Hi guys,
    I've a weird one here that I've been racking by brain with. I need to
generate a vibration that is detectable by a human as a small tickle -
equivalent to a spider/insect crawling on your foot. My problem is that I've
only got 3V to work with from a coin cell(or 2) i.e. zilch current!. Also it
will be driven by a PIC running from the same battery so low power
consumption is of utmost importance.

I've been playing with piezo elements - I'm waiting on some housed elements
to be delivered to see if the resonant soundbox helps.

The proposed application area would prohibit the use of a cellphone
vibrating battery so that is discounted.

I just thought I'd throw this one out for comments.

Best regards, John
