We are excited to have an article in ReadWrite (formerly WearableWorld). In the article Larry Burgess explains the latest options for powering wearable devices. He highlights the quest for the development of smaller, more efficient, and longer-lasting energy sources. He covers battery size, shape, capacity, and reliability for a number of energy source options: Lithium [...]
As the number of wearable devices increases, the demand for smaller and longer-lasting devices, remote transmitters and transponders, and higher device intelligence will drive the quest for higher energy efficiency and capacity in the power sources of these devices. If we don't continuously improve our batteries, the wearable industry will power down. We are excited [...]
The biggest challenge in wireless medical device is battery life: how to maximize the length of time between charges given the anticipated level of use. One big factor is the power need to transmit the required data volume over the desired distance. To maximize battery life given a target form factor we conserve power by [...]
Gone are the days when laptops drive the definition of low-power. Suppliers rely more and more on consultants to provide specific skills needed to design today’s exploding array of battery operated devices including wearable devices, home health, mhealth and implantable devices. The most challenging problem is to support wireless devices with sufficiently long range and [...]
A modern smart phone has upward of a dozen different wireless options, this article explores the best wireless options for communicating with small devices from your smart phone based on the particulars of your application requirements. Overview The proliferation of clever apps for almost anything along with the availability of small, inexpensive radio modules and [...]
With intense deadline pressure to demo a new working system at an upcoming tradeshow, a global manufacturing firm based in China turned to Voler Systems for help. They contacted us 8 weeks before the tradeshow, but like many large organizations, it took four weeks to give us approval to start. They were committed to a [...]
Sometimes it is just fun to look ahead and wonder what the future will bring. In 2011, there have been some interesting announcements that get the imagination going. Epidermal electronics: engineers at the University of Illinois have developed a temporary tattoo-like electronic patch that mounts directly onto the skin. If you can build skin-mounted electronics [...]
Ultracapacitors are well suited to replace batteries in many applications. Voler Systems developed such a replacement for a company that makes RFID and wireless technology products.The battery replacement was cheaper with a longer life than a standard battery.
Ultracapacitors, also referred to as supercapacitors or double-layer capacitors, are electrochemical capacitors that have an unusually high energy density when compared to common capacitors. Conventional capacitors have enormous power but store only tiny amounts of energy. Ultracapacitors offer orders of magnitude higher energy storage. Larger ultracapacitors have capacities up to 5,000 Farads as of 2010, and 10 Farad capacitors cost only a few dollars.
