Research in the near future involves the integration of multi-functional nanodevices into selfcontained nanosystems with capabilities of sensing, controlling, communicating and actuating/responding. A nanosystem is composed not only of nanodevices but also a nanopower-source (or nano-battery). But the small size of the nano-battery significantly limits the battery lifetime. It is highly desirab...

Research applications in biomedical science and technology usually require various portable, wearable, easy-to-use, and/or implantable devices that can interface with biological systems. Organic or hybrid organic–inorganic microelectronics and nanoelectronics have long been a possibility. However, these devices require a power source, such as electrochemical cells or piezoelectric, thermoelectr...
