Flexible conductive apparatus and systems for detecting pressure

A compression instrument tourniquet that is responsive to applied external force, comprising:

• a first conductive path that includes a first conductive surface;
• and
• a second conductive path that includes a second conductive surface, a part of the second conductive surface having a conductive contact surface area with a part of the first conductive surface when there is no applied external force, another part of the second conductive surface is separate from another part of the first conductive surface when there is no applied external force,
• wherein the applied external force increases the conductive contact surface area between the first conductive surface and the second conductive surface resulting in an increase in conductivity between the first conductive surface and the second conductive surface.

A variable conductive apparatus responsive to applied external force, comprising:

• a first conductive path that includes a first conductive surface;
• and
• a second conductive path that includes a second conductive surface, a part of the second conductive surface having a conductive contact surface area with a part of the first conductive surface when there is no applied external force, another part of the second conductive surface is separate from another part of the first conductive surface when there is no applied external force,
• wherein the applied external force increases the conductive contact surface area between the first conductive surface and the second conductive surface resulting in an increase in conductivity between the first conductive surface and the second conductive surface,
• wherein the increase in conductive contact surface area comprises additional contact points between the first conductive surface and the second conductive surface.
