“…[15] A variety of high-performance ML materials have been developed in the last 30 years, some of which are practically applied. The most studied and promising inorganic ML compounds include SrAl 2 O 4 :Eu 2+ (green emitting), [31,[110][111] LiNbO 3 :Pr 3+ (red), [112][113][114] ZnS:Mn 2+ (orange), [93,115] ZnS:Cu (blue or green), [105,116] and (Ca,Sr)ZnOS:Ln 3+ (multicolor). [117][118] These materials exhibit bright and reproducible ML under stress.…”

“…These materials have attracted extensive attention and have greatly expanded the application field of ML materials in the last few years. Unfortunately, materials with self-reproducible ML similar to ZnS:Cu are limited to only ZnS:Cu/Mn 2+ [103,105,115,[193][194][195] and (Ca,Sr)ZnOS:Ln 3+ /Mn 2+ (Figure 6b-ii). [118,151,171,[196][197] In view of this, our group reported a route to develop new ML materials based on mixed-anion building units and developed two interesting compounds, SrZn 2 S 2 O:Ln 3+ and β-Sialon:Eu 2+ , with outstanding self-reproducible ML (Figure 6b-iii,iv).…”

Mechanoluminescence Rebrightening the Prospects of Stress Sensing: A Review

2021

Mechanoluminescence (ML) is the emission of light when a solid material is subjected to stress. [8][9] The intensity of the ML shows a strong correlation with the applied stress, making it suitable for stress sensing. ML stress sensing is based on a unique transduction principle from stress to photons, which paves the way for advanced stress sensing. In particular, ML-based sensing shows significant advantages of distributed detection and remote response to an applied stress by virtue of photon transmission through space. In addition, excellent stretchability, biocompatibility, and self-powering ability can be achieved within the stress-tophoton transduction units since electronic conduction is not needed. Importantly, ML-based sensing enables compensation of the shortcomings of conventional sensing technologies for emerging applications. Considering the many extraordinary performance characteristics, ML may hopefully rebrighten the prospects of stress sensing.Over the past few decades, ML materials and ML-based stress sensing have been extensively studied. Great efforts have been made to develop a large number of ML materials, deeply understand the ML mechanism, and boost the potential for stress sensing applications. Several review papers have been devoted to ML and its applications. [10][11][12][13][14][15][16][17] Bunzil and Wong summarized ML materials and stress sensors based on lanthanide compounds. [10] Xie and Li surveyed the progress in ML compounds with a focus on fractoluminescence. [11] An overview of inorganic ML compounds was presented by Feng and Smet, which particularly provides deep insight into the crystal structures and their relation to ML. [12] Additionally, Zhang et al. reviewed inorganic ML compounds, concentrating on their compositions, preparation, characterizations, mechanisms, and applications. [13] However, compared with materials and mechanisms, less attention has been paid to the technical performance of ML-based stress sensing and its relevance to applications. Obviously, reasonable analyses of the up-to-date performance are beneficial for properly assessing the potential for future applications.In this paper, we start with a brief overview of the desired performance characteristics of advanced stress sensing for several new applications (Section 2). The state-of-arts and challenges are highlighted. In Section 3, ML materials, ML-based sensors, and technical features will be discussed in an attempt to comprehensively evaluate ML-based sensing technology andThe emergence of new applications, such as in artificial intelligence, the internet of things, and biotechnology, has driven the evolution of stress sensing technology. For these emerging applications, stretchability, remoteness, stress distribution, a multimodal nature, and biocompatibility are important performance characteristics of stress sensors. Mechanoluminescence (ML)-based stress sensing has attracted widespread attention because of its characteristics of remoteness and having a distributed response to mechanical stimuli...

“…However, when the concentration was higher than 1.5 wt %, the intensity decreased as a result of the concentration quenching effect. 86 Thanks to the strong TL intensity, Xu et al further fabricated ZnS:Mn nanoparticles into an artificial skin film to sense mechanical stress by visible emission. 87 What is most exciting about this, as shown in Figures 14A-14C, is that the film responded to three different types of mechanical stress: shear stress by friction, compression stress by a material test machine, and impact stress by a free-falling ball with TL signals.…”

In this review, we survey the progress of triboluminescent compounds, which exhibit attractive emissions upon mechanical stimuli without the need for other stimulation or irritation. In particular, we present the research history, observed phenomena, proposed possible mechanisms, different types of triboluminescent compounds, and potential applications in an attempt to find the inherent clues hidden in the scattered literature. Accordingly, we provide some outlooks at the end of the paper for further exploration in this field.

Force-induced charge carrier storage: a new route for stress recording

et al. 2020

View full text Add to dashboard Cite

Stress sensing is the basis of human-machine interface, biomedical engineering, and mechanical structure detection systems. Stress sensing based on mechanoluminescence (ML) shows significant advantages of distributed detection and remote response to mechanical stimuli and is thus expected to be a key technology of next-generation tactile sensors and stress recorders. However, the instantaneous photon emission in ML materials generally requires real-time recording with a photodetector, thus limiting their application fields to real-time stress sensing. In this paper, we report a force-induced charge carrier storage (FICS) effect in deep-trap ML materials, which enables storage of the applied mechanical energy in deep traps and then release of the stored energy as photon emission under thermal stimulation. The FICS effect was confirmed in five ML materials with piezoelectric structures, efficient emission centres and deep trap distributions, and its mechanism was investigated through detailed spectroscopic characterizations. Furthermore, we demonstrated three applications of the FICS effect in electronic signature recording, falling point monitoring and vehicle collision recording, which exhibited outstanding advantages of distributed recording, long-term storage, and no need for a continuous power supply. The FICS effect reported in this paper provides not only a breakthrough for ML materials in the field of stress recording but also a new idea for developing mechanical energy storage and conversion systems.
