'People don't realize how sensitive we are to touch, although it is the first sense that fetuses develop in the womb,' says Paul Lemmens, a Philips senior scientist who will be presenting research done using the jacket at the IEEE-sponsored 2009 World Haptics Conference in Salt Lake City. The jacket contains 64 independently controlled actuators distributed across the arms and torso. The actuators are arrayed in 16 groups of four and linked along a serial bus; each group shares a microprocessor. The actuators draw so little current that the jacket could operate for an hour on its two AA batteries even if the system was continuously driving 20 of the motors simultaneously."
