The LPG gas sensing response of polyethylene oxide ( PEO )- Cu ( Cu = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 and 1.0 wt. %) composite thick films prepared on alumina substrates by using novel screen printing technique are reported in present paper. The gas sensing responses of films were tested at 1000 ppm of LPG by using home-built static gas sensing system [between room temperature - 50 °C]. A very high value of SF = 1400 was obtained at an optimum temperature of 47 °C for a film with Cu = 0.7 wt.%. Further, better LPG sensing response, SF = 700 was obtained at low operating temperature = 36 °C for a film with Cu = 0.2 wt. %. The LPG sensing responses of the films were found to be strongly influenced by concentration level of Cu additive.


The light dependent resistor (LDR) are prepared using bulk CdS material and using conventional thick film technique. But bulk CdS and this conventional thick film technique gives lower inter-electrode spacing resulting poor response. In the present work, the CdS nanostructure was synthesized using hydrothermal reaction technique and with the help of screen printing technique, the CdS pattern having lower inter-electrode spacing resulting larger length of the CdS was prepared. As the inter electrode spacing increases the photocurrent also increases resulting enhancement of the sensor response. The work reported in the present paper provides the photo-sensor having higher sensitivity
