Flexible logic: These printed transistors will be packaged with printed memory, sensor, and battery components for a cheap commercial temperature-monitoring system.
At the higher end, systems that can record exact temperatures over long periods of time, and store this data for either display or retrieval, cost $15 to $25 or more, and are limited to high-value items or pallet-sized shipments.
Jennifer Ernst, a Thin Film Electronics vice president, says the mix of materials, substrates, and printing technologies is still in development. “To the best of my knowledge, it’s the first time a set of companies have announced a plan to put a fully integrated system together,” she says. If it all works out and the performance is reliable, “we can achieve cost targets that silicon systems just can’t touch,” she adds.
