What does a flex sensor detect?

A flex sensor or bend sensor is a sensor that measures the amount of deflection or bending. Usually, the sensor is stuck to the surface, and resistance of sensor element is varied by bending the surface.

What uses a flex sensor?

4. Other Applications – Flex sensors are common in different technological products, such as automotive and industrial controls, computer peripherals, joysticks, and measuring devices. These are also present in fitness products, musical instruments, and assistive technology systems of modern vehicles.

What is an example of a flex sensor?

This flex sensor is a variable resistor like no other. The resistance of the flex sensor increases as the body of the component bends. Sensors like these were used in the Nintendo Power Glove. They can also be used as door sensors, robot whisker sensors, or a primary component in creating sentient stuffed animals.

How do you test a flex sensor?

The easiest way to read the flex sensor is to connect it with a fixed value resistor (usually 47kΩ) to create a voltage divider. To do this you connect one end of the sensor to Power and the other to a pull-down resistor.

How sensitive is a Flex Sensor?

Flex sensor. The Flex Sensor is a unique component that changes resistance when bent. An unflexed sensor has a nominal resistance of 10,000 ohms (10 K). When the sensor is bent at 90 degress its resistance will range between 30-40 K ohms.

Is Flex Sensor analog or digital?

Here’s how it works: The flex sensor’s output is connected with Arduino’s analog pin input. An LED is connected to Arduino Uno’s pulse-width modulation (PWM) pin # 3. The sensor is powered with Arduino’s 5V regulator output.

Is flex sensor analog or digital?

How far can a flex sensor Bend?

An unflexed sensor has a nominal resistance of 10,000 ohms (10 K). As the flex sensor is bent the resistance gradually increases. When the sensor is bent at 90 degress its resistance will range between 30-40 K ohms. The sensor measures 1/4 inch wide, 4 1/2 inches long and is only .

What is the bend resistance of spectra symbol flex sensor?

Spectra Symbol Flex Sensor has a simple construction with a low profile and is able to bend and flex physically with a motion device. Spectra Symbol Flex Sensor has a bend resistance range of 45KΩ to 125KΩ (depending on bend radius). The sensor features 45KΩ to 125KΩ (depending on bend radius) bend resistance range.

Why choose spectra symbol?

A happy accident in the 1980s changed the trajectory of Spectra Symbol from screen-printing T-shirts to printing the most revolutionary membrane sensors on the market. Now a recognized leader in the linear position sensor industry, Spectra continues to break new ground by developing innovative sensors to respond to our clients’ unique needs.

What are the active lengths of the flex sensors?

Made with the finest materials, this product is essential in any manufacturing and robotics facility. Spectra Symbol flex sensors are available in the following active lengths: 2.18 inches and 3.75 inches.

What type of substrate is used for the flex sensor?

Spectra Symbol’s flex sensor is a 4.5″ bendable substrate that gives higher resistance readings as it flexes to a tighter radius. This 10 KΩ sensor has low power requirements for its output feedback. The resistance can increase up to 5-times the base or flat state reading.
