“…Alternatively, when piezoelectric materials are subjected to an electrical field, mechanical strain is generated and they deform. Therefore, this group of materials has been found particularly useful for fabrication of electronic devices, sensors, actuators, and energy harvesting devices. , Materials with the strongest piezoelectric effects ( d 33 > 200 pCN –1 ) are usually ceramics. However, despite their pronounced piezoelectricity, they are brittle, often contain environmentally unfriendly lead, and exhibit a limited processing potential.…”

“…Another approach for manufacturing piezoelectric devices relies on the utilization of piezoelectric polymers, PVDF in particular. ,− Despite its inferior piezoelectric activity compared to ceramics, PVDF derives the benefit of easier processability, improved flexibility, and biocompatibility, making it an attractive candidate for 3DP. PVDF is a semicrystalline polymer that has at least 4 phases (α, β, γ, δ), among which β-phase exhibits the strongest piezoelectric response .…”

Three-dimensional printing (3DP) has attracted a considerable amount of attention during the past years, being globally recognized as one of the most promising and revolutionary manufacturing technologies. Although the field is rapidly evolving with significant technological advancements, materials research remains a spotlight of interest, essential for the future developments of 3DP. Smart polymers and nanocomposites, which respond to external stimuli by changing their properties and structure, represent an important group of materials that hold a great promise for the fabrication of sensors, actuators, robots, electronics, and medical devices. The interest in exploring functional materials and their 3DP is constantly growing in an attempt to meet the ever-increasing manufacturing demand of complex functional platforms in an efficient manner. In this review, we aim to outline the recent advances in the science and engineering of functional polymers and nanocomposites for 3DP technologies. The report covers temperature-responsive polymers, polymers and nanocomposites with electromagnetic, piezoresistive and piezoelectric behaviors, self-healing polymers, light- and pH-responsive materials, and mechanochromic polymers. The main objective is to link the performance and functionalities to the fundamental properties, chemistry, and physics of the materials, and to the process-driven characteristics, in an attempt to provide a multidisciplinary image and a deeper understanding of the topic. The challenges and opportunities for future research are also discussed.

“…A transformative additive manufacturing-based novel process was presented to fabricate freeform-shaped volumetric piezoelectric devices by combining additive manufacturing and electric poling processes in a single processing and fabrication step. The poling-assisted additive manufacturing process can align the dipoles of the polymer molecular chain and transform the polymer from the α phase to the β phase by applying a strong electric field during printing [40,41].…”

“…Often the material is polarised after the fabrication process in order to increase the piezoelectric constant [97]. The formation of the piezoelectric β-crystal structure of PVDF can be enhanced by printing with a high voltage applied between the nozzle and the bed, as shown in [97], [98]. It should be noted that an effect similar to that of a piezoelectric material can be achieved using an electret, which can be 3D printed as well [99].…”

In this review paper, we focus on the 3D printing technologies that consist of the extruding of fluid material in lines to form structures for electro-and biomechanical applications. Our paper reviews various 3D print technologies, materials, sensing technologies and applications of extrusion-based 3D printing. We also discuss how to overcome some of the challenges with 3D printed sensors, such as the anisotropy of the conductors as well as the drift and nonlinearity of the materials.
