“…In general, working range and sensitivity are very important sensing performance indexes for strain sensors. [50][51][52][53][54][55] The aim of all strain sensors is to simultaneously achieve both high sensitivity and a wide sensing range. [51][52][53][54][55][56][57][58] Thus, the GF values and the maximum sensing strain ranges of the strain sensor reported recently are compared (Table S1, ESI †).…”

“…Specifically, it is assumed that stretching increases the resistance between adjacent AgNWs while also disrupting electron transport, resulting in a nonlinear GF. ,, Therefore, further research is required to secure the linearity of the GF of the sensitivity-adjusted strain sensors. Recently reported stretchable sensors are benchmarked in Table S1 to compare the sensor performances. ,− The results regarding the regulation of microcrack density and sensitivity by controlling SPO clarify that the most appropriate sensitivity can be selected according to the sensing purpose, and sensors with desirable sensitivity can be easily manufactured through SPO. It will be appropriate to use sensitive sensors, such as SPO-50, to detect small movements.…”

In this study, selective photo-oxidation (SPO) is proposed as a simple, fast, and scalable one-stop strategy that enables simultaneous self-patterning and sensitivity adjustment of ultrathin stretchable strain sensors. The SPO of an elastic substrate through irradiation time-controlled ultraviolet treatment in a confined region enables precise tuning of both the surface energy and the elastic modulus. SPO induces the hydrophilization of the substrate, thereby allowing the self-patterning of silver nanowires (AgNWs). In addition, it promotes the formation of nonpermanent microcracks of AgNWs/elastomer nanocomposites under the action of strain by increasing the elastic modulus. This effect improves sensor sensitivity by suppressing the charge transport pathway. Consequently, AgNWs are directly patterned with a width of 100 μm or less on the elastic substrate, and AgNWs/elastomer-based ultrathin and stretchable strain sensors with controlled sensitivity work reliably in various operating frequencies and cyclic stretching. Sensitivity-controlled strain sensors successfully detect both small and large movements of the human hand.

“…The cell structure parameters of polymer porous materials include cell morphology, porosity (density), cell size, and specific surface area. [103][104][105][106][107] These parameters cause a profound impact on the mechanical properties, thermal stability, dimensional stability, thermal insulation properties, and other special properties required by the application scenario (such as hydrophobic, filtration, gas barrier, and drug release) of the porous materials. [108][109][110] However, for PPMs, the crystallinity of Hc and Sc is also the main factor affecting their overall performance.…”

Recent advances in the cell structure regulation and performances improvement of porous poly(lactic acid) materials (PPMs) are systematically reviewed in this feature article. First, the typical processing methods, including template method, non‐solvent induced phase separation, freeze–drying, and supercritical CO2 foaming, of PPMs are introduced emphatically. Their various cell morphologies by different processing methods are summarized: finger–like, honeycomb–like, fiber–like, through cell, open cell, closed cell, ball–like, and flower–like. Meanwhile, the transformation among different cell morphologies as well as the changes in cell size and cell density, having impact on the performances, is described. Second, the influence of stereo–complex crystals on the cell structure of PPMs is emphatically reviewed. Furthermore, the relationships between cell structure and properties that includes mechanical properties, thermal stability, heat insulation, and hydrophobicity, are elaborated. Eventually, the issues of PPMs worthy of further study are discussed.
