A flex sensor is invariably a flexible sensor that can essentially measure the resistance.
This sensor can detect flexing or bending in one direction. They were popularized by being used in the Nintendo PowerGlove as a gaming interface.
These sensors are easy to use, they are basically resistors that change value based on how much their flexed. If they’re unflexed, the resistance is about ~25KÎ©. When flexed all the way the resistance rises to ~100KÎ©. They’re pretty similar to FSRs so following this tutorial will get you started. You can use an analog input on a micro-controller (with a pullup resistor) or a digital input with the use of a 0.1uF capacitor for RC timing.
The bottom part of the sensor (where the pins are crimped on) is very delicate so make sure to have strain relief – such as clamping or gluing that part so as not to rip out the contacts!
