What sensor can I use to determine rotation?

Question

Guys is there any sensor online that is small to fit between two finger joints and calculate how much degrees its turned, i am lanning to make a glove that has ability to see at what position fingers are turned to.

I thaught of potentiometer but its too large to fit between finger joints, also what i men to say is that i am making a glove like thing where a sensor is needed which can be attached at finger joints to see ho much is it turned

accelorometer, inclinometer, gyroscopes can all do this. depending on how you do joint articulation you may be able to use a magnomometer, or encoder. then you can also make your own sensors with that packing foam, and conductive thread. you could read the capacitance changes, or... well there is a lot of things you could do, without further detail on constriction, it s hard to say. is it joint position in 3d space?

I have one of these Essential Reality P5 gloves. This video from LGR provides some insight into what kind of performance you might achieve....

 Perhaps take a look at some of the small SMD ones ? 
 Bourns do some thin rotary position sensors: https://www.bourns.com/data/global/pdfs/3382.pdf

There are always multiple ways to approach a solution. Give flex sensor a test and let us know result. Which flex sensor are you considering ? 
 I was thinking a micro absolute encoder , but there would need to be an rigid exo-skeketon. The sensor accuracy wearing gloves or other attachment would have inherent slippage. 
 Solid state sensors like magnetometers, imu, gyros involve alot of calibration, calculation, and proper filtering, which why I only use them when they are the best solution.

I recall that there are some sensor glove based student projects listed here:
