Breaking NewsSuperXcaps enable more effective Energy HarvestingPhiladelphia, PA (April 20, 2010) - Energy harvesting calls for collecting light energy from solar or photovoltaic cells, piezoelectric from pressure, kinetic energy from movement, or inductive energy from rotation or motion. This is what generates the low levels of current that make wireless sensors operational. Until recently, however, capturing and storing sufficient power for these applications was a challenge.
OptiXtal SuperXcaps are wafer-thin and ultra-light. The outer shell is made of a metallic membrane and the flexible bendable packets can be configured in a variety of shapes and sizes. Farad capacitances can also be matched to the power requirements of the application. This enables designers to fit them in small, tight spaces which means changing the architecture in a sensor may be unnecessary. Competitive supercapacitors are generally manufactured in a battery-like housing with a battery-like hard shell exterior casing. Clearly this kind of construction will not offer the design flexibility enabled by OptiXtal SuperXcaps SuperXcap supercapacitors can be arranged in series, parallel, or any other design configuration where bridge technology makes sense.

One of our engineers will be glad to discuss the feasibility of including SuperXcaps in your next design. ### For further information contact:
Supercapacitors with lower ESR (Equivalent Series Resistance) ratings introducedPhiladelphia, PA (April 8, 2010) - With ¼ the ESR of many competitive supercapacitors, new OptiXtal, Inc. SuperXcapsTM offer the lowest ESR available. The 5F SuperXcap handles 5 amp maximum current and is rated with an ESR (DC) of 70 mΩ. Typical competitive 5F units offer maximum amps of only 3.4 amp maximum current and an ESR (DC) of 200 mΩ. This means the time constant, (ESR x Capacitance) of the SuperXcap is far lower. By charging (and discharging) a lot faster, performance effectiveness is significantly improved. In fact, if the competitive 5F unit were required to take on the maximum current easily handled by the OptiXtal SuperXcap, it would burn out. Another OptiXtal SuperXcap advantage is the unique housing. Standard supercaps are cylinder-shaped with hard outer shells; SuperXcaps are contained in a flexible ultra-thin pouch. This structural difference means they can be adapted to a variety of end-use applications such as cell phones, battery operated power tools, and wireless energy harvesting devices for capture of motion, light & strain measurement. This lower ESR value is especially important in maximizing the potential of the remaining current in a discharging battery. Once a battery runs down to the point where it can no longer generate sufficient power for start up, an OptiXtal SuperXcap can be called upon to pull the remaining charge from the battery and deliver it with high power burst required at start-up. For energy recapture, peak load shaving, and high power applications, SuperXcaps are the only supercapacitor that meets today's energy harvesting expectations. SuperXcap supercapacitors can be arranged in series, parallel, or any other design configuration where bridge technology makes sense.

The World's First Ultra-thin SupercapacitorMarch 15, 2007 -- OpiXtal, Inc. has developed a new kind of
capacitor, which offers 10x the power of a battery-based energy
source. Instead of being tightly wound and
Given the high demand for battery operated electronics, this new bridge power SuperXcap capacitor could quickly help manufacturers create new or improved battery-powered products that are clearly superior to comparable products offered by the competition. For example, SuperXcap 5F capacitors have almost 5x the power density by weight and are 1.5x more volumetrically efficient than other capacitors. This means they deliver more W/kg., for that extra power new applications could soon require. SuperXcap capacitors are not sensitive to temperature and deliver a constant charge from -40ºC to +50ºC plus users can count on at least 500,000 charge/discharge cycles before changeout may be required. By delivering a burst of instantaneous power at the start of battery-driven devices, the OptiXtal SuperXcap can considerably extend a battery's length of service. Plus the SuperXcap re-charges itself in seconds, so it's always prepared for the next squeeze of the trigger. SuperXcaps can be arranged in series, parallel, or any other design configuration where bridge technology makes sense.

New SuperXcaps from OptiXtal can solve the problem. By expending all acquired energy in a single power burst to
facilitate information transmission or programmed process controls, OptiXtal SuperXcaps will make remote sensors a
lot more functional. SuperXcaps are also far more efficient at converting energy gained from the environment than
systems based on batteries which recharge slowly and lose their charging capabilities after a few hundred cycles.
OptiXtal SuperXcaps recharge in seconds and offer 500,000 charge/discharge cycles before change out is recommended.
That means years of reliable functioning at thousands of sites … often without upkeep or maintenance of any kind.
contained in heavy metal or ceramic
cylinders like other commercially available capacitors, the new
SuperXcapTM capacitors from OptiXtal are thin, light, flexible and
can be easily stacked for added capacitance. SuperXcap capacitors are
rated for 2.7 Volts and come in pouches equivalent to 5 or 25
Farads.
