Wi-Fi Devices as Physical Object Sensors

Posted on by

The new 802.11bf standard will turn Wi-Fi devices into object sensors:

In three years or so, the Wi-Fi specification is scheduled to get an upgrade that will turn wireless devices into sensors capable of gathering data about the people and objects bathed in their signals.

“When 802.11bf will be finalized and introduced as an IEEE standard in September 2024, Wi-Fi will cease to be a communication-only standard and will legitimately become a full-fledged sensing paradigm,” explains Francesco Restuccia, assistant professor of electrical and computer engineering at Northeastern University, in …

Biohybrid robot wired to “hear” using locust’s ear

Posted on by

Researchers at Tel Aviv University have managed to create a kind of cyborg, by integrating the ear of a locust into a robot. The robot was then able to respond to noises that the biological sensor picked up, which could pave the way for more sensitive … Continue reading Biohybrid robot wired to “hear” using locust’s ear→

Practical Sensors: The Many Ways We Measure Heat Electronically

Posted on by

Measuring temperature turns out to be a fundamental function for a huge number of devices. You furnace’s programmable thermostat and digital clocks are obvious examples. If you just needed to know if a certain temperature is exceeded, you could use …read more

“Smellicopter” drone uses live moth antenna to sniff out targets

Posted on by

No matter how good we humans have made something, chances are nature did it better millions of years ago. Rather than compete, it’s often better to tap into the natural version – and that’s exactly what scientists have done with the Smellicopter, a dro… Continue reading “Smellicopter” drone uses live moth antenna to sniff out targets→

Amazon announces a bunch of products aimed at industrial sector

Posted on by

One of the areas that is often left behind when it comes to cloud computing is the industrial sector. That’s because these facilities often have older equipment or proprietary systems that aren’t well suited to the cloud. Amazon wants to change that, and today the company announced a slew of new services at AWS re:Invent […] Continue reading Amazon announces a bunch of products aimed at industrial sector→

“Smart fabric” strain sensor combines strength and sensitivity

Posted on by

In order to monitor their wearers’ movements, smart fabrics typically incorporate strain-measuring sensors. And while such sensors are often impractically fragile, Harvard University scientists have created a new one that can really take a beating.Cont… Continue reading “Smart fabric” strain sensor combines strength and sensitivity→

Implantable gas sensor designed to dissolve when its job is done

Posted on by

While we have been hearing about the development of health-monitoring implantable sensors, most such devices would have to be surgically removed once no longer needed. An experimental new one, however, would just harmlessly dissolve.Continue ReadingCat… Continue reading Implantable gas sensor designed to dissolve when its job is done→
