Mechanical quenching (MQ) represents a distinctive mechano-optical response, in which the afterglow intensity is quenched under the applied mechanical stress. Compared with mechanoluminescent (ML) materials, the research on physical mechanism and sensing application of MQ materials is still insufficient. Moreover, existing mechano-optical materials typically respond only to dynamic stress, while ML materials are unable to exhibit luminescence under static stress, restricting their utility in stress-sensing applications. In this work, the MQ characteristics of CaZnOS:Cu + are systematically studied, which displays a linear mechano-optical response to dynamic and static stress. Furthermore, this material shows a sensitive response to micro-strain in stretching tests. Therefore, a novel mechanical switch device is introduced combined with CaZnOS:Cu + and a ML material LiTaO 3 :Tb 3+ . By comparing the alteration in luminescence intensity during stretching, different stages of stress are digitally encoded, achieving both dynamic and static stress sensing and effectively differentiating the information output. These findings provide a new approach for multi-mode dynamic and static stress sensing by utilizing mechano-optical materials and pave a significant avenue for the information integration of mechano-optical materials in the field of stress sensing.

Dual-response mechanoluminescence (ML) enables light emission upon both the application and withdrawal of mechanical stress, which can provide novel opportunities for stress-sensing. Herein, we present the ML performance of doped ZnGa2O4–PDMS composites with a focus on the dual-response ML behavior upon the dynamic stretching–releasing cycle. Specifically, it was found that the dual-response ML behavior of ZnGa2O4 is doping dependent, which was further proved to be related to doping induced trap distribution. Finally, ZnGa2O4:Mn/PDMS with dual-response ML was used as an electronic skin to demonstrate its unique potential for stress-sensing applications.

Optical polyimide (PI) membranes have been increasingly attractive in optoelectronic substrate and optical element material applications. Controlled stress distribution is very important to optical PI membrane-based optics. However, nondestructive absolute stress measurement inside optical PI membranes remains challenging. In this letter, we adopted the stress birefringence method to experimentally investigate the correlation between stress and retardation in uniaxially, biaxially, and circularly stretched PI membranes. The calculated value of the photoelastic coefficient was found to be around 400 nm/Mpa·cm. A theoretical model was established where the retardation angle is the negative arctan of the principal stress ratio in the biaxially stretched membrane. We also found that the average retardation angle is an important parameter for evaluating the uniformity of stretching force in the circularly stretched membrane. This work provides a better understanding of the stress birefringence measurement of membrane materials.Keywords:optical polyimide membrane;stress analysis;photoelastic property;stress birefringence

Purpose Gabapentin (GBP) is an anticonvulsant drug with poor chemical stability that is particularly sensitive to heat and mechanical stress, which can lead to intramolecular lactamization. The purpose of this study was to enhance the chemical stability of GBP by cocrystallization with organic acids. Method Two novel multicomponent crystals, GBP-2,6-pyridinedicarboxylic acid salt (GBP-2,6PDA salt) and GBP-2,5-pyridinedicarboxylic acid cocrystal (GBP-2,5PDA cocrystal) were synthesized and characterized by various solid-state analytical techniques. The degradation behavior of GBP, GBP-2,6PDA salt and GBP-2,5PDA cocrystals were evaluated under thermal and mechanical stresses. Result Under thermal and mechanical stresses, GBP-2,5PDA cocrystals were found to undergo severer degradation than GBP-2,6PDA salt and neat GBP. GBP-2,6PDA salt exhibited superior chemical stability compared to the others. Furthermore, the crystal structure revealed that the order of atomic distance between the carboxyl group (C7) and amino group (N12) of GBP is as follows: GBP-2,5PDA cocrystal < GBP < GBP-2,6PDA salt, which is consistent with the chemical stability of GBP in different solid forms. Therefore, we believe that the distance between C7 and N12, the reaction active sites leading to dehydrative condensation of GBP, is a key factor determining the chemical stability of GBP in the solid state. Conclusions These results provide a potential method to improve the chemical stability of GBP during the manufacturing process and storage.

Elastico-mechanoluminescence technology has shown significant application prospects in stress sensing, artificial skin, remote interaction, and other research areas. Its progress mainly lies in realizing stress visualization and 2D or even 3D stress-sensing effects using a passive sensing mode. However, the widespread promotion of mechanoluminescence (ML) technology is hindered by issues such as high stress or strain thresholds and a single sensing mode based on luminous intensity. In this study, a highly efficient green-emitting ML with dual-mode stress-sensing characteristics driven by microscale strain is developed using LiTaO 3 :Tb 3+ . In addition to single-mode sensing based on the luminous intensity, the self-defined parameter ( Q ) is also introduced as a dual-mode factor for sensing the stress velocity. Impressively, the fabricated LiTaO 3 :Tb 3+ film is capable of generating discernible ML signals even when supplied with strains as low as 500 µst. This is the current minimum strain value that can drive green-emitting ML. This study offers an ideal photonic platform for exploring the potential applications of rare-earth-doped elastico-ML materials in remote interaction devices, high-precision stress sensors, and single-molecule biological imaging.

Stress as an important parameter of thin films can seriously affect on the properties, performance and long-term stability of the films. Here, we propose a semiquantitative method based on Raman spectroscopy for the stress measurement on nonstoichiometric ceria oxide films . The “chemical strain” of lattice caused by oxygen deficits was a main obstacle factor for the stress measurement of CeO 2−δ films, which was overcome through the calibration of lattice vibration peaks by the normalized intensity of Ce 3+ ions in Raman spectra . A compressive stress about −1.38 ∼ −1.50 GPa was obtained on an oxidated Ce film, which was verified by the substrate-curvature method. Based on the proposed method, Raman spectroscopy could be expanded to wider application fields as an in-situ stress measurement tool, such as in the fields of oxygen-ion-conducting solid electrolytes , oxidation film of alloys, microelectronics and MEMS devices, etc.

Blood vessel is one of the ‘pathways’ for cancer to metastasize, in which cells are exposed to the fluid shear stress. Although most cells are damaged by fluid shear stress, a small number of tumor cells survive and metastasize when they are exposed to low shear stress (LSS) of tiny capillary. It is important to study the survival state of damaged cells during LSS. In this study, high shear stress (HSS) was applied to simulate the blood circulation and damage cells. The viability and mitochondrial function of cells were detected after HSS and LSS loading, respectively. Further, the expression of mitochondrial related proteins and genes were detected by western blot and real-time quantitative polymerase chain reaction, respectively. The role of cytochrome c (Cyt C) was also verified in this process. The experimental results showed that the viability of HSS damaged cells was increased significantly when they were exposed to LSS subsequently. The function of mitochondria was improved via reducing the release of Cyt C by LSS during this process. This study is expected to provide potential target for suppressing hematogenous metastasis.

The adhesion of soft materials often fails due to stress concentration at the interface. Structural design offers an effective approach to disperse stress at the interface and enhance adhesion properties. Herein, we introduce the concept of discretized stress dispersion to achieve ultrastrong adhesion of soft materials. This involves incorporating discrete structures at the adhesion interface, with each unit structure designed to efficiently disperse stress. We implement this concept by introducing periodic strategic cuts into the adhesive, enabling it to deform into discrete mushroom-shaped structures under peel forces. Utilizing fracture mechanics theory, we demonstrate that such structural design can significantly improve adhesion strength compared to adhesives without structural design. Through 3D printing, we fabricate adhesive samples with strategic cuts, achieving a peak peel force of 3479 N/m, over 100-fold higher than adhesives without cuts (25 N/m). We analyzed stress dispersion of each unit structure through experiments of with different geometric parameters and analyze collaborative effects of multiple structures with theoretical model. Finite element analysis of the peel process highlights the critical role of cohesive zone influenced by geometric parameters, which determines the peak peel force. This concept of discretized stress dispersion advances the development of soft materials with ultrastrong adhesion.

Recently, mechanical biosensors have attracted more attention on single molecule detection due to its high accuracy, low cost, and convenience. However, the sensitivity of the mechanical biosensors restricted their clinical application. Herein, a mechanical biosensor based on membrane-mediated magneto-stress-electric coupled sensitization (MSEC-MMB) was developed to enhance performance. Through introducing Fe3O4 nanoparticles (MNPs) to traditional stress-electric biosensors and applying a magnetic field, a magneto-stress-electric coupled biosensing system was constructed. The sensitivity of the MSEC-MMB was improved via enhancing the deformation of the mechanical membrane, which was demonstrated by detecting HSA. The optimal limit of detection (LOD) was 24 pg mL−1 under a magnetic field of 50 mT. The LOD was significantly 1 order of magnitude lower than that without the magnetic field. Besides, the MSEC-MMB showed a high specificity, selectivity, and stability. The clinical proteinuria samples were accurately detected, suggesting a good practicability of the MSEC-MMB. All these results proved the high sensitivity and practicality of the MSEC-MMB and provide a platform for early nephropathy diagnosis.

Sluggish kinetics limit the practical application of sodium-ion batteries (SIBs); thus, innovative strategies and the design of materials with fast reaction kinetics are important for the development of SIBs. To solve these issues, the innovative strategy of using a micro-stress pump to boost Na+ transport by simulating rhythmic cardiac blood pumping has proposed for the first time. A smart material with cardiac-like behavior promotes the electrochemical kinetics through the self-regulation of stress under the variation of voltage in the redox reaction. Under the micro-stress field, a half-cell demonstrates a capacity of 119.1 mA h g−1 at 35 A g−1, and a 1.04 A h pouch cell shows an excellent energy density of 317.2 W h kg−1 (the retention is 90.2% after 500 cycles at 1C). Via further analysis of physicochemical characterizations and the sensor signal, the signal correlation of the mechanism between electrochemistry and stress was obtained. This work provides a strategy for accelerating the transmission rate of Na+ based on a stress field.

Mechanical luminescence (ML) is the conversion of mechanical energy into light energy when a material is subjected to a force. It is challenging to develop ML materials with tunable luminescent properties by single ion doping, which have broad application prospects in the fields of stress sensing and dynamic signature anticounterfeiting. In this study, a Pr 3+ doped Sr 2 Ga 2 GeO 7 tunable ML material is reported. Due to the traps resulting from unequal substitution of Pr 3+ –Sr 2+ in [SrO 6 ] heptahedra, the deep/shallow traps redistribution occurs towards a multicolor ML from red to green. In addition, even after continuous friction sliding force (15 N), the ML intensities can be recovered after ultraviolet pre-irradiation, indicating that Sr 2 Ga 2 GeO 7 : Pr 3+ has excellent ML emission stability. Based on thermoluminescence analysis, potential PersL and ML mechanisms are further elaborated by a lattice engineering (trap regulation) strategy. In all, the development of single-ion doped multicolor ML materials may have crucial research value and show a variety of potential applications in the fields of anticounterfeiting and information encryption.
