美國原廠 Conductive Rubber Cord Stretch Sensor+extras（ada0519）
導電橡膠線拉伸傳感器+附件
Measuring stretch forces isn't easy - unless you have some conductive rubber cord! This cord is 2mm diameter, and 1 meter long, made of carbon-black impregnated rubber. Usually this material is used for EMF gasketing, but its also very fun to play with.
測量拉伸力並不容易——除非你有一些導電橡膠線！此繩直徑為 2 毫米，長 1 米，由炭黑浸漬橡膠製成。這種材料通常用於 EMF 墊片，但玩起來也很有趣。
In a 'relaxed' state, the resistance is about 350 ohms per inch. As you pull on it, the resistance increases (the particles get further apart). As you stretch it out, the resistance increases linearly. So lets say you have a 6" piece - thats about 2.1 Kohms. Stretch it to 10" long and now it is 10"/6"*2.1K = 3.5 Kohms. You can stretch the rubber about 50-70% longer than the resting length, so a 6" piece shouldn't be stretched more than 10". Once the force is released, the rubber will shrink back, although its not very 'fast' and it takes a minute or two to revert to its original length.
在「放鬆」狀態下，電阻約為每英吋 350 歐姆。當你拉它時，阻力會增加（粒子之間的距離會進一步擴大）。當你伸展它時，阻力就會增加。假設你有一個6吋長的電阻，電阻大約是2.1千歐姆。把它拉長到10吋長，電阻就是10吋/6吋*2.1千歐姆=3.5千歐姆。您可以將橡膠拉伸至比靜止長度長約 50-70%，因此 6 英吋的橡膠零件不應拉伸超過 10 英吋。一旦力量被釋放，橡膠就會收縮回來，儘管它不是非常“快”，需要一兩分鐘才能恢復到原來的長度。它不是真正的線性感測器，電阻可能因批次而異，因此我們認為它是一種測量拉伸運動的方法，但並不十分精確。
This stuff is fun, so we give you a full meter and also two alligator clips (to connect to the cord) and a 10K resistor. Together, you can use these to make a simple voltage divider. Then use our handy Thermistor tutorial to measure the analog voltage and convert that back to resistance.
這個東西很有趣，所以我們給你一個完整的儀表和兩個鱷魚夾（用於連接電線）和一個 10K 電阻器。您可以使用它們來製作一個簡單的分壓器。然後使用我們方便的熱敏電阻教學來測量類比電壓並將其轉換回電阻。
