Mimicking Touch

Leveraging the Biology of Tactile Sensation

by Bryon Moyer

Kids goof around with all kinds of things, not knowing what will occur. It’s how they learn how the world works, and it’s why they can learn novel electronic user interfaces so much more easily than adults (which we mistake as intuition). Well, in one such bout of goofing about on our apple orchard, I was monkeying with balloons over the opening of a bottle of apple cider.

You see, my dad had this thing where he’d poke a few needle holes in a balloon and then place it over the bottle opening. Fermentation would start, inflating the balloon, which opened the little holes and let the CO2 escape. When the process completed, the balloon deflated and the holes closed, blocking oxygen from reaching the inside – and preventing a continuation of the process that would otherwise lead to vinegar.*  Read More

What other ways do you know of to fake out our sense of touch for haptic use?

I wouldn't say it's "sloppy" in the conventional sense. Anything with a finite Q - including crystals - has some slop. As far as I know, the Q of high-quality MEMS actually competes well with crystal.

Sand 9 would point to some issues that crystal has…

Interesting example of how a sloppy Q factor can actually be useful.

For those situations where the low Q factor in MEMS isn't so useful (and there are many examples of that) - Crystal is still the answer.
