2 Phase 3 Hussain Almosa Karen Littlejohn Joey Nirschl Hassan

3 For the Science Center, our client is looking for interactive workstations that would demonstrate to the audience how the concepts from the ECpE curriculum at ISU can help solve real world challenges to assure a better and more sustainable future.

4 Any visitors to the Computer, Electrical, and Software Engineering departments. Perspective Students Alumni Company Representatives Outreach events

5 Piezoelectric Floor - To demonstrate that we can harness the mechanical energy from unconventional sources, such as people, in the form of electrical energy Sequential Programming - To demonstrate and create more understanding of the concept of programming

6 Focus: Energy Sustainability Approach: We will build an interactive floor that utilizes the concept of piezoelectricity to demonstrate to the audience that we can capture mechanical energy from our bodies to generate clean, renewable electrical energy.

7 Key Functional Requirements: The floor shall generate enough current to power a small LED bulb The floor shall support a weight of up to 250 lb The floor shall be raised from the room floor

8 Key Non-Functional Requirements: The floor shall be able to be moved to another room if needed The displays shall be visually appealing The floor module shall be quickly understandable and easy to use

9 Mechanical Stress Tile Displacement Piezo Generator Compression/ Decompression Electrical Power Display Operation User

10 Floor with Separate Visual Display Blocks with Built-In Audio- Visual Display

11 Floor with Separate Visual Display Pros Suitable for wider audience Supports different display options Cons Captures less energy Less interactive Display is disconnected from floor Blocks with Built-In Audio- Visual Display – Pros More interactive Captures more energy Compact system – Cons Not suitable for some audience segments Does not support other display options Potentially hazardous

14 Tiles Compression System Subfloor Piezo Generators Audio-Visual Display Electrical Circuitry

15 Lexan Polycarbonate Sheets Clear Durable Vendor: Ridout Plastics

16 Two Alternatives Spring System Advantage: Could be mounted firmly to subfloor Foam Blocks Advantage: Smooth Compression/ Decompression

17 Wooden Subfloor Divided into 9 blocks Center block will be covered and will not be compressible Each of 8 block surrounding blocks will be compressible and will house piezo generators, compression system, audio-visual displays, and accompanying circuits

18 Vendor: Noliac Inc. Ceramic Multilayer Generators (CMG) are built up with a number of thin ceramic layers sandwiched between internal electrodes, resulting in a low output voltage but high current compared to conventional single layer piezoelectric generators. Custom Product Worked with similar team in Denmark to successfully generate 0.13µA by applying hand pressure to 4 piezo generators. CMG size: 5mmx5mmx2mm, 60V.

19 Visual High Brightness Color LED Vendor: Kingbright USA 120°viewing angle Luminous Intensity: Available in blue, green, and red Operating current: 120mA Audio One Central Speaker Powered separately Pre-Programmed Sound Modules Vendor: Zhen Xiang

20 Each of the 8 block will house one generator/ display system, which will require separate circuitry. Currently communicating with Noliacs R&D department to determine number, sizes, appropriate circuits, and estimated cost of piezo generators required for our application

21 Structural Analysis Test cell structure for ability to support maximum weight Functional/Performance Testing Test functionality and performance of all 8 piezo generators and audio-visual displays by placing weights on each cell

22

23 Key Functional Requirements: The Programming Module shall allow the user to order a set of commands The Programming Module shall give feedback on command order upon request The Programming Module shall allow the only administrator users to configure the volume used by the module

24 Key Non-Functional Requirements: The Programming Module shall be user friendly The Programming Module shall be quickly understandable and easy to use without a demo The Programming Module shall give the user a taste of programming
