    摘要: Thermal sensing devices can include two subsets of thermal sensors connected in a bridge by circuitry on the same support layer or surface with the sensors. Each thermal sensor can be formed in a patterned layer of semiconductor material, and the bridge circuitry can include leads formed in a patterned layer of conductive material, over or under the semiconductor layer. In one implementation, the bridge circuitry includes conductive portions that extend across and electrically contact the lower surface of each sensor's semiconductor slab. The bridge circuitry can also include pads that can be electrically contacted, such as by pogo pins. The device's reaction surface can be spaced apart from or over the thermal sensors. The device's components can be shaped and positioned so that the bridge's offset voltage is below the sensitivity level required for an application, such as by left-right symmetry about an axis.

    摘要: Thermal sensors for calorimetry can include vanadium oxide, heavily p-doped amorphous silicon, or other materials with high temperature coefficients of resistivity. Such thermal sensors can have low noise equivalent temperature difference (NETD). For example, a thermal sensor with NETD no greater than 100 μK over a bandwidth range of approximately 3 Hz or more can include a thermistor including vanadium oxide sputtered at room temperature under conditions that yield primarily V2O5; more specifically, the NETD can be no greater than 35 μK, or even 10 μK over a bandwidth range of approximately 3 Hz or more. If a low noise thermal sensor has NETD no greater than 50 μK over such a bandwidth range, a low noise output circuitry connected to its thermistor can provide an electrical output signal that includes information about input thermal signal peaks with amplitude of approximately 100 μK.

    摘要: In thermal sensing devices, such as for calorimetry, a support layer or central layer can have a thermometer element or other thermal sensor on one side and a thermally conductive structure or component on the other. The thermally conductive structure can conduct temperature or other thermal input signals laterally across the support layer or central layer. The temperature or signals can then be provided to the thermometer element, such as by thermal contact through the support layer. An electrically conducting, thermally isolating anti-coupling layer, such as of gold or chromium, can reduce capacitive coupling between the thermally conductive structure and the thermometer element or other thermal sensor.

    摘要: Improved electric field (steered-electron electric-field, or SEEF) sensors and methods of manufacturing the same are provided. The SEEF sensors described herein may have increased sensitivity to low-frequency electric fields while being smaller than previously known sensors, and may allow for low-power electric field detection. The invention described herein allows for sensitive, long-term electric field monitoring for applications ranging from personnel detection to underground facility monitoring, as well as extraordinarily small vector sensing (full Poynting vector) for compact direction-finding of emitters of interest. Exemplary electric field sensors may accurately sense, measure, characterize and/or transmit electric field data over a wide frequency range. Importantly, such sensing, measuring, and/or characterizing do not require any physical or resistive contact between the sensor and a source of an electric field.
