“…The amount of charge generated depends on the difference in triboelectricity polarities between the two contacted materials (Sun et al, 2018). Haque et al (2018) used several printable soft materials as functional triboelectric sensor components. They found that PDMS, combined with commercial TangoBlack (TB), showed the highest triboelectric responses.…”

Soft tactile sensors (STSs) combine the flexibility and the converting ability between mechanical forces and electrical signals. 4D printing was first introduced in 2013, and attracted great interest because of its versatile functionalities in actuators, artificial muscles, STSs, soft energy harvesting, pneumatic nets, electroactive polymers, and soft electronics. Using the 4D printing concept to fabricate STSs is promising, yet it is at its infant stage. At present, researchers have utilized two types of strategies: one is directly using smart materials through 3D printing manufacturing, and the other is programming codes of components and structures to create controllable changes. This review summarizes the recent research on 4D printing toward STSs and discusses the future perspectives of this emerging field.

“…ABS-5% L/0.50%GnP had an average surface roughness of 8.33 μm (86% increment compared to neat ABS), which is considerably smooth compared with other studies. [47] Surface roughness affects the contact angle of the printed sample, and incorporation of lignin and GnP that are hydrophobic would eventually increase the contact angle of the 3D-printed sample that might be useful for a hydrophobic application like coatings and circuits. [48,49] GnPs had more effect on the hydrophobicity of the printed sample than lignin as ABS-1.0%GnP had an average contact angle of 92.3 o compared with ABS-1.0%L that had an average contact angle of 86.3 o similar to ABS that has a contact angle of 86.0 o .…”

The attention to pursuing biodegradable fillers as reinforcement in three-dimensional (3D) printing filament and enhancing interlayer adhesion has led to the exploitation of agricultural biomass. In this study, organosolv lignin fillers can act as the aforementioned twofold purposes in preparing acrylonitrile butadiene styrene (ABS) filament for fused deposition modeling (FDM). In this study, the lignin polymer composites were homogenized with graphene nanoplatelets (GnPs) as a reinforcer. Essentially, ABS 3D printing at 90 o with the reinforcement fillers shows a significant increment in the mechanical properties owing to better interlayer adhesion. The printed product promotes a substantial improvement on the tensile stress up to 29.1% compared with neat polymers. Furthermore, 3D printing using lignin/GnP composite filaments shows the feasibility of biofillers to be used as filaments for FDM 3D printing of complex geometries even though the surface finish has been affected.

“…Owing to the air gap between them, the opposite charges on surfaces create a potential difference. These are mechanical energy harvesting devices; in other words, it enables to monitor touch action without the necessity of external power supply [200]. Triboelectric generators demonstrate excellent compatibility with the printing fabrication techniques as its fundamental structural components are printable without compromising on the device performance.…”

Flexible and stretchable tactile sensors that are printable, nonplanar, and dynamically morphing are emerging to enable proprioceptive interactions with the unstructured surrounding environment. Owing to its varied range of applications in the field of wearable electronics, soft robotics, human-machine interaction, and biomedical devices, it is required of these sensors to be flexible and stretchable conforming to the arbitrary surfaces of their stiff counterparts. The challenges in maintaining the fundamental features of these sensors, such as flexibility, sensitivity, repeatability, linearity, and durability, are tackled by the progress in the fabrication techniques and customization of the material properties. This review is aimed at summarizing the recent progress of rapid prototyping of sensors, printable material preparation, required printing properties, flexible and stretchable mechanisms, and promising applications and highlights challenges and opportunities in this research paradigm.
