“…In 1834, Jean Charles Athanase Peltier, a French physicist, discovered the presence of heat at an electrified junction between two different conductors, namely, the Peltier effect. Since then, the aspects of the nonequilibrium thermodynamics of thermoelectric phenomena related to the Peltier effect in a semiconductor have received special attention [12]. One of the results archived when studying the Peltier effect in a quantum wire showed that a quasi-equilibrium situation is reached a defined local temperatures [13].…”

Photo-stimulated quantum thermo-magnetoelectric effects in doped two-dimensional semiconductor superlattices, including the photo-stimulated quantum Ettingshausen effect and the photostimulated quantum Peltier effect, have been theoretically studied by using the quantum kinetic equation method. In this work, we assume that the electron-confined acoustic phonon scattering is essential. Moreover, the presence of the laser radiation (LR) is also taken into account to determine the influence of confined phonons on the aforementioned effects. We have defined the analytical expressions for the kinetic tensors and the Ettingshausen and the Peltier coefficients, presented the numerically calculated the theoretical results for the GaAs:Si/GaAs:Be doped semiconductor superlattice and compared them with these for the case of an unconfined acoustic phonon. The results obtained indicated that the formulas for the kinetic tensors, the Ettingshausen coefficient (EC) and the Peltier coefficient (PC) contain the quantum number m specifying the confinement of a phonon and approach the results for an unconfined phonon as m goes to zero. We found that the kinetic tensors, the EC and the PC oscillate with changing magnetic field and that the confinement of a phonon causes a shift of the peaks in these oscillations to lower energy. The dependences of both EC and PC on the temperature were found to be nonlinear. Moreover, all the coefficients level off when the temperature was less than 4.5 K or greater than 5.5 K. The EC also depended on the doping concentration in a nonlinear way and reaches a positive constant value when the semiconductor superlattice was doped with a high concentration. Most of the numerical results showed that the magnitude of the tensors, the EC as well as the PC, within a confined acoustic phonon varie significantly in comparison with the unconfined phonon case. This means that the confinement of the phonon affects the thermo-magnetoelectric effect quantitatively and qualitatively. These results contribute to completing the theory of the thermo-magnetoelectric effects in the low-dimensional semiconductor systems.

“…The sensor comprises an actively controlled thermistor inside the mask along with a Thermoelectric Cooler (TEC) outside the mask.

Introduction There is a paucity of noninvasive respiratory monitors for patients outside of critical care settings. The Linshom respiratory monitoring device is a novel temperature‐based respiratory monitor that measures the respiratory rate as accurately as capnography. Objectives Determine whether the amplitude of the Linshom temperature profile was an accurate, surrogate and qualitative metric of the tidal volume (VT) that tracks VT in healthy volunteers. Methods Forty volunteers breathed room air spontaneously through a tight‐fitting continuous positive airway pressure mask with a Linshom device mounted in the mask. VT was measured contemporaneously using a standalone Maquet Servo‐i ICU ventilator. The amplitudes of the Linshom temperature profiles were paired with the contemporaneous VT measurements using least squares linear regression analysis and the coefficient of variation (R2) was determined. Results Forty volunteers completed the study. The data from 30 of the volunteers were analysed and are presented; data from 10 volunteers were not included due to protocol violations and/or technical issues unrelated to Linshom. The fluctuations in the amplitude of the Linshom temperature profiles mapped closely with the measured VT using least squares linear regression analyses yielding a mean R2 (95% CI) value of 0.87 (0.84‐0.90). Conclusion These results support the notion that the Linshom temperature profile is an accurate and reliable surrogate that tracks changes in VT in healthy volunteers. Further studies are warranted in patients in clinical settings to establish the effectiveness of this monitor.

The thermoelectric effect forms the basis of Peltier cooling that has attracted interest for solid-state refrigeration for more than a century. The dearth of materials level efficiency in converting between heat and electricity has limited widespread applications. With renewed focus on energy technologies in the past three decades, the thermoelectric effect has been intensely explored in new materials using state-of-the-art advances in materials fabrication, characterization techniques, and theory. This article aims to navigate the complex landscape of these studies to identify credible advances, pinpoint continuing problems, and lay out future prospects for both research and applications, with emphasis on electronics cooling.
