Implantable medical devices are wished to be recharged via contactless power transfer technologies without interventional operations. Superior subcutaneous supply by visible light or electromagnetic wave, second near-infrared (NIR-II) is predicted possess 60 times transmission but hard utilized. Here we report a photo-thermal-electric converter the combination of photothermal conversion and thermoelectric conversion. It able generate an output as high 195 mW under coverage excised tissues,...
Abstract In nature, the ability to regulate and transmit color signals is fundamental adaptive survival of many organisms. A key aspect this adaptability autonomous detection chromatic changes in color‐displaying structures, facilitating precise matching with environmental stimuli. However, conventional mechanochromic materials rely on a single mechanical force feedback channel, lacking continuously monitor their state real‐time. work, novel approach presented that integrates ZnS@SiO 2...
Despite possessing higher tissue transmittance and maximum permissible exposure power density for skin relative to other electromagnetic waves, second near-infrared light (1000-1350 nm) is scarcely applicable subcutaneous photoelectric conversion, owing the companion photothermal effect. Here, thermal management conceived utmostly utilize effect of a photovoltaic cell, which not only improves conversion efficiency but also eliminates hyperthermia. In vivo, output can be than 500 mW with...
The full color greenish-white-emitting phosphors Eu 2+ -doped Sr 3 Bi(PO 4 ) have been successfully synthesized by the conventional solid-state reaction, and its photoluminescence properties investigated for first time. emission spectra of ∶Eu exhibit a combining blue, green, red emissions, which are originated from 5d→4f transition . excitation reveal broad strong bands 300 to 400 nm, match well with readily available emissions near-ultraviolet light-emitting diode (LED) chips. correlated...
Tunable Diode Laser Absorption Spectroscopy (TDLAS) is a non-intrusive method of measurement, which has lots advantages, such as real-time, fast response, high sensitivity, easy operation, harsh condition applicability and so on. In this paper, the 7173.781201 7199.37761 cm<sup>-1</sup> line pair water vapor were selected for temperature measurement flat flame burner. order to observe non-uniform distribution, Fourier-Hankel transform in inverse Abel was used convert integrated temperature,...
Wavelength modulation - direct absorption spectroscopy (WM-DAS) is proposed by extracting the characteristic spectrum. This method improves accuracy of absorbance profile measurement one order magnitude and verified experiments.
