The fabrication of sensors is another important opportunity for printed and flexible electronics. A variety of stimuli can be detecting using such circuits, including temperature, pressure, radiation, and chemical identity. An integrated temperature and pressure sensor array has been utilized as an artificial skin. Actuators have also been fabricated. For instance, an electronic Braille actuator was fabricated and provided sufficient stimuli to be read by a blind person. These principles have been used to produce a variety of different types of devices, including tamper detecting packaging, data logging pill dispensers, chemical sensors, electronic noses and tongues, photodiodes, and light scanners, and a recent DARPA program is aiming to develop sensing tapes integrated with textiles for military applications. |
