The Internet of Things (IoT) would greatly improve daily living if smart sensors could be embedded in commonplace items and places. However, this would require trillions of these tiny devices. Professor Vincenzo Pecunia of Simon Fraser University thinks that new alternative semiconductors that are printable, inexpensive, and environmentally benign could pave the way for a more affordable and sustainable IoT. Pecunia has identified major priorities and prospective possibilities for printable electronics to enable self-powered, environmentally friendly smart sensors. She is in charge of an international team of top professionals in several fields of printable electronics. His forward-looking insights are outlined
