This is correct, although the bend sensors aren't all that great. I've got the glove and the accuracy isn't very much, about the best you can expect is what they've got from the glove , ie 4 different bend positions. But if this is enough for your (...)

If you go look at the imagesco page the sensor is the Part number FLX-01 and they are priced at $10.00 each.
