So what I have a need for is a piezo switch to trigger a camera flash, I've made the following:

Which is working well a tap with my finger nail fires the flash, but it isn't quite sensitive enough. I'm wondering if there's any suggestions as to increasing the sensitivity or preferably having variable sensitivity. A hard poke on the piezo generates about 30v.
