“…[190][191][192][193][194][195] The phosphors are usually embedded in transparent binders, such as resins or glasses to facilitate stress transfer to the phosphor microparticles. While it is known that external stress can generate charge carriers at the surface of the binder or at the binder-phosphor interfaces which can ultimately result in luminescence, [196][197][198] in the following we will only focus on recoverable mechanoluminescence upon elastic deformation (sometimes called elasticoluminescence), a process that is directly related to the charge trapping in some persistent phosphors. [192,199] This process is quite similar to TL or OSL as the application of a mechanical stimulus can induce detrapping which leads to luminescence but only when the phosphor is exposed to excitation light first.…”

Glow-in-the-dark materials have been around for a long time. While formerly materials had to be mixed with radioactive elements to achieve a sufficiently long and bright afterglow, these have now been replaced by much safer alternatives. Notably strontium aluminate, SrAl 2 O 4 , doped with europium and dysprosium, has been discovered over two decades ago and since then the phosphor has transcended its popular use in watch dials, safety signage, or toys with more niche applications such as stress sensing, photocatalysis, medical imaging, or flicker-free light-emitting diodes. A lot of research efforts are focused on further improving the storage capacity of SrAl 2 O 4 :Eu 2+ ,Dy 3+ , including in nanosized particles, and on finding the underlying physical mechanism to fully explain the afterglow in this material and related compounds. Here an overview of the most important results from the research on SrAl 2 O 4 :Eu 2+ ,Dy 3+ is presented and different models and the underlying physics are discussed to explain the trapping mechanism at play in these materials.

“…6 Flexible and self-powered electronic skin (E-Skin) based on a hyperscalable turboelectric nanogenerator has been leading the way in the development direction of tactile sensing. 7 However, since the transmission of E-Skin information must rely on a complete circuit design, it must be indirectly contacted with the object to be measured. 8 Limited sensor integration technology, low spatial resolution, and invisible sensor information limit the application and development of electronic skin in mechanical sensing.…”

Tactile sensing with stress and temperature sensing as core elements have shown promising prospects in intelligent robots and the human–machine interface. Mechanoluminescence (ML)-based stress sensing can realize the direct sensing of mechanical stimulation, whereas indirect temperature sensing based on luminescent sensing materials usually requires the stimulation of extra light or force. Herein, a trap-controlled material Sr2MgAl22O36:Mn2+ with bifunctional mechano/thermal sensing applications was developed and investigated in detail. Visualized bright green-emitting ML and thermally stimulated luminescence (TSL) directly and rapidly responded to mechano/thermal dual stimulation in the Sr2MgAl22O36:Mn2+/PDMS composite film. It is worth mentioning that this study proposed a new idea of direct temperature sensing by the initial intensity of TSL due to thermal–photo energy conversion, unlike previous temperature sensor technology. Based on this, we designed a flexible optical skin with a simple structure and verified its application prospect as a tactile sensing material with dual mechano/thermal response, establishing a unique imaging mode and providing a convenient, reliable, and sensitive way to remotely visualize the distribution of stress and temperature. This study paves a new way for the development of optical skins with simple structures and sensitive visibility in the application of intelligent robot tactile sensing.
