cells that oxidize glucose through redox reactions in order to transfer the electrons from the glucose in the plasma in our blood and create an electric potential/electricity.
    2. Why it is better…
      1. Harnesses more energy, faster – more efficient
        1. Is more natural to the human body, working with natural reactions rather than external “hardware” which the body does not simply accept
      2. More power
      3. Has potential to transfer electrons faster and at greater mass than the alternatives
  6. Possible applications for the future
    1. This application could be used in an assortment of nanotechnologies that could be used for patients that are categorized in an array of age ranges.
      1. Patients that are dependent on their blood pressure monitors could have a device implanted that can give constant updates and could alert them and their family members when it reads dangerous levels.
      2. A younger child that suffers from a heart defect or specific infections could use a implanted device to monitor their health without the discomfort or dependency of remembering to charge any device or sit by an outlet for an extended period of time.
