Sparkfun Flex Sensor 4.5 inch

This 11.4 cm flex sensor changes its resistance when bent. According to the manufacturer Spectra Symbol, such sensors were already used in the original Nintendo Power Glove. The connection pins have a pitch of 2.54 mm, so the sensor can be plugged directly into a breadboard.

Note: The usable area of the sensor may be bent. Bends outside it and close to the base must be avoided, otherwise the sensor can be destroyed. Bend away from the printed side, in the other direction the values are unreliable.

Recommended Accessories:

• Resistance Set 600 pcs. Assorted 1/4W 1% Accuracy

Features:

• Resistance increases with bending
• Evaluation via a voltage divider at an analog input, fixed resistor between about 10 kOhm and 100 kOhm, 47 kOhm in the SparkFun example
• 2 connection pins with 2.54 mm pitch

Application Examples:

• Detecting finger movements in data gloves
• Measuring the bending and deflection of components
