I would like to make glove with pressure sensor on each finger to detect a moment when piano player touches a key. What kind of sensor should I use? I tried use simple buttons, but it is very uncomfortable for player :)

  • \$\begingroup\$ Electronic keyboards still won't give you an event representing the very moment when the finger touches the key. A light-action keyboard provides a better approximation to that moment but there is still a delay, and it changes the whole feeling. Players also touch keys without playing a note, in anticipation of playing a note. \$\endgroup\$ – Kaz May 20 '13 at 4:32

The other answers are just as valid as mine. I'm just offering yet another option.

Use a piezo buzzer. Something like what is in this picture:

Piezo Buzzers

When the piezo element is struck/stressed/etc it will produce a voltage spike that can be detected. They are commonly used in drum machine pads, elevator buttons, etc. They are fairly cheap, so you could easily get one and hook it up to an o-scope and experiment.

  • \$\begingroup\$ Thank you. I also just have tried piezo, and it works well. Now I need to find very small piezo sensor. \$\endgroup\$ – Enthusiast May 19 '13 at 20:28

You could use resistive touch fabric, although I don't know how sensitive it is.

You could use capacitive keys.

You didn't provide very much information about your system, so I can't give very detailed information on how to use this in your setup.

Some microcontrollers can control capacitive keys with a peripheral. There are also controllers available for these keys.
