“…Thus, several photocurable acrylate monomers and oligomers were chosen and used to fabricate 3D printed specimens for defining a triboelectric series. Some of the most used monomers in DLP printable formulations were thus selected, according to the literature, namely, PEGDA, , HDDA, and BEDA. , Moreover, a DLP printable PDMS-like silicone acrylate (i.e TEGORAD) was selected since polydimethylsiloxane (PDMS) is known for its elevate tribolectronegativity. , At last, commercial urethane acrylates, presenting different structures, were also evaluated (EBECRYL series), since polyurethanes have recently been proposed for the production of TENGs , and polyurethanes materials were exploited for DLP printing. − …”

Triboelectric nanogenerators (TENGs) represent intriguing technology to harvest human mechanical movements for powering wearable and portable electronics. Differently, compared to conventional fabrication approaches, additive manufacturing can allow the fabrication of TENGs with good dimensional resolution, high reproducibility, and quick production processes and, in particular, the obtainment of complex and customized structures. Among 3D printing technologies, digital light processing (DLP) is well-known for being the most flexible to produce functional devices by controlling both the geometry and the different ingredients of printable resins. On the other hand, DLP was not exploited for TENG fabrication, and consequently, the knowledge of the performance of 3D printable materials as charge accumulators upon friction is limited. Here, the application of the DLP technique to the 3D printing of triboelectric nanogenerators is studied. First, several printable materials have been tested as triboelectric layers to define a triboelectric series of DLP 3D printable materials. Then, TENG devices with increased geometrical complexity were printed, showcasing the ability to harvest energy from human movement. The method presented in this work illustrates how the DLP may represent a valuable and flexible solution to fabricate triboelectric nanogenerators, also providing a triboelectric classification of the most common photocurable resins.

“…[234] It is noteworthy that using a variety of biocompatible synthetic polymers, researchers have developed the construction of tissue scaffolds using VPP. [225,235] These polymers typi-cally contain carbonate or ester groups that are hydrolyzable under physiological conditions. [236] Poly(propylene fumarate) (PPF), the most extensively documented printed photopolymer for tissue scaffolds, is biocompatible and shows potential for usage in scaffolds for hard tissue replacement.…”

Nature frequently serves as an inspiration for modern robotics innovations that emphasize secure human–machine interaction. However, the advantages of increased automation and digital technology integration conflict with the global environmental objectives. Accordingly, biodegradable soft robots have been proposed for a range of intelligent applications. Biodegradability provides soft robotics with an extraordinary functional advantage for operations involving intelligent shape transformation in response to external stimuli such as heat, pH, and light. Soft robot fabrication using conventional manufacturing techniques is inflexible, time‐consuming, and labor‐intensive. Recent advances in 3D and 4D printing of soft materials and multi‐materials have become the key to enabling the direct manufacture of soft robotics with complex designs and functions. This review comprises a detailed survey of 3D and 4D printing advances in biodegradable soft sensors and actuators (BSSA), which serve as the most prominent parts of each robotic system. In addition, a concise overview of biodegradable materials for the fabrication of 3D‐printed flexible devices with medical along with industrial applications is provided. A complete summary of current additive manufacturing techniques for BSSA is discussed in depth. Moreover, the concept of biodegradable 4D‐printed soft actuators and sensors and biohybrid soft robots is reviewed.

“…As additive technologies continue to develop more rapidly, process improvements increasing the scope and feasibility of photopolymerization usage in 3D printing are being vigorously pursued by researchers. [30][31][32][33][34][35][36][37] 3D-VAT printing enables the production of three-dimensional polymer materials with a predetermined geometry while simultaneously having reasonable fabrication times and good control over the process. [38][39][40][41] In 3D-VAT printing, the type, amount, and form of the initiator/initiating system are particularly important for further applications.…”
