“…Such materials will not be suitable for long term, large scale operation, such as wastewater treatment, but they can be suitable for special, short-term applications, e.g. diagnostics (Fraiwan et al, 2013), biosensors (Fraiwan et al, 2014), biodegradable robots (Rossiter et al, 2016), wearable electronics (Taghavi et al, 2015) and emergency power supplies in remote locations (Winfield et al, 2015) where an ‘expiry date’ is desirable.…”

Microbial fuel cells (MFCs) with paper separators and liquid containing elements were investigated in supercapacitive mode. MFCs (15 mL) in a supercapacitive configuration, consisted of plain wrapped carbon veil anode (negative) and conductive latex cathode (positive). The internal supercapacitor is discharged galvanostatically and is self-recharged as red-ox reactions occur on both electrodes. MFCs were discharged at different current pulses varying from 1 mA to 7 mA. The MFCs had an equivalent series resistance of 41.2 ± 3.5 Ω caused mainly by the cathode. A maximum power of 1.380 ± 0.083 mW (0.092 ± 0.006 mW mL−1) was measured. Durability tests were conducted over 24 h collecting 1000 discharge cycles (0.5 s) and self-recharges (85 s) at a current of 1 mA. Over time the anode potential dropped causing a decline in performance perhaps due to evaporation of liquid from the pyramidal structure. Resistance and apparent capacitance measured during the durability test remained approximately constant during the cycles.

“…In connection with sustainability, biodegradable polymers should also be mentioned [49][50][51][52][53]. They are typically based on gelatin material, which shows similar mechanical properties as conventional silicone rubbers and can even be eaten after product use.…”

Soft robotics is a novel approach in the field of robotics. Soft robots or soft actuators are typically polymer-based and are characterized by their flexibility and adaptability, which brings new far-reaching applications. Soft robotics is currently at the peak of its research. One circumstance that is also present in this age is constant climate change; there is a demand for sustainability. This goes hand in hand with the design of products that are suitable for recycling. Today, more is expected of an engineer than just function-oriented design. This article looks at soft robotics from the point of view of sustainability. Since nature operates in cycles, the aim is to design products in such a way that they can be introduced into cycles. Three recycling cycles for products can be distinguished, which take place during production, during product use, and after product life. Within the framework of this work, special design measures are reviewed for fluidic elastomer actuators-a characteristic type of soft actuators-so that they can be integrated into the recycling process.

“…[22] Searching through the literature of the topic, the most recent publications are revolving around sensorics (K. Pal et al [23], Kanaparthi and Badhulika [24] Luvisi et al [25]). Rossiter et al recently claimed, the field of robotics will also implement and use biodegradables [26]. Deng et al investigated the life cycle assessment of flax-fibre reinforced epoxidized linseed oil composites [27] for electronics application.…”
