Step 4Setup
This setup demonstrates how that applying pressure to the touch pad changes the brightness of the LED.
- Connect one of the (sticking out) Stretch conductive layers to the + pole of your energy source (4.5 Volt)
- Connect the + pole of the LED to the other (sticking out) Stretch conductive layer
- Connect the - pole of the LED to the - pole of your energy source
- Apply pressure to the touch pad
The amount of current changes depending on the amount of pressure to one point and the area of pressure.
- Connect one of the (sticking out) Stretch conductive layers to the + pole of your energy source (4.5 Volt)
- Connect the + pole of the LED to the other (sticking out) Stretch conductive layer
- Connect the - pole of the LED to the - pole of your energy source
- Apply pressure to the touch pad

I am looking into this topic for the creation of pressure sensitive mats which I can place in the desert sand next to some surplus company assets which are being stolen for their scrap or salvage steel weight, at about 11 to 1,200 pounds each. So I create these mats, from a rubberized, water and element proof material, and place them and cover them over with about an inch of sand -- and when a criminal approaches their target to hook it up to their portable hoist -- they compress the mat and complete the circuit = which is connected to either a loud siren and intense strobe light, etc. Or even some sort of non-lethal concussion device which is also buried in the sand next to the asset, and with respect, either the Security personnel is alerted by the noise, and or, the bright light(s) -- or the criminals can no longer perform their work on the private property in which they have NO UNDERSTANDING of the concept of; *Keep Out* *No Trespassing*, etc. = so they stumble away trying to figure out what just happened to their sorry butts.
Now, I would normally go with an attached trip-wire to set off one or the other types of support devices -- but the difficulty there is in lifting the asset and finding a place to tie the wire up in a way in which no one can easily see it and disarm it before moving the asset; so the pressure mat does Not have to be attached, and can be completely covered by the natural desert materials, and can be placed where the criminal can't even lay his hands on the asset before setting OFF the switch that completes the Security protection circuit. And on the other side of the coin; the circuit can trip a Silent alarm which brings me out to make the Arrest while they are still working on their theft. That one is my favorite, over circuits and systems that will only scare them off. The Arrest(s) make more noise on the local news and has the possibility of warning other criminals or crews that the risk of capture is just too great in a particular territory.
So there ya go. An example use of the concept, if not the actual materials mentioned in this article. I'll most likely locate, or create my own conductive materials for the pressure mats I require to put a stop to the near constant criminal attacks in my territory. Any existing products already on the market are absurdly over-priced which knocks those sellers right out of our security budget.
Thanks for your time.
Does that make it any clearer???
