“…These studies also showed that BCP is more bioactive than pure HA or TCP [16]. In this way, BCP emerges by showing a huge potential to practical applications in human bone substitution and can be combined with other materials to become a multifunctional material [17].…”

A ceramic/polymer biocomposite with high potential for multifunctional practical applications in bone tissue engineering was synthesized by using a well-known piezoelectric polymer, polyvinylidene fluoride (PVDF), and a high bioactive biphasic calcium phosphate (BCP) ceramic obtained from recycled fish bones. High-bioactivity was observed for the PVDF-BCP composite when it was subjected to conditions that simulate the animal body once a very thick apatite layer (9 μm) was grown on its surface in an immersion experiment (7 days) in simulated body fluid. The structural characteristics of the PVDF-BCP composite showed similarities with highly bioactive young animal bones, overlapped with PVDF polymorphic phases. Mechanical tests revealed properties very similar to those of the human bone tissue with a resistance strength reaching 80 MPa. Together, all these factors indicated a very promising material for application in osseous implants/replacement with postoperative recovery controlled/ accelerated by external stimuli.

“…Multifunctional materials are attractive because they may combine properties, which allow manipulation chemical functionalities, playing a key role in different applications. The use of multifunctional materials will, and in some cases already do, allow savings in number of parts, reducing the need for joining operations 9 . Moreover, materials that present both magnetic and luminescent properties have been developed [10][11][12][13][14] and applied to biotechnological processes such as imaging, tracking, and separation of biological molecules or cells [15][16][17][18][19] .…”

Magnetite was doped with rare earth ions (europium) to produce core-shell materials with both magnetic and luminescent properties, i.e., a magnetic Fe 3 O 4 oxide core and a SiO 2 :phen:Eu 3+ shell. The resulting material was analyzed by X-ray powder diffraction and transmission electron microscopy, and subjected to magnetic and luminescence emission measurements. All the synthesized materials exhibited superparamagnetic behavior and luminescence emission. The magnetic behavior of Fe 3 O 4 and luminescence emission of SiO 2 :phen:Eu 3+ of the materials were compared to precursors.

“…With the common use of SMAs and SMPs as actuators, it would not be difficult to implement them as reinforcing structural elements in damage resilient soft robots (Kirkby et al, 2008;Ferreira et al, 2016). Huang et al (2010) demonstrated the feasibility of this by embedding a coiled SMA wire inside of a semiflexible, self-healing polymer (Figures 3D,E).…”

Advances in soft robotics will be crucial to the next generation of robot-human interfaces. Soft material systems embed safety at the material level, providing additional safeguards that will expedite their placement alongside humans and other biological systems. However, in order to function in unpredictable, uncontrolled environments alongside biological systems, soft robotic systems should be as robust in their ability to recover from damage as their biological counterparts. There exists a great deal of work on self-healing materials, particularly polymeric and elastomeric materials that can self-heal through a wide variety of tools and techniques. Fortunately, most emerging soft robotic systems are constructed from polymeric or elastomeric materials, so this work can be of immediate benefit to the soft robotics community. Though the field of soft robotics is still nascent as a whole, self-healing and damage resilient systems are beginning to be incorporated into three key support pillars that are enabling the future of soft robotics: actuators, structures, and sensors. This article reviews the state-of-the-art in damage resilience and self-healing materials and devices as applied to these three pillars. This review also discusses future applications for soft robots that incorporate self-healing capabilities.
