3. TOPICS TO BE DISCUSSED :
What is Quantum Tunneling Composite (QTC)
QTC in brief
About QTC Pills
Advantages of using QTC
Uses of QTC

4. WHAT IS QTC ?
oConductive substance
oInsulator in normal state
oBecomes conductor by
getting pressure

5. WHAT IS QTC ?
• Conductive tiny particles
• Flexible polymer or soft switch

6. QTC IN BRIEF :
• Quantum Tunneling Composite is a new class of electrically
conductive material.
• QTC Material is a patented technology developed in the UK by
Peratech Limited.
• First produced in 1996.
• QTC usually comes in the form of pills or sheet

7. QTC IN BRIEF :
• While in an unstressed state the QTC Material is a near-perfect
insulator.
• QTC pills are magnetic too.
• The sheets are composed of one layer of QTC, one layer of a
conductive material, and a third layer of a plastic insulator.

8. QTC PILLS
• QTC pills are the most commonly used type of QTC.
• Pills are pressure sensitive variable resistors.
• QTC pills can be used as input sensors which respond to
an applied force.

9. QTC PILLS
• Nanoscale conductive particles inside.
• When the material has a force applied
nanoscale particles come closer to
one another.

10. ADVANTAGES OF USING QTC
• QTC material is a pressure/force sensing material.
• Can be formed or molded into virtually any size, thickness or shape.
• Simple and reliable to use.
• Durable - it has no moving parts to wear out.
• Mechanically strong.
• Its conductivity doesnt depends on conductuve particals in the material actuaally
depends on touching.

11. USES OF QTC
• QTC in Keyboards
• QTC in Robotics
• Toys and Games
• Medical Equipment
• Mobile Applications
• Touch Screen
