Droplets are propelled down these tracks, overcoming contact angle hysteresis using energy supplied by mechanical vibration. The rough hydrophobic surfaces have been designed to maintain air traps beneath the droplet by stabilizing its Fakir state. Dimensions and spacing of... View full abstract»

  • Ramp calibration of temperature sensors

    Publication Year: 2011, Page(s):67 - 70

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (941 KB) | HTML iconHTML

    This paper describes a new approach to the calibration of temperature sensors. The traditional approach, in which the output of a device-under-test (DUT) and that of a reference sensor are compared at a few temperatures, is time consuming and, therefore, significantly increases production costs. The proposed method, in which a temperature ramp is applied to the DUT, is much faster and therefore lo... View full abstract»
