2.2 Flex Sensor

A 2.2 Flex Sensor is typically a type of sensor used to measure the amount of bend or flex in a material. These sensors are often used in various applications, such as robotics, wearable devices, and human-computer interaction systems, to detect changes in position or the bending of surfaces.

Here’s a breakdown of how a 2.2 Flex Sensor works:

1. Basic Functionality:

• A flex sensor works by changing its resistance as it bends. The sensor contains a conductive material that alters its electrical resistance when deformed.
• When the sensor is flat, its resistance is at a baseline. As the sensor bends, the resistance increases, and this change can be measured with a microcontroller or other electronics.

2. Specifications:

• The "2.2" could refer to the physical length of the sensor (in inches), indicating that it's 2.2 inches long. The length of the sensor influences its flexibility and sensitivity to bending.
• The resistance change typically ranges from several hundred ohms to several thousand ohms, depending on the degree of flex.

3. Applications:

• Wearable Technology: Monitoring finger movement in prosthetics or gloves for interaction with virtual reality (VR) or augmented reality (AR).
• Robotics: Used to detect joint angles and provide feedback on movement.
• Medical Devices: Can be integrated into braces or other assistive technologies to measure joint movement.
• Gesture Control: In human-computer interaction (HCI), flex sensors can detect hand gestures for control.

4. Working Principle:

• The flex sensor usually has a resistive layer that is constructed in a way that it flexes when bent. The sensor's bending changes the conductive properties, which are then measured by an electronic circuit to determine the degree of flex.

5. Integration:

• These sensors are often integrated into circuits alongside analog-to-digital converters (ADC) to translate the resistance change into a usable value.
• In many cases, a voltage divider circuit is used to calculate the resistance change, with the flex sensor as part of the divider.
