Deflating an inflatable?

Last week I presented my paper on the vr-costume Inflatable at the Electronic Visualisation & Arts conference. And to my relief the live demo worked ok. I’m planning to develop the inflatable further in terms of aesthetic/materials and haptic effect. And also want to deflate it with compact wearable electronics with the controller. Anybody know the simplest mechanics of this ?
