Non-toxic printed supercapacitors operating in sub-zero conditions

Printed Supercapacitors for Energy Harvesting Applications

Energy harvesting from ambient sources such as light or vibrations is a promising method for powering distributed and ubiquitous electronics. Harvesting requires an intermediate energy storage, for which supercapacitors are well suited due to their long cycle life compared to batteries. Moreover, supercapacitors can be prepared from non-toxic materials with printing methods, enabling their use ...

DNA hydrogel-based supercapacitors operating in physiological fluids

DNA nanostructures have been attractive due to their structural properties resulting in many important breakthroughs especially in controlled assemblies and many biological applications. Here, we report a unique energy storage device which is a supercapacitor that uses nanostructured DNA hydrogel (Dgel) as a template and layer-by-layer (LBL)-deposited polyelectrolyte multilayers (PEMs) as condu...

Towards Extending Sensor Node Lifetime with Printed Supercapacitors

The realization of completely autonomous wireless sensor networks (WSN) has been hindered with difficulties in implementing a truly “perpetual” power supply. Typically, the generic power supply for a sensor node is a battery, which is limited in cycle life. Current research in energy scavenging technology, along with the use of innovative energy storage devices such as supercapacitors, has demo...

Sub-linear Size Pairing-based Non-interactive Zero-Knowledge Arguments

We construct non-interactive zero-knowledge arguments for circuit satisfiability and arithmetic circuits with perfect completeness, perfect zero-knowledge and computational (co-)soundness. The non-interactive zeroknowledge arguments have sub-linear size and very efficient public verification. Our construction uses bilinear groups and is only proven secure in the generic group model, but does no...
