摘要： A catalyst having a porous support having at least one of thermally or electrically conductive particles bonded by a polymer, and enzymes embedded into pores of the porous support. A process of manufacturing an enzyme-embedded porous support includes forming solution of monomers, enzymes, a solvent, and at least one of electrically and thermally conductive particles, polymerizing the monomers by adding initiators to the solution, and evaporating the solvent to produce an enzyme-embedded porous support. A process of manufacturing an enzyme embedded porous support, includes mixing enzymes, at least one of electrically conductive or thermally conductive particles, and a polymer in a solvent, and evaporating the solvent.

摘要： A colorimetric sensor has a first material deposited on a surface, and sensing particles on a surface of the first material, wherein the sensing particles comprise sensing species dispersed into porous host structures, such that at least a portion of the sensing particles is exposed to an ambient environment, wherein the first material attaches the sensing particles to surface. A method of forming a colorimetric sensor including depositing a first material onto a substrate, providing porous sensing particles, wherein the sensing particles comprise sensing species dispersed into a porous host structure, and embedding the porous sensing particles onto a surface of the deposited first material, wherein the first material attaches the sensing particles to the substrate such that at least a portion of the sensing particles is exposed to an ambient environment.

摘要： An apparatus includes a structure comprising a predetermined breakable region and a mechanical actuator disposed at or proximate the predetermined breakable region. The mechanical actuator comprises an impact member coupled to a spring arrangement, and a restraint member operably coupled to the spring arrangement. A trigger source is operably coupled to an electrical power source. The trigger source, in response to receiving current from the electrical power source, is configured to release or break the restraint member so as to allow the spring arrangement to forcibly move the impact member into contact with, and break, the predetermined breakable region.

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.

摘要： A sensor has a transparent polymer aerogel, and sensing materials dispersed into the transparent, polymer aerogel, where the sensing materials change color in response to environmental conditions. A method of forming a sensor includes providing a substrate, forming a polymer aerogel layer on the substrate, and infusing the polymer aerogel layer with sensing molecules.
