Script’s app lets parents digitally sign school permission slips, pay for field trips

 Schools are often late to taking advantage of new technologies, so today still do much of their business over paper forms. One pain point in particular – for school administrators, teachers and parents alike – is handling permission forms for activities and field trips. A young startup called Script aims to help. Schools can use Script’s app to manage the entire trip… Read More

AI is giving the entire medical field super powers


The field of medicine has, arguably, been more positively affected by modern deep learning techniques than any other industry. And, despite the unending deluge of panic-ridden articles declaring AI the path to apocalypse, we’re now living in a world where algorithms save lives every day. Welcome to Utopia. Thanks to AI, an iPhone can detect cancer and a smart watch can detect a stroke. Machine learning is infiltrating and optimizing nearly every aspect of medicine from the way 911 emergency services are dispatched to assisting doctors during surgery. You can even quit smoking or kick your opiate addiction with the…

‘Run Gun Sports’ is a Track and Field Game Where Your Legs are Guns, Coming this Thursday

Perusing our Upcoming Games Forum, I was instantly sold on a game called Run Gun Sports when it described itself as a track and field game but your legs are guns. I feel like pretty much any game that involves a description that includes “…but your legs are guns” is an instant winner in my book. I mean, Downwell [$ 2.99] anyone? As for the game itself, it looks just as silly as that premise sounds. You’ll compete in some typical track and field events but with the benefit of being able to fire bullets out of your feet. The blast from those bullets can actually help propel you through the air making for some truly superhuman acrobatic feats. Check out the trailer for Run Gun Sports to see what I mean.

Did I mention that your legs are guns? Run Gun Sports will feature several types of events including hurdles, high jump, horizontal bars, and long jump, and more than 90 different levels with even more already planned for future updates. You’ll be able to represent the flag of your own country in competitions across the world in cities like Barcelona, Atlanta, and Athens that have affiliations with that one major international sporting competition that happens every 4 years and whose name currently escapes me. You’ll also be able to get sponsored by the most well-known sporting brands including “BEEROOK and PURRMA.” And of course, Run Gun Sports will include multiple types of guns for your legs including things like a bazooka, shotgun, and flame thrower, each with their own unique effects. Truly this is a special time to be alive so look for Run Gun Sports when it launches later this week.

Scientists at TU Vienna develop tiny electric field sensor

An electric field sensor based on silicon

Researchers at the Technology University of Vienna have developed a sensor capable of measuring electric fields that is a fraction of the size of comparable devices. 

The ability to measure electric fields with accuracy is vital for industrial applications in manufacturing, weather forecasting and the maintenance of electricity infrastructure.

Now, researchers at the Technology University of Vienna (TU Wien) have developed a silicon-based sensor that acts as a microelectromechanical system. Unlike many conventional measuring devices currently in use, it is able to measure electric fields without distorting them.

The device has been developed with the help of the Department for Integrated Sensor Systems at Danube University Krems. A paper detailing the new concept has been published in the electronics journal Nature Electronics.

Measuring electric fields without distortion

Current methods for measuring electric fields can be inaccurate and clunky. “The equipment currently used to measure electric field strength has some significant downsides,” said Andreas Kainz from the Institute of Sensor and Actuator Systems at TU Wein.

“These devices contain parts that become electrically charged. Conductive metallic components can significantly alter the field being measured; an effect that becomes even more pronounced if the device also has to be grounded to provide a reference point for the measurement.”

Another drawback is size. Traditional equipment tends to be both impractical and difficult to take from one place to another. The TU Wein alternative appears to counter both of those issues.

Being made from silicon avoids interfering with the field it’s attempting to measure. Its small size makes it easy to transport, tiny enough to fit into wearables and promises to simplify the measuring process.

Silicon structures

The device works by utilizing small, grid-shaped silicon structures that are just a few micrometres in diameter. These are fixed onto a small spring. When the silicon is exposed to an electric field, a force is exerted on the silicon crystals, causing the spring to compress or extend.

Another grid – this one fixed – is located above the silicon grid and is lined up with such precision that the grid openings on one grid are entirely covered by the other. So, if an electric field is present, the silicon grid will move out of alignment and cause light to pass through the gaps.

The strength of the electric field is calculated from the amount of light escaping by using “an appropriate calibrated device”.

Tiny silicon sensor brings precision

The new silicon sensor is designed to measure the strength of an electric field rather than its direction. It’s precise enough to measure fields of a relatively low frequency of up to one kilohertz.

“Using our prototype, we have been able to reliably measure weak fields of less than 200 volts per metre,” said Kainz. “This means our system is already performing at roughly the same level as existing products, even though it is significantly smaller and much simpler.”

“Other methods of measurement are already mature approaches – we are just starting out. In future,” he said, “it will certainly be possible to achieve even significantly better results with our microelectromechanical sensor.”
