As the sensor is bent, the distance between the particles in the ink increases, which in turn increases the electrical resistance. Because this change is predictable and linear, you can easily calculate the exact angle of a finger or a robotic joint.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e \u003cbr\u003e\u003cstrong\u003eWhy it’s a Motion-Sensing Essential:\u003c\/strong\u003e \u003cbr\u003e• Wearable Integration: At just 2.2 inches long, it is perfectly sized for the joints of a human hand. Its flat, thin profile allows it to be sewn into fabric or taped to skin without restricting movement. \u003cbr\u003e• Simple Analog Interface: Since it behaves like a potentiometer, you don't need complex communication protocols. By using a simple voltage divider circuit, you can convert the bend into a voltage that an Arduino or ESP32 can read through an analog pin. \u003cbr\u003e• High Durability: These sensors are designed to withstand thousands of \"flex cycles,\" making them reliable for long-term projects like physical therapy devices or gaming controllers. \u003cbr\u003e• Passive Operation: The sensor itself doesn't require a dedicated power pin—it simply sits in your circuit and resists the flow of current based on its shape. \u003cbr\u003eTechnical Capabilities: \u003cbr\u003e• Variable Resistance: * Straight: Typically has a \"flat\" resistance (often around 10kΩ to 30kΩ depending on the brand). \u003cbr\u003eo Bent (90°): The resistance can increase significantly (often doubling or tripling the flat resistance). \u003cbr\u003e• Breadboard Friendly: Features a standard 0.1\" pitch connector, making it easy to plug into breadboards or use with female jumper wires. \u003cbr\u003e• Low Power: Because it is a passive component, it only draws as much current as your voltage divider circuit allows, making it extremely battery-efficient.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e \u003cbr\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e \u003cbr\u003eThe 2.2-inch flex sensor is the go-to for hand gesture recognition, VR controllers, and rehabilitation devices. It is most famous for its use in \"Power Gloves\" and DIY robotic hands, where one sensor is placed over each knuckle to track finger movement. \u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"TinkEdge","offers":[{"title":"Default Title","offer_id":46397408051399,"sku":"TE-FLEXS-053","price":533.93,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6620\/6407\/files\/FlexSensor2.2_1.png?v=1776494340","url":"https:\/\/shop.tinkedge.tech\/products\/flex-sensor-2-2inch","provider":"TinkEdge","version":"1.0","type":"link"}
