Many forward‐looking biomedical, pharmaceutical, and food industry technologies have limited applications owing to the lack of crucial factors: balance of safety and reliability, cost‐efficiency, and suitability for self‐healthcare monitoring. The newly minted field of edible electronics, while at an embryonic stage, is creating great scientific resonance by envisioning a technology which is safe for ingestion, environmentally friendly, cost‐effective, and degraded within the body after performing its function, either digested or even metabolized. Yet there is no shared approach, and the field is currently unified only by the use of food‐derived or edible synthetic functional materials. In order to help shape the field more consistently, the main ideas and perspectives that have been proposed in the recent past are critically curated, underlining what edible electronics is and will be in the future according to the vision. Long‐term opportunities in terms of environmentally friendly smart technologies, remote healthcare monitoring, and the formidable challenges ahead are discussed, covering major issues with respect to safety, materials approval, processing, power supply, communication, and human body interaction. A key point in moving toward such a vision is a strong interdisciplinary cooperation, which is highly encouraged.

The modeling of soft structures, actuators, and sensors is challenging, primarily due to the high nonlinearities involved in such soft robotic systems. Finite element modeling (FEM) is an effective technique to represent soft and deformable robotic systems containing geometric nonlinearities due to large mechanical deformations, material nonlinearities due to the inherent nonlinear behavior of the materials (i.e., stress-strain behavior) involved in such systems, and contact nonlinearities due to the surfaces that come into contact upon deformation. Prior to the fabrication of such soft robotic systems, FEM can be used to predict their behavior efficiently and accurately under various inputs and optimize their performance and topology to meet certain design and performance requirements. In this article, we present the implementation of FEM in the design process of directly three-dimensional (3D) printed pneumatic soft actuators and sensors to accurately predict their behavior and optimize their performance and topology. We present numerical and experimental results to show that this approach is very effective to rapidly and efficiently design the soft actuators and sensors to meet certain design requirements and to save time, modeling, design, and fabrication resources.

“…Sencadas et al. [ 229 ] showed recently that degradable elastomeric porous PGS could be used as a sensitive piezoresistive sensor with enhanced electromechanical performance. PGS was blended with multiwalled carbon nanotubes (MWCNTs) and NaCl to generate a porous structure, which could handle an extensive range of pressures (<8 kPa).…”

Poly(glycerol sebacate) (PGS) continues to attract attention for biomedical applications owing to its favorable combination of properties. Conventionally polymerized by a two‐step polycondensation of glycerol and sebacic acid, variations of synthesis parameters, reactant concentrations or by specific chemical modifications, PGS materials can be obtained exhibiting a wide range of physicochemical, mechanical, and morphological properties for a variety of applications. PGS has been extensively used in tissue engineering (TE) of cardiovascular, nerve, cartilage, bone and corneal tissues. Applications of PGS based materials in drug delivery systems and wound healing are also well documented. Research and development in the field of PGS continue to progress, involving mainly the synthesis of modified structures using copolymers, hybrid, and composite materials. Moreover, the production of self‐healing and electroactive materials has been introduced recently. After almost 20 years of research on PGS, previous publications have outlined its synthesis, modification, properties, and biomedical applications, however, a review paper covering the most recent developments in the field is lacking. The present review thus covers comprehensively literature of the last five years on PGS‐based biomaterials and devices focusing on advanced modifications of PGS for applications in medicine and highlighting notable advances of PGS based systems in TE and drug delivery.
