In modern times, we have contactless credit cards that allow us to transfer payment when placing a card within a few inches of a payment terminal. But what if there was a more secure way to transfer payment by using the conductivity of our body tissue to our advantage? Human body communications is a signal transfer technique that allows us to send a signal through conductive body tissue, with the signal travelling from a transmitter on the body to a receiver elsewhere. This has many possible applications including, but not limited to, payment technology, implanted medical devices, wearable devices, and authentication applications.
The student handout will be given to all students working on the design challenge. It gives a brief recap of the story, it helps the students identify what they are attempting to achieve, and it recaps the design process.
This Facilitator Guide provides the instructor additional information on how to run the design challenge with alternatives for materials and test setups as well as information to help make the design challenge a good educational experience. In addition there is are three PowerPoint files. One with instructions and review. Plus PowerPoints for the Telling the Story and Design Challenge videos below.
The Telling the Story Video conveys the societal impact of the student’s research that is the basis for the design challenge and will set the problem-solving context for students.
The Design Challenge Video leads students through the design process. It indicates materials available, states what the criteria are for success and any constraints. It also gives a second ‘level’ of the design challenge that allows ‘early completers’ to move on to a slightly more difficult challenge.
