Smart Sweatband Senses Dehydration

It’s not easy to tell if you’re dehydrated. Nearly 75 percent of Americans are chronically dehydrated, putting many people at a health risk.

Now, a smart sweatband could tell you when you exercise is bordering on dangerous. By measuring the chemicals in your sweat, this sensor can alert you of dangerous situations by linking to your smartphone in the first fully integrated electronic system that can provide continuous, noninvasive monitoring of multiple biochemical in perspiration.

The device has the potential to measure more than perspiration, with goals of preforming population-level studies for medical applications.

Ways to Get ECS Article Credits

In 2015 ECS published just over 700 Open Access papers. This was fantastic news for ECS’s mission to Free the Science, and even better news for our authors as 96% of those papers were published as OA at no charge.Open Access Logo

Why were we giving away so many article credits? When ECS first launched our Author Choice Open Access program in February 2014, we wanted to explore the feasibility – both financially and practically – of supporting OA as far as we could in our publications.

It quickly became obvious how eager our community was to assist in ECS’s commitment to disseminate our research as widely as possible. In another commitment to our libraries, though, we had promised not to increase subscription prices, and have stuck by that commitment since 2013.

Moving into 2016, we wanted to continue to offer Article Credits to as many authors as possible, but also needed to ensure that our publications are self-sustaining. In order to accomplish this, we launched a new product called: ECS Plus. This offers libraries a subscription to all of our content PLUS unlimited Article Credits for authors affiliated with their institutions.

I wanted to use this blog post as an opportunity to remind authors interested in publishing Open Access to take advantage of the many ways you can publish OA with ECS for free, or at a very reduced cost:

  • Our new product, ECS Plus, is exceptionally competitively priced and includes a complete subscription to ECS’s Digital Library, as well as unlimited article credits for affiliated authors. Please encourage your librarians if this is something that you or your colleagues value!
  • ECS Members receive 1 free article credit per year – if you’re not yet a member, it might be time to consider joining us. Find out about becoming an ECS member, and other benefits of joining, by checking out our new membership page!
  • Once an ECS Member’s article credit has been used, any subsequent OA publications receive a 75% discount – that’s $600 off our already low APCs.

If you have any questions about changes to our Author Choice Open Access program, you can find out more on our information pages about OA, ECS Plus, and on our subscription information pages – or you can get in touch with us directly at oa@electrochem.org.

ECS’s goal is to make Open Access publishing free for all our authors. To help make this a reality please give to the Free the Science Fund.

Uphill Battle for Electric Cars

With plunging oil prices, it is proving to be more difficult than ever to entice buyers into purchasing an electric vehicle. While the low oil prices may be good for consumers’ gas tanks, the transportation sector continues to account for 27 percent of the United States’ greenhouse gas emissions.

The question then arises of how electric car manufacturers can steer folks back toward electric vehicles and away from gas-guzzling cars?

Impact of falling oil prices

“It definitely makes the transition to sustainable energy more difficult,” said Elon Musk, Tesla CEO, at a business conference in Hong Kong about the impact of the free-falling oil prices.

Tesla rose to prominence in 2003 when oil prices soared, making electric vehicles all the more tempting. With oil prices continually on the decline, it’s now up to companies like Tesla to compel buyers and stress the importance of transitioning toward cleaner vehicles.

New features for electric cars

For companies like Tesla, that means developing things like autonomous cars with “summon” features – allowing the user to call their car just like a pet. Even aesthetic aspects have become more important, with Tesla focusing on futuristic designs.

“What we’re aspiring to do is to make the cars so compelling that even with lower gas prices, it’s still the car you want to buy,” Musk said.

Car sensor technology

Is your Uber driver going too fast? Soon, you’ll be able to prove it.

Since 2009, Uber has taken off all around the world as the premier ride-sharing company. Now, your Uber experience may improve thanks to the company’s application of sensor technology via each driver’s smartphone.

A typical Uber experience asks the driver and passenger to rate each other after each drive. If the mark comes in unusually low, Uber can now investigate your claims by examining the driver’s journey with data pertaining to speed and erratic driving. The company aims to collect this data from the gyrometer in the driver’s phone and data from GPS and accelerometers.

This from Uber:

Gyrometers in phones can measure small movements, while GPS and accelerometers show how often a vehicle starts and stops, as well as its overall speed. If a rider complains that a driver accelerated too fast and broke too hard, we can review that trip using data. If the feedback is accurate, then we can get in touch with the driver.

Read the full article.

An array of different sensory devices are used in your smartphone, allowing our phones to follow our commands and functions seamlessly. From the sensors in your screen that recognize touch to the voltage and current measurement sensors for battery utilization optimization, sensors are constantly responding to the ever-increasing demand for faster, cheaper, smaller, and more sensitive means to monitor the world around us.

Now these sensor technologies could help produce safer conditions on the road. If gyrometer results show that drivers are moving their phones while driving, Uber may offer mounts. If the accelerators pick up constant speeding conditions, Uber is ready to tell their drivers to curb their enthusiasm.

Importance of Energy Storage

While society as a whole is moving toward cleaner, more renewable energy sources, there is one key component that is typically glossed over in the energy technology conversation: energy storage.

Developments in solar and wind are critical in the battle against climate change, but without advances in energy storage, our efforts may fall short. What happens when the sun isn’t shining or the wind isn’t blowing?

The folks at Popular Science are providing a friendly analogy to explain the the importance of energy storage.

Graphene, better known as the wonder material, has seemingly limitless possibilities. From fuel cells to night-vision to hearing, there aren’t many areas that graphene hasn’t touched. Now, researchers from Rice University and transforming graphene for uses in air travel safety.

James Tour, past ECS lecturer and molecular electronics pioneer, has led a team in developing a thin coating of graphene nanoribbons to act as a real-time de-icer for aircrafts, wind turbines, and other surfaces exposed to winter weather.

Through electrothermal heat, the graphene nanoribbons melted centimeter-thick ice on a static helicopter rotor blade in a -4° Fahrenheit environment.

This from Rice University:

The nanoribbons produced commercially by unzipping nanotubes, a process also invented at Rice, are highly conductive. Rather than trying to produce large sheets of expensive graphene, the lab determined years ago that nanoribbons in composites would interconnect and conduct electricity across the material with much lower loadings than traditionally needed.

“Applying this composite to wings could save time and money at airports where the glycol-based chemicals now used to de-ice aircraft are also an environmental concern,” Tour said.

The coating may also protect aircrafts from lightning strikes and provide and extra layer of electromagnetic shielding.

Advancing Lithium-Air Batteries

As electronics advances, the demand for high-performance batteries increases. The lithium-ion battery is currently leading the charge in powering portable electronic devices, but another lithium-based battery contender is on the horizon.

The lithium-air battery is one of the most promising research areas in current lithium-based battery technology. While researchers such as ECS’s K.M. Abraham have been on the Li-air beat since the late 90s, current research is looking to propel this technology with the hopes of commercializing it for practical use.

A new contender: Lithium-air batteries

Recently, Khalil Amine, IMLB chair; and Larry Curtiss, IMLB invited speaker, co-authored a paper detailing a lithium-air battery that could store up to five times more energy than today’s lithium-ion battery.
