mPhase Technologies, Inc. is a U.S. based microfluidic and nanotechnology specialist. Through its wholly owned subsidiary Always Ready Inc., mPhase is commercializing its first nanotechnology product, the Smart NanoBattery.
The Smart NanoBattery offers novel functionality not usually seen in a battery, namely a shelf life of years, the ability to manage power in new ways, and a more environmentally friendly disposal option. This solution and other innovations from the field of nanotechnology will be presented to the interested specialist public at the sixth NanoEurope, which will be held in St. Gallen (Switzerland) on September 16 - 17, 2008.
One of the most important components restricting the performance and maintenance of wireless sensor systems is the battery required for powering the sensors. mPhase/AlwaysReady, a company headquartered in New Jersey, is commercializing scientific findings from the field of microfluidics and nanotechnology. mPhase/AlwaysReady has developed a novel battery geared for sensor systems which will boost innovation initially in defense applications and later on also in commercial uses.
A smart battery based on a unique architecture
The nanobattery developed by mPhase/AlwaysReady utilizes knowledge from nanotechnology and microfluidics. It makes use of a unique membrane whose nanostructured surface is extremely water-repellent. This enables a liquid electrolyte to be kept separate from the battery's electrode until energy is required. This allows the battery to be stored for an unlimited period of time before being used.
In addition, the battery is equipped with cells which can be individually activated for only those moments in which energy is needed. This is not possible in conventional batteries, where the chemical reaction cannot be interrupted until the battery has been entirely depleted. This energy on demand property gives the nanobattery a long, useful life and makes it the ideal choice for wireless light-current sensor systems.
Broad range of battery applications is conceivable
The Smart NanoBattery opens up new possibilities in the areas of energy storage and management. Initial concrete applications satisfy defense requirements. In the future, this technology may also be integrated in portable electronic devices.
Smart surfaces enable other applications
The unique nanostructured membrane can also be designed to function as a smart surface that can filter liquids. This ability opens up the potential to use the membrane design for applications such as water purification and desalination, as well as self-cleaning glass.
