Stretchable Electronics to go on Electroactive Polymers

Micromuscle AB in Sweden is one of several companies developing electroactive polymers. Their products will be used as muscles, locks (for example on packages of hazardous chemicals) and even communication with the partially sighted and others by change of texture, perhaps using changeable Braille. For example, the package could sense that it has been left out for too long and the Braille could change from giving an expiry date to saying EXPIRED DO NOT USE. Micromuscle pumps could be an environmental alternative to aerosols, if powerful enough printed batteries become available.
