Shape Memory Polymers Written by: M Jason Parent

First introduced in Japan and then the United States 1984¸ shape memory polymers are polymers whose qualities have been altered to give them dynamic shape "memory" properties. Using thermal stimuli¸ shape memory polymers can exhibit a radical change from a rigid polymer to a very elastic state¸ then return back to a rigid state again.
Modern variations on the classic turn-of-the millennium shape memory polymers react to other stimuli than heat.
By the late 2020's¸ SMP characteristics can be engineered into almost all polymers¸ allowing for automobile fenders to be bent back into shape with the application of the right amount of heat; the creation of multiform solid-state furniture that shifts to accommodate different users with the press of a button; and a million other household uses. Some low-rent apartment buildings even use piezo-activated SMPs for the doors on their units so the door can be quickly ‘melted' with the application of a simple stun-gun-like device.
This short PDF presents over 20 different pieces of equipment¸ weaponry¸ armor and day-to-day items that have been made possible due to the 21st Century miracle of shape memory polymers. From knives that change form once inside the victim to new state-of-the-art skateboarding gear.
