A wearable smart sensing system is capable of continuously monitoring biometric information such as respiration, pulse, and body temperature while attached to an arbitrary surface on the user's body to be utilized freely during activities. Research conducted on new materials, fabrication processes, structure of electrodes, and wireless communication technologies has made constant progress in the development of smart sensing systems that use entirely wearable forms of devices to go beyond conventional devices that are based on intrinsically rigid components, such as silicon. Among various platforms that can be used in the development of smart sensing systems, optoelectronics provides innovative sensing functions (e.g., human–machine interfaces and phototherapy) that can be transferred from traditional healthcare to smart healthcare, such as point of care. Optoelectronics are light‐mediated displays that allow a light source to be controlled and a large light spectrum to be detected. Recently, this platform that uses smart and wearable optoelectronic sensing systems has become increasingly advanced to better help human beings treat their diseases through self‐healthcare. Herein, recent advanced technologies in materials, structures, and wireless platforms for smart sensors using wearable optoelectronics are reviewed.

“…The universal generation of these LiOH and Li 2 CO 3 products, so‐called residual lithium, in high‐nickel lithium layered oxides is considered one of the immediate obstacles hindering their commercialization . One critical effect of these residues is an increase of the pH in the electrode slurry during mass‐scale electrode fabrication, which induces the crosslinking of polyvinylidene fluoride (PVdF) via a dehydrofluorination reaction and causes slurry gelation . It significantly complicates handling and storage of the slurry, making the electrode casting process uncontrollable on mass production lines.…”

The rampant generation of lithium hydroxidea nd carbonate impurities,commonly knownasresidual lithium, is apractical obstacle to the mass-scale synthesis and handling of high-nickel (> 90 %) layered oxides and their use as highenergy-density cathodes for lithium-ion batteries.H erein, we suggest as imple in situ method to control the residual lithium chemistry of ah igh-nickel lithium layered oxide,L i-(Ni 0.91 Co 0.06 Mn 0.03)O 2 (NCM9163), with minimal side effects. Based on thermodynamic considerations of the preferred reactions,w es ystematically designed as ynthesis process that preemptively converts residual Li 2 O(the origin of LiOH and Li 2 CO 3)into amore stable compound by injecting reactive SO 2 gas.T he preformed lithium sulfate thin film significantly suppresses the generation of LiOH and Li 2 CO 3 during both synthesis and storage,t herebym itigating slurry gelation and gas evolution and improvingthe cycle stability.

“…For realistic applications occurring in many aspects of daily life (including quick response (QR) codes, banknotes, identity cards, medicine, and consumer goods), cost, throughput, areal coverage, and flexibility/ conformability are important considerations. [16][17][18][19][20] Angular robustness is also one of the key factors for the successful recognition of encrypted information printed on curved or complex surfaces. [21,22] Achieving all of these features in a single photonic architecture is challenging.…”

Flexible, Large‐Area Covert Polarization Display Based on Ultrathin Lossy Nanocolumns on a Metal Film

Covert polarization displays provide a barrier to the inadvertent viewing of stored optical information. For security and anti‐counterfeiting purposes, access to concealed information without compromising packaging aesthetics is required in certain situations. However, optical conversion with polarized light typically requires sophisticated nanostructures only possible with limited materials, which are not appropriate for application to objects requiring flexibility or conformability, and color selectivity. A flexible, large‐area covert polarization display based on ultrathin lossy nanocolumns with wide color selectivity is presented. Self‐aligned porous nanocolumns (PNCs) fabricated by glancing angle deposition are a facile approach to polarization distinguishable structures. PNCs deposited on metal are designed to switch color in accordance with polarization by ultrathin resonance, which is modeled using the complex effective refractive index. Several combinations of material and thickness are presented to extend color selectivity with the standard red green blue gamut and color palette. As a demonstration, covert polarization display labels are attached to daily objects with curved and wrinkled surfaces, and hidden quick response codes are revealed by polarization adjustment in indoor and outdoor environments. Moreover, a multifunctional water contact detection covert polarization display is demonstrated based on the sensitivity of PNCs to the refractive index of the analyte.
