RESONANCE BASED MICROMECHANICAL CANTILEVER FOR GAS SENSINGIJNSA Journal
Our world is facing some drastic changes in the climatic conditions due to the heating effect caused by various greenhouse gases. The most harmful gas among them is Carbon dioxide and is increasing at an uncontrolled rate.
This paper aims in finding out the quantity of the major polluting gas carbon dioxide. The gravimetric sensor works by adsorbing the CO2 molecules on ZnO sensing layer, which alters the overall mass of the sensor. The mechanical structure is a cantilever, having its own resonant frequency. To selectively adsorb CO2 molecules from the mixture of gaseous molecules, ZnO at a specific temperature is used. As the gas molecules are adsorbed the mass increases and hence there is a change in resonant frequency. This change in frequency gives the measure of the quantity of CO2 molecules present in that environment. The major expected advantage of this technique would be the repeatability of the sensor that is used. This Quantitative analysis of CO2 would be helpful for mankind by alerting them about the environment in which they work, by proper conditioning and networking.
This discussion of the operating principles of capacitive, resisitive, and thermal conductivity humidity sensors also addresses their advantages, disadvantages, and applications.

Functionalizing these nanowire sensors allows their use for biochemistry, gases, and pH levels by detecting changes in electrical conductance when species adsorb to the nanowires.

Understanding User Needs and Satisfying ThemAggregage
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs
A wireless, remote query magnetoelastic co2 sensor
1. A wireless, remote query magnetoelastic CO2 sensor | ISweek - Industry sourcing
This paper presents a wireless, passive, remote query CO2 sensor comprising a ribbon-
like magnetoelastic thick-film coated with a mass-changing CO2 responsive polymer
synthesized from acrylamide and isooctylacrylate.
In response to a magnetic field impulse, the magnetostrictive magnetoelastic sensor
vibrates at a characteristic resonant frequency that is inversely dependent upon the mass
of the attached CO2 responsive polymer. The mechanical vibrations of the
magnetostrictive sensor launch magnetic flux, which can be detected remotely using a
pickup coil.
By monitoring the resonant frequency of the passive sensor, the atmospheric CO2
concentration can be determined without the need for physical connections to the sensor
or specific alignment requirements.
The effect of humidity and the CO2 responsive copolymer composition on the
measurement sensitivity are reported. Greatest sensitivity is achieved with a polymer
comprising a 1:1 mole ratio of acrylamide to isooctyl acrylate. A 0.7% change in
atmospheric CO2 concentration can be detected for a 20 microns thick polymer coated
sensor.
