2.2" Inch Bend Flex Sensor

2.2" Bending Sensor – Flexible Bend Sensor for Motion Detection and Wearable Tech

The 2.2-inch Bending Sensor is a highly sensitive and durable flex sensor that converts physical bending into a measurable resistance change. As the sensor bends, its resistance increases—making it ideal for real-ti ...me motion tracking in wearable electronics such as smart gloves, robotics, gaming controls, and biomechanical feedback systems.

Key Features & Benefits:

📏 Length: 2.2 inches (73.66mm) – perfect for compact and embedded applications

⚡ Responsive Output: Resistance increases with the degree of bend (up to ~60KΩ)

🔁 High Durability: Tested for over 1 million bend cycles

🌡️ Wide Operating Range: Works in environments from -35°C to +80°C

🔌 Easy Integration: Standard 2-pin interface (0.1" pitch) for Arduino, Raspberry Pi, and other microcontrollers

Technical Specifications:

Straight (unbent) resistance: ~25KΩ

Resistance tolerance: ±30%

Bend resistance range: Up to ~60KΩ

Rated power: 0.5W (peak: 1W)

Size: 73.66mm × 6.35mm

Interface type: 2-pin metal header

Important Usage Notes:

✅ Bend Direction: The side with the text should face inward during bending

❌ Avoid bending the terminal pins (non-sensing area) to prevent damage

Ideal For:

Wearable technology (e.g., energy gloves, motion control suits)

Robotics and gesture detection

DIY electronics and STEM projects

Smart textiles and biomechanics applications
