SMAs change shape when electrically heated and can apply more varied levels of body manipulation, says MIT. BT’s research lab near Ipswich, UK, is developing a novel USB plug-in: an accelerometer. The gadget will allow people with dexterity problems to control certain aspects of their software. For example,
