simple effective angular position sensor for robotic finger

[Ehsan Zakipour]

what is the best yet simple to use angular position sensor ?
i am building a robotic hand and i want to implement this sensor at the joints of the fingers. i don't need a module, just an analogue output.
thank you.

Why not use a simple rotational potentiometer? If you need a higher accuracy, use a 10 turn linear potentiometer and a 1:10 gear coupling to the joint of the fingers.

Use a servo with current feedback. When the current rises, this is a maximum angle before obstruction.
