2019, Sensors and Actuators, A: PhysicalCitation Excerpt :Two main categories of thermal detectors exist. The first one concerns uncooled thermal detectors, or microbolometers, which operate at room temperature using several temperature-sensing principles: resistive thermometers based on the change in the electrical resistance [1], diode- [2] or transistor-type [3] bolometers which exhibit a variation in their current-voltage response, thermocouple-based thermometers [1] which generate an electrical potential difference, pyroelectric sensors [4] which use an electric polarization variation of their sensitive material and require a mechanical shutter, MEMS (Micro Electrical Mechanical Systems) detectors [5], which are based, for example, on the change in the resonant frequency of their structures. The second category concerns cooled thermal detectors that have very high detection performances but operate at cryogenic temperatures.
Investigation of microstructure and mechanical properties of polyvinylidene fluoride/carbon nanotube composites after electric field polarization: A molecular dynamics study
2018, Computational Materials ScienceCitation Excerpt :However, under a high electric field, PVDF in the α-phase is transformed to the polar β-phase, leading to the dipole moments aligning neatly in the electrical field direction. This β-phase PVDF polymorph has been widely applied to potential energy conversion applications [9] due to its excellent piezoelectric [10], ferroelectric [11], and pyroelectric [12] properties. Electrospinning (ES) is a nanofiber production method which draws the polar polymer threads to nanofibers from polymer solutions under electric fields.

2017, Sensors and Actuators, A: PhysicalCitation Excerpt :In other words, the pyroelectric effect is due to the dependence of the spontaneous polarization Ps, the dipole moment per unit volume of the material, on the temperature. Historically, the most important applications of the pyroelectric effect have been related to the possibility to measure the power generated by a radiation source, such as pyrometry, infrared imaging, radiometry [1–4]. However, there are other applications that are attracting great interest, including lithography [5,6], electrohydrodynamic effect based devices [7], electron emission devices [8,9], ion source spectrometry [10,11], alignment of nano-particles under electrode-free approaches [12], nano droplet drawing [13,14], self-trapping of optical beam in a photorefractive medium [15].
