Technolog for the World为世界科技

Designing Technology for the World Thinking about technology… What is “High-Tech”? What is High-Tech? Real World Limitations Practical Limitations Practical Limitations Human Limitations How can we improve technology design ? Technology Development Inspiration from J.C. Bose Wisdom from the Toy Market Wisdom from Paul MacCready Academic Challenge A New Approach to Design 3 Examples(from our work) Example #1:Car Safety Sensor Side-Mount Collision Warning Sensor for Vehicles Vehicle Safety Sensor low-cost wireless safety sensor for vehicles. 2.4 GHz microwave doppler radar Helical antenna, 15°beam width enables focused detection zone. Analog filters and log amp provides 100 ft detection range. Sensor unit to the driver-side car door could prevent traffic accidents or personal injury to bicyclists and other motor vehicles. Antenna Design Car Sensor Pilot Test Example #2:Plants As Sensors Rich’s PhD Thesis Low-Cost RFID Tags and Readers Present Work Plant Sensors Applications: Environmental Sensing Military chemical/bio field sensors Smart plants in the home Educational tool Chlorophyll Fluorescence Electron Flow in PSI and PSII Chlorophyll Absorption Spectra Chlorophyll Fluorescence Chlorophyll Fluorescence Plant Cam Plant Sensor Demo Plant Sensor Ongoing Work Example #3:Solar Printer Designing Technology Conclusions Visualization method for spatial variation in photosynthesis. IR Camera and light Monitor Motor-car motion is controlled by plant photosynthesis.
