SMART Materials: Top Trump Cards YOUR TASK is to produce a set of 5 cards, one for each SMART material. Each card should show the following Properties Examples of use Reasons for use Improvements on traditional materials SMART Materials: Shape Memory alloy Properties: Bendable, it will return to its original shape if heated above a certain temperature Examples of use: Sprinklers in fire alarm systems, spectacle frames, coffee machines. Reasons for Use: It’s easily shapen and keeps its shape Improvements on traditional materials: Glasses had to be re-bended by hand but now you can use heat INSERT PICTURE(S) HERE SMART Materials: Shape Memory polymer Properties: Will return to its original shape if heated above a certain temperature. A good insulator. Examples of use: Window sealing foam, sensors and robots Reasons for use: Strong, low cost, can be triggered by temperature and light Improvements on traditional materials: Can be tailored to a broad range of materials and temperatures. INSERT PICTURE(S) HERE SMART Materials: Piezoelectric actuators Properties: When electricity is applied to a Piezo Actuator it changes shape by an small but amount. They can be “stacked” Examples of use: Controlling hydraulic valves, adjusting machining tools and some motors Reasons for Use: Very small and precise movements, no motors or gears to go wrong. Improvements on traditional materials: Easy to control pumps and valves. Very small & controlled movement unlike motors INSERT PICTURE(S) HERE SMART Materials: Piezoelectric transducers Properties: When under impact they create a small electrical current. When electricity is applied they move a small amount. Examples of use: Guitar hero drum sensors. Touch sensitive surfaces, engine sensors Reasons for Use: Reliable and sensitive way of creating an electrical signal from movement or vice versa. Improvements on traditional materials: Small movement needed unlike switches. Simpler than a motor for small movements INSERT PICTURE(S) HERE SMART Materials: Electrochromic materials Properties: Change colour when electricity is applied Examples of use: Smart windows, electrochromic mirrors and electrochromic display devices Reasons for Use: Privacy in office windows, automatic tiniting of windows depending on sun Improvements on traditional materials: Usually you have to choose the colour of a material and it can’t be changed easily INSERT PICTURE(S) HERE Links to help: ize/design/electronics/materialsrev5.sht ml cleID= ogue/ProductDetail/shape-memory- polymer?productID=6ef6577e-aee fe2b &catalogueLevelItemID=4 e3da e-4854-b42e- a7c46e ochromic-windows.html theory/actuators.html ed.org/EducationResources/Community College/Ultrasonics/EquipmentTrans/pie zotransducers.htm And Wikipedia of course but keep it simple.
