Researchers develop a stretchable battery powered by air moisture with a built-in self-destruct feature for IoT devices.

Researchers from North Carolina State University and Rice University have created a nontoxic, stretchable battery that operates by extracting moisture from the ambient environment—even in climates as ...

In a Penn State lab, a small cylinder of soil sits wired with sensors, slowly cooling as it mimics conditions thousands of ...

On a miniature roadway made of cardboard and tape, a small grid of LED lights flickers from red to green. It looks like a toy, but for Yash Javhare—who is in his Second Year of Diploma in AI & Machine ...

The PlantGPT prototype is currently being tested on houseplants while the team continues refining the system’s capabilities. Joy Rutledge and Temple Dees are working at Spelman College’s Arthur M.

What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting real-time data on soil moisture, temperature, and sunlight. From sensor calibration ...

Abstract: The calibration process involved comparing data from capacitive sensors with soil moisture content measured continuously by the volumetric water content (VWC) method. The results showed that ...

The SparkFun Ultrasonic Distance Sensor - TCT40 (sen-24805) a user-friendly upgrade to the popular HC-SR04 sensor, offers non-contact distance measurement from 2cm to 400cm with an accuracy of 3mm.

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...
