“…The rapid response and recovery observed for nanowire sensors are consistent with the expectation of improved properties associated with their high surface-to-volume ratio. Moreover, in contrast to the nanowires sensors explored here, thin film sensors show significant baseline drift to the point of sensor destruction after prolonged exposure to methanol at P/P 0 = 0.05 [17].…”

We measured the electronic properties and gas sensing response of nanowires containing segments of poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT/PSS) that were synthesized using anodic aluminum oxide (AAO) membranes. The nanowires have a "striped" structure of gold-PEDOT/PSS-gold and are typically 8 μm long (1 μm-6 μm-1 μm for each section, respectively) and 220 nm in diameter. Dielectrophoretic assembly was used to position single nanowires on pre-fabricated gold electrodes. A polymer conductivity of 11.5  0.7 S/cm and a contact resistance of 27.6  4 k were inferred from resistance measurements of nanowires of varying length and diameter. When used as gas sensors, the wires showed a resistance change of 10.5%, 9%, and 4% at the saturation vapor pressure of acetone, methanol and ethanol, respectively. Sensor response and recovery were rapid (seconds) with excellent reproducibility in time and across devices. "Striped" template-grown nanowires are thus intriguing candidates for use in electronic nose vapor sensing systems.Keywords: polymer nanowire vapor sensor dielectrophoretic assembly Biography of authorsYaping Dan received his bachelor and master degrees in microelectronics from Xi'an Jiaotong University in 1999 and Tsinghua University in 2002.

“…This spurred the development of inexpensive optical sensors capable of wireless communication [1,2]. Key requirements such as reproducibility, reliability, low power consumption, as well as sensitivity and selectivity are vital for scale-up and mass production of sensing devices which allow for more widespread deployments [3,4]. Availability of broadly applicable optical components like light emitting diodes (LEDs) or photodiodes opens the potential of sensors to be widely employed in platforms for wireless sensor network systems (WSN).…”

“…There are two possible body controlled type sensors according to the role of the adsorbed hydrogen molecules. In the first case, the adsorbents donate electrons to the p-type polymer matrix, increasing the resistance, whereas in the second case, the adsorbents cause the separation of the conduction path in the matrix, increasing the resistance [28,29].…”
