“…On the other hand, in order to observe the influence of the addition of Al 2 O 3 on the compactness of ceramics, the density of each component is measured to be 7.852, 6.935, and 6.930 g/cm 3 for x = 0, 0.1, and 0.2, respectively. The reason for the gradual decrease in density is attributed to the low density (∼3.5 g/cm 3 ) of Al 2 O 3 .…”

High pyroelectric performance around human body temperature is essential for ultra‐sensitive infrared detectors of medical systems. Herein, toward human health monitoring, composite ceramics (1‐x)Pb0.99Nb0.02[(Zr0.57Sn0.43)0.94Ti0.06]0.98O3/xAl2O3 (x = 0, 0.1, and 0.2) were designed. A metastable ferroelectric (FE) phase was induced in the anti‐FE matrix by the Al2O3 component‐induced internal stress, and in turn FE‐anti‐FE phase boundary was constructed. The ceramics at x = 0.2 exhibit high pyroelectric coefficient with p = 10.9 × 10−4 C·m−2·K−1 and figures of merit with current responsivity Fi = 6.23 × 10−10 m·V−1, voltage responsivity Fv = 12.71 × 10−2 m2·C−1, and detectivity Fd = 7.03 × 10−5 Pa−1/2 around human body temperature. Moreover, the enhanced pyroelectric coefficients exist in a broad operation temperature range with a large full width at half maximums of 18.5°C and peak value of 29.2 × 10−4 C·m−2·K−1 at 48.2°C. The designed composite ceramic is a promising candidate for infrared thermal imaging technology of noncontact human health monitoring system.

“…[12,13] The lack of effective single-phase materials has led to recent efforts focused on piezoelectric-electrochromic composites to meet this design need for various sensors and devices. [14][15][16] Recently, it became possible to grow large (centimeter size) single crystals [17] of the relaxor materials Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PMN-PT) and Pb(Zn 1/3 Nb 2/3 )O 3 -PbTiO 3 which outperform conventional ceramic PZT-based materials due to extremely high piezoelectric (d 33 ≈ 2000 pm V −1 ) and coupling (k 3 ≈ 0.9) coefficients. [18][19][20][21][22][23] The success of these materials is due in part to domain engineering, a process used to modify the electric or mechanical response of a material through the manipulation of its domain configuration by cutting the crystals along certain crystallographic planes and then poling them with electric field along a particular crystallographic direction.…”

Electrical switching of ferroelectric domains and subsequent domain wall motion promotes strong piezoelectric activity, however, light scatters at refractive index discontinuities such as those found at domain wall boundaries. Thus, simultaneously achieving large piezoelectric effect and high optical transmissivity is generally deemed infeasible. Here, it is demonstrated that the ferroelectric domains in perovskite Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 domain‐engineered crystals can be manipulated by electrical field and mechanical stress to reversibly and repeatably, with small hysteresis, transform the opaque polydomain structure into a highly transparent monodomain state. This control of optical properties can be achieved at very low electric fields (less than 1.5 kV cm−1) and is accompanied by a large (>10 000 pm V−1) piezoelectric coefficient that is superior to linear state‐of‐the‐art materials by a factor of three or more. The coexistence of tunable optical transmissivity and high piezoelectricity paves the way for a new class of photonic devices.

“…To date, electrochromic (EC), photochromic (PC), and thermochromic (TC) materials or composites have application potential in smart windows. [ 1–4 ] Unfortunately, EC materials consist of multilayer transparent films with diverse compositions and complicated fabricating processes are indispensable. And modulations of optical transmittance in PC materials adhere to alternate stimulation of illumination and temperature rise that could be inconvenient in practice, whereas TC materials are enslaved to variations of ambient temperature that can hardly be precisely controlled like electric field.…”

Smart windows with adjustable transmittance via physical stimuli are eagerly desired for sorts of energy‐saving lighting systems. However, reciprocal trade‐off relationship such as high transparency and coloration/discoloration ability exists in smart windows, not conducive to optical‐electrical coupling and leap in performance. Substituting for common composites utilized in smart windows, here, single transparent ceramic‐based smart windows are reported through composition design and defect management strategies to regulate the optoelectronic performances and break off the contradictions between optical transmittance, photo‐thermochromism and electrical conductivity. By first principles calculations and precisely tuning Er3+, Ba2+, Sr2+ concentrations in non‐stoichiometric Er‐doped (K0.5Na0.5)NbO3‐(Ba, Sr)TiO3, the fabricated ceramics exhibit brilliant transparency and multi‐mode dramatical and reversible modulations of pellucidity, photoluminescence intensity, along with conductivity (over fivefold variation), enabling prominent optoelectronic information storage and modulating capacity in vivid potential applications, such as easy‐readout/erasable optical memorizers, photo‐memristors and anti‐counterfeiting displays.
