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