摘要： Apparatus for the detection of a vapor of a selected chemical substance includes a sensor whose impedance changes upon exposure to such a vapor. The sensor comprises a polymer whose physical structure is altered by the vapor, e.g., through expansion or disintegration, and electrically conductive elements that are interspersed with or separated by the polymer. The interspersed elements may consist of a fine powder of carbon or of a metal in a matrix of silicone or other vapor-sensitive polymer. The electrical contacts between the powder particles are weakened when the polymer swells or disintegrates, which results in increased resistance. Alternatively, the capacitance between two conductive layers separated by a polymer layer decreases, and hence the impedance increases, when the polymer swells upon exposure to the vapor. In yet another embodiment, the polymer exerts a stress on a piezoresistive element and the stress is increased when the polymer swells, which causes a further increase in resistance. The changes are measured by an impedance-measuring circuit, such as a Wheatstone bridge.

摘要： A relatively inexpensive modular component that can be substituted for, or used in conjunction with, an existing smoke detector in a commercially available residential fire-detection alarm comprises: (A) an amperometric sensor for carbon monoxide, in which the reference and counter electrodes are combined either internally into a single auxiliary electrode or externally by electrical shorting; and (b) a simple current-to-voltage converter circuit that converts the current signals from the sensing electrode into amplified voltage signals. The converter circuit is powered by the same battery (usually a 9-volt dry cell) and is connected to the same alarm-triggering circuit that are used in existing residential fire alarms. The sensor-and-converter module is designed to fit into a commercially available smoke-detector-type fire alarm unit. The electrical output of the module is designed to be compatible with the electrical input requirements of the commercial detection circuitry. An alarm fitted with this module provides early warning of hazardous conditions, such as a smoldering fire, a leaky furnace, or an otherwise heavily polluted atmosphere.

摘要： A potentiostat for an amperometric sensor uses a voltage-controlled current source (VCCS), which may be either unidirectional or, preferably, bidirectional. An error amplifier compares the potential of the sensor's reference or counter electrode, relative to ground potential, to a set-point potential. The error voltage serves as an input to the VCCS. The output of the VCCS--a current proportional to the error voltage--is supplied to the sensor's auxiliary electrode. In a steady state, the error voltage is just large enough to supply current that is equal to the current through the sensor's working and auxiliary (or counter) electrodes. The error voltage can either serve directly as an output voltage or it can be amplified without introducing a feed-back loop disturbance. The VCCS permits direct grounding of the sensor's working electrode and operation of the error amplifier at a low or moderate gain, so as to increase the circuit's frequency response and reduce the probability of oscillation. Also, in conjunction with an adjustable low-pass filter, the VCCS permits optimization of the system's frequency response so as to yield improved stability.

摘要： A portable instrument for use in the field in detecting, identifying, quantifying, and monitoring gas, liquid or solid materials is disclosed. The instrument may analyze either liquids or gases depending upon the type of sensor array therein. The instrument also includes means for changing a gas, liquid or solid to a fluid material. The instrument further includes an array or small sensors which, upon exposure to the unknown material, form a pattern of electrical responses, a source of previously formed response patterns characteristic of various materials, and microprocessor means for comparing the sensor-formed response pattern with one or more previously-formed response patterns to thereby identify the material on a display. The number of responses may be increased by changing the operating voltage, temperature or other condition associated with one or more sensors to provide a plurality of responses from each of one or more of the sensors. The instrument is capable of identifying a large number of liquid and solid materials.
