How to Do Object Detection With ESP32-Cam Using CircuitDigest Cloud This tutorial shows you how to build a real-time object detection system using the ESP32-CAM module and the CircuitDigest Cloud Object Detection API. The system captures an image on button press, sends it to the cloud via wireless or internet connection, retrieves the identified objects with name(s), how many there were and how confident (how much certainty the algorithm has) of the object… |

Tiny Brain Sensor that Fits Between Hair Strands and Lets You Use Tech Hands-Free Researchers at Georgia Tech have come up with a small and flexible brain sensor that can sit just under the skin, between our hair follicles. It is designed to be comfortable enough to wear all day and does not need any wires or gel to work. These sensors are part of what’s called Brain-Computer Interface (BCI) technology. This new sensor uses tiny microneedles to get a better reading… |

Starfish-Inspired AI Heart Monitor Tracks Your Heart with 90% Accuracy Researchers at the University of Missouri have created a new heart monitor that sticks to the body with five arms, just like how a starfish holds onto things with its legs. The team, led by Sicheng Chen and Zheng Yan, designed this wearable heart monitor that is shaped like a starfish. Each of the five arms of the device has built-in sensors that pick up both the electrical and… |
