In this work micro temperature and humidity sensors are fabricated to measure the junction temperature and humidity of light emitting diodes (LED). The junction temperature is frequently measured using thermal resistance measurement technology. The weakness of this method is that the timing of data capture is not regulated by any standard. This investigation develops a device that can stably an...

The ability of a non-propagating transport device (test device) to maintain the viability of clinically relevant bacteria was compared with a similar commercial device (predicate device) to establish performance equivalence. Test bacteria, namely Chlamydia trachomatis, Chlamydia pneumoniae, Mycoplasma hominis, Mycoplasma pneumoniae and Ureaplasma urealyticum, were inoculated into the test [Puri...

A custom designed microelectromechanical systems (MEMS) micro-hotplate, capable of operating at high temperatures (up to 700 °C), was used to thermo-optically characterize fluorescent temperature-sensitive nanosensors. The nanosensors, 550 nm in diameter, are composed of temperature-sensitive rhodamine B (RhB) fluorophore which was conjugated to an inert silica sol-gel matrix. Temperature-sensi...

This work examines the quality factors (Q factors) of resonance associated with the axial and transverse vibrations of single-wall carbon nanotube (SWCNT) resonators through the use of molecular dynamics (MD) simulation. Specifically, the work investigates the effect of device length, diameter, and chirality, as well as temperature, on the resonant frequency and quality factor of these devices ...

In this article, the design and modeling details of room-temperature analog-to-digital converter (ADC) based on silicon quantum-dot (QD) single-electron transistors (SETs) is presented. In contrast to the conventional metal quantum dots, the use of silicon QDs in the scales of few nano-meters enhances the device operation and makes stable the Coulomb blockade and Coulomb oscillation regimes at ...

OBJECTIVE To create a mechanical model that could be regulated to simulate the conditioning of inspired and expired air with the same normal values of temperature, pressure, and relative humidity as those of the respiratory system of a healthy young man on mechanical ventilation. METHODS Using several types of materials, a mechanical device was built and regulated using normal values of vital...
