Researchers at the University of Washington have developed a wireless battery powered sensor that can be attached to a bee's back. The sensor logs temperature and humidity as the bee flies, and the battery is wirelessly recharged when the bee returns to the hive.
[A]fter the bees have finished their day of foraging, they return to their hive where the backpack can upload any data it collected via a method called backscatter, through which a device can share information by reflecting radio waves transmitted from a nearby antenna.
Right now the backpacks can only store about 30 kilobytes of data, so they are limited to carrying sensors that create small amounts of data. Also, the backpacks can upload data only when the bees return to the hive. The team would eventually like to develop backpacks with cameras that can livestream information about plant health back to farmers.
“Having insects carry these sensor systems could be beneficial for farms because bees can sense things that electronic objects, like drones, cannot,” Gollakota said. “With a drone, you’re just flying around randomly, while a bee is going to be drawn to specific things, like the plants it prefers to pollinate. And on top of learning about the environment, you can also learn a lot about how the bees behave.”

• ‘Fronton’ is the FSB’s IoT botnet project
Researchers at Carnegie Mellon have come up with this new IoT Assistant app (available for both iOS and Android) that will supposedly inform you about what Internet-connected smart devices are around you at any point in time, and what kind of information they might be collecting. “Because of new laws like the General Data Protection Regulation (GDPR) […]
MIT researchers outfitted a baby diaper with an RFID tag that emits a wireless signal when the surrounding material gets wet. The wetness “sensor” is actually a type of hydrogel that’s commonly found in diapers to absorb liquid. As the hydrogel gets wet, it swells and its conductivity increases, triggering the RFID tag. The RFID […]
Back in the 50s and 60s, it was no big deal in most areas to make a call to your local liquor store and have beer, wine and spirits delivered right to your house with little to no restriction. However, that ease and simplicity certainly isn’t in place today. Alcohol delivery laws in 2020 are […]
Unless you’re a regular cannabis user, you might be surprised to learn that the plant itself is basically just that — a plant. It’s not until you put cannabis under high heat that the process of decarboxylation breaks down that raw form into the psychoactive compounds that can actually benefit the body. This unlocking process […]
With our smartphones serving as the vital tether that links us to the rest of our lives, it’s no wonder how low batteries and power emergencies can occasionally feel like a life-and-death situation. I mean, it’s usually not, of course…but darned if it doesn’t feel that way when your indicator is showing only 5 percent […]
