Flex (bend) sensor! This sensor can detect 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 ~10KΩ. When flexed all the way the resistance rises to ~20KΩ. They’re pretty similar to FSRs so following this tutorial will get you started. You can use an analog input on a microcontroller (with a pullup resistor) or a digital input with the use of a 0.1uF capacitor for RC timing. Flex (bend) sensor, in the Adafruit store.
