Abstract Almost all implantable electronic medical devices (IEMDs) are powered by bulky Li‐ion batteries (LIBs), limiting their miniaturization and lifespan advancements. In addition, LIBs contain toxic materials flammable electrolytes that dangerous if they leak into human organs. this context, there is an urgent need to explore new approaches concepts can address the critical challenges of designing novel electrochemical energy storage systems gain a mechanistic understanding phenomena taking place in diverse scenarios. This review summarizes recent advancements biocompatible supercapacitors (B‐SCs) as power source for various IEMDs, offering potential solution these challenges. Different types IEMDs requirements briefly discussed, along with arising from applications IEMDs. Given importance electrode determining performance B‐SCs terms densities, different developments systematically reviewed. Finally, insights offered opportunities future prospects rational design next‐generation B‐SCs.

With the rapid advancement of implantable electronic medical devices, supercapacitors have emerged as popular energy storage devices. However, inevitably come into direct contact with blood when implanted, potentially causing adverse clinical reactions such coagulation and thrombosis, impairing performance implanted posing a serious threat to human health. Therefore, this work aims design an anticoagulant supercapacitor by heparin doped poly(3, 4-ethylenedioxythiophene) (PEDOT) for possible applications in bioelectronics. Heparin (Hep), as-known macromolecule acts counterion PEDOT doping enhance its conductivity, bioelectrode material PEDOT: Hep activity is synthesized via chemical oxidation polymerization. Concurrently, constructed through in-situ polymerization, where bacterial cellulose electrode electrolyte layer, respectively. Owing incorporation heparin, exhibits high hemocompatibility hemolysis rate <5 %, good time 63.4 s, reasonable cycle stability capacitance retention 76.24 % after 20, 000 cycles, supplies power heart sensors female mice. This provides platform electronics achieve vivo. Implantable are promising use supply devices within body, but their utility hindered thrombosis. Here, authors report that properties cycling stability.

Poly(3, 4-ethylenedioxythiophene) (PEDOT) as a new generation of intelligent conductive polymers, is attracting much attention in the field tissue engineering. However, its water dispersibility, conductivity, and biocompatibility are incompatible, which limit further development. In this work, biocompatible electrode material PEDOT doped with sodium sulfonated alginate (SS) contains two functional groups sulfonic acid carboxylic per repeat unit macromolecule. The dual-site doping strategy simultaneously boosts anticoagulant electrochemical performances, for example, good hydrophilicity (water contact angle 59.40°), well dispersibility (dispersion solution unstratified 30 days), high conductivity (4.45 S m

Abstract With the rapid development of implantable electronic medical devices, supercapacitors have gained significant attention as energy storage devices due to their inherent advantages. However, these inevitably direct contact with blood and trigger coagulation or thrombus formation when implanted in body. In severe cases, negative effects compromise functionality system even jeopardize human health. Herein, a biocompatible electrode material high anticoagulant activity is designed by doping polyaniline macromolecule heparin under neutral conditions, which macromolecules dopants conditions not only avoids toxicity acids biological tissues de‐doping caused small molecules, but also imparts properties material. Based on situ polymerization approach, an all‐in‐one anticoagulation supercapacitor employed manufacture exhibits good electrochemical performance (energy density 18.89 µWh cm −2 power 197.8 µW ), cycling stability (capacitance retention 70.23% after 2, 000 cycles), (APTT 15.47 s, PT 16.57 TT 49.47 FIB 1.12 g L −1 tissue compatibility. The strategy provides valuable reference for supply bioelectronics.
