摘要： A system of sensor nodes is combined with an RF hub that transmits RF power to the sensors and receives data therefrom. The sensor nodes contain: one or more sensors for measuring indoor conditions, an antenna, an energy storage element, and electronics for powering the system via harvesting RF energy, reading sensor data, and communicating sensor data. The sensors, antenna, and other components on the nodes can be fabricated conventionally, or via printing. They may be fabricated as “flexible hybrid electronics”, in which conventional components are bonded onto flexible substrates. The RF hub consists of one or more antennas capable of transmitting RF power electronics for steering the center of radiation of the RF power in at least one direction or in more than one direction electronics for receiving a demodulating RF data signal. The RF hub may be powered directly from the building.

摘要： Disclosed herein are methods of producing metal nanoparticle-decorated carbon nanotubes. The methods include forming a reaction mixture by combining a first solution with a second solution, wherein the first solution comprises polymer-coated metal nanoparticles comprising metallic nanoparticles coated with a polymer, and wherein the second solution comprises carbon nanotubes. The methods also include heating the reaction mixture to a temperature greater than a glass transition temperature of the polymer for a time sufficient to cause the polymer-coated metal nanoparticles to bind to the carbon nanotubes forming the metal nanoparticle-decorated carbon nanotubes.

摘要： A gas monitor apparatus includes a sorbent material that adsorbs a target gas based on a concentration of the target gas in a monitored environment and a reference material that does not respond to the target gas. The gas monitor also includes a first thermistor disposed within the sorbent material and a second thermistor disposed within the reference material, the first thermistor to provide a first indication of a first temperature of the sorbent material and the second thermistor to provide a second indication of a second temperature of the reference material. A processing device determines a concentration of the target gas based at least in part on a differential measurement between the first temperature and the second temperature.
