“…It is very effortful to reach to high TRL and asses it. In Reference [76], it was demonstrated that for the full assessment of the TRL of SMAs, mechanical, magnetic, corrosion resistance, and biocompatibility had to be considered.…”

In this systematic survey, an overview of non-conventional actuators particularly used in soft-robotics is presented. The review is performed by using well-defined performance criteria with a direction to identify the exemplary and potential applications. In addition to this, initial guidelines to compare the performance and applicability of these novel actuators are provided. The meta-analysis is restricted to five main types of actuators: shape memory alloys (SMAs), fluidic elastomer actuators (FEAs), shape morphing polymers (SMPs), dielectric electro-activated polymers (DEAPs), and magnetic/electro-magnetic actuators (E/MAs). In exploring and comparing the capabilities of these actuators, the focus was on eight different aspects: compliance, topology-geometry, scalability-complexity, energy efficiency, operation range, modality, controllability, and technological readiness level (TRL). The overview presented here provides a state-of-the-art summary of the advancements and can help researchers to select the most convenient soft actuators using the comprehensive comparison of the suggested quantitative and qualitative criteria.

“…Within this scenario, Fe-based alloys have gained increasing attention because of their mechanical properties, slower degradation rates and the good preliminary results obtained in in-vitro and in-vivo experiments [1,2]. For instance, recent studies showed that FeMn [3][4][5][6][7][8][9], FeMnPd [3,4], and FeMnSi [7] systems exhibit viable degradation rates and mechanical properties similar to those of 316L stainless steel. In particular, in our previous study on Fe-10Mn-6Si-1Pd alloy, a hardness value around 5.6 GPa and a reduced Young's modulus of 125 GPa were reported [8].…”

“…Concerning biocompatibility, the bulk alloy showed good initial cell adhesion. However, the pronounced ion release due to the formation of a cracked, loosely attached superficial oxide layer, hampered the cell proliferation on the surface of this alloy [8]. Nonetheless, no toxic effect has been observed due to local accumulation of Fe degradation products (i.e.…”

“…[1][2][3][4] Some of the possible alloys for such applications, especially in orthopaedics (bone-fixation screws, pins, plates, disks), are those based on Fe. [5][6][7][8][9][10][11][12][13] At the beginning of the healing process, injuries need stable mechanical properties to provide sufficient support. However, as the healing process progresses, the mechanical properties of the implants can be reduced, until finally they are no longer required.…”

In this study we report the influence of laser ablation on the controlled biodegradability of a Fe-Mn alloy developed for medical implants. After texturing by a nanosecond Nd:YAG laser, the surface expressed extreme super-hydrophilic wetting properties, since laser ablation led to micro-channels and chemical modification resulting in nanostructured metal oxides. The influence of functionalized surface properties on corrosion behaviour was examined on molecular level by using X-ray photoelectron spectroscopy. Results reveal that the oxide layer after the laser texturing of Fe-Mn alloy consists mainly of Fe 2 O 3 and FeO, with the content of Mn in the oxide layer being significantly higher than in the bulk. The results of the electrochemical measurements clearly demonstrate the superior biodegradability of the Fe-Mn alloy samples functionalized by laser ablation. Here, the laser-triggered corrosion is selfdriven by further production of corrosion products that leads to biodegradability of the whole sample.
