“…This bio-battery exhibited slightly lower middle point voltages and capacities (1.29-1.06 V, 4.42-0.93 mA h cm -2 ) than the previously reported result with electrodeposited PPy-pTS cathode on SS mesh. [34] Nevertheless, it delivered a much higher stable voltage and specific capacity than those (0.4-0.7 V, 2.4 mA h cm -2 ) from recently reported biodegradable Mg-Mo battery. [9] We further investigated the rate capability ( Figure 5b) at the range of 5 to 100 µA cm -2 .…”

Biodegradable active implantable devices can be used to diagnose and/or treat disease and eventually disappear without surgical removal. If an "external" energy source is required for effective operation then a biocompatible and biodegradable battery would be ideal. In this study, a partially biodegradable Mg-air bioelectric battery (biobattery) is demonstrated using a silk fibroin-polypyrrole (SF-PPy) film cathode coupled with bioresorbable Mg alloy anode in phosphate buffered saline (PBS) electrolyte. PPy is chemically coated onto one side of the silk substrate. SF-PPy film shows a conductivity of ≈1.1 S cm−1 and a mild catalytic activity toward oxygen reduction. It degrades in a concentrated buffered protease XIV solution, with a weight loss of 82% after 15 d. The assembled Mg-air biobattery exhibits a discharge capacity up to 3.79 mA h cm−2 at a current of 10 μA cm−2 at room temperature, offering a specific energy density of ≈4.70 mW h cm−2. This novel partially biodegradable battery provides another step along the route to biodegradable batteries.

The assembled Mg-air biobattery exhibit a discharge capacity up to 3.79 mA h cm -2 at a current of 10 µA cm -2 at room temperature, offering a specific energy density of ∼4.70 mW h cm -2 . This novel partially biodegradable battery provides another step along the route to biodegradable batteries.

Chitin and chitosan are widely found in nature. Chitin can be obtained from fungi and in the lower animals. Chitosan can be derived from chitin. The process of chitosan derivation from chitin is called deacetylation. Chitosan is non-toxic, odourless, biocompatible in animal tissues and enzymatically biodegradable. It has found many applications in the fields of cosmetics, wound healing, dietetics and waste-water treatment. Chitosan holds many promising potentials, but its inability to dissolve in many of the common solvents has restricted its application. Hence, chitosan has been modified, and there are now many derivatives of chitosan. In the current chapter, we discuss chitosan and only the phthaloyl chitosan derivative. Their applications in several electrochemical devices are also discussed.

“…Coupled with biocompatible thin‐film cathode materials (e.g., platinum (Pt), copper (Cu), gold (Au), polypyrrole (PPy)), the constructed galvanic cells can offer electrical power through the electrochemical dissolution process of the active materials (Mg, Zn). Biofluids or biopolymer materials serves as the electrolyte, which circumvents the usage of hazardous solvents as that in general lithium‐ion battery . A miniaturized and flexible Mg–Cu and Zn–Cu galvanic cell, reported by Nadeau et al, is shown in Figure a .…”

Implantable bioelectronics represent an emerging technology that can be integrated into the human body for diagnostic and therapeutic functions. Power supply devices are an essential component of bioelectronics to ensure their robust performance. However, conventional power sources are usually bulky, rigid, and potentially contain hazardous constituent materials. The fact that biological organisms are soft, curvilinear, and have limited accommodation space poses new challenges for power supply systems to minimize the interface mismatch and still offer sufficient power to meet clinical‐grade applications. Here, recent advances in state‐of‐the‐art nonconventional power options for implantable electronics, specifically, miniaturized, flexible, or biodegradable power systems are reviewed. Material strategies and architectural design of a broad array of power devices are discussed, including energy storage systems (batteries and supercapacitors), power devices which harvest sources from the human body (biofuel cells, devices utilizing biopotentials, piezoelectric harvesters, triboelectric devices, and thermoelectric devices), and energy transfer devices which utilize sources in the surrounding environment (ultrasonic energy harvesters, inductive coupling/radiofrequency energy harvesters, and photovoltaic devices). Finally, future challenges and perspectives are given.
