i need to know what a smart material is? any ideas?

Question

google doesnt work and most websites are boring which make me full asleep

Answer 1

My SMART ANSWER:

An Objective in Business or Biology or any matter have to be SMART, that is

S: Specific
M: Measurable
A: Acheivable
R: Realistic
T: Timed

Hope it's in the right Context

Answer 2

The first answer is very comprehensive. As a real life example, do you or your friends have braces on your teeth? If so and it's early in your treatment, the wire going through the brackets is probably nickel-titanium and this is an example of a Shape-Memory Alloy. When your teeth are all over the place the wire has to bend in all different directions to fit in the brackets and this can be difficult with normal stainless steel wires. The Ni-Ti wires are flexible at cooler temperatures but when your body heat warms them up, or you drink a hot drink, they stiffen more. The advantages are that the same wire can be used for longer and it hurts less!

Answer 3

.Smart materials are materials that have one or more properties that can be significantly altered in a controlled fashion by external stimuli, such as stress, temperature, moisture, pH, electric or magnetic fields.

There are a number of types of smart material, some of which are already common. Some examples are as following:

Piezoelectric materials are materials that produce a voltage when stress is applied. Since this effect also applies in the reverse manner, a voltage across the sample will produce stress within the sample. Suitably designed structures made from these materials can therefore be made that bend, expand or contract when a voltage is applied.

Thermoresponsive materials, either shape memory alloys or shape memory polymers, are materials that can hold different shapes at various temperatures.

Magnetic shape memory alloys are materials that change their shape in response to a significant change in the magnetic field.

pH-sensitive (halochromic) materials are commonly materials that change their colour as a result of changing acidity. One suggested application is for paints that can change colour to indicate corrosion in the metal underneath them.

Chromogenic systems change colour in response to electrical, optical or thermal changes. These include electrochromic materials, which change their colour or opacity on the application of a voltage (e.g. liquid crystal displays), thermochromic materials with color depending on their temperature, and photochromic materials, which change colour in response to light - for example, light sensitive sunglasses that darken when exposed to bright sunlight.

Answer 4

smart material would be something that has the ability to change shape and return back to its original shape. Like lykra or polyester can stretch but it returns back to the original shape.

According to wilkapedia: Smart materials are materials that have one or more properties that can be significantly altered in a controlled fashion by external stimuli, such as stress, temperature, moisture, pH, electric or magnetic fields.

Answer 5

A smart material is one that has a memory and sometimes reverts back to its original form, i.e. chocolate gets melted down in a glass bowl over a saucepan of water if its left too long it will revert back to solids. i think this is one example i hope it helps.

Answer 6

A smart material is one that can change as needed in response to its environment.

Answer 7

smart materials have one or more propertys that can be altered by outside factors. like sunglasses that darken in sunlight.

Answer 8

It's hard to understand in which context you are posing this question, but how I am taking it suggests a material which conforms to its use without manipulation.

Answer 9

It can change shape and then go back to it's original shape.
Example - Elastic, some plastics, knife blades..etc.

Answer 10

the one that breathes when needed, is waterproof during rainy days and protects you against UVA and UVB on sunny days
