A flex sensor is a type of electronic component that changes its resistance when it’s bent or flexed. It’s typically made of a flexible substrate with conductive material applied on it. When the sensor bends, the distance between the conductive elements changes, altering the resistance of the sensor. This change in resistance can be measured and used to determine the degree of bending or flexing.
Flex sensors are commonly used in various applications, including robotics, wearable devices, medical equipment, and gaming controllers. They provide a simple and intuitive way to capture the bending or flexing of objects, allowing for more natural interactions between humans and machines.
These sensors can come in different shapes, sizes, and resistance ranges, making them versatile for different use cases. Some sensors provide analog output, where the resistance change corresponds directly to the degree of bending. Others can be integrated with microcontrollers to provide digital output or even be part of more complex sensing systems.
Overall, flex sensors play a crucial role in enabling devices to sense and respond to human movement or the deformation of objects in a user-friendly manner.
