In the U.S., one in five of the 37 million adults who has diabetes is not aware of it (according to the U.S. CDC – Centers for Disease Control & Prevention). Current methods of diagnosing diabetes and ...

In a recent review article published in the journal Analytical Methods, researchers have been investigating laser-induced graphene (LIG) sensors, with a focus on their fast, eco-friendly fabrication ...

Explore the capabilities of the Neje Master 2S Plus with its powerful A40640 laser module in this exciting video. Watch as I demonstrate how to cut and engrave various materials to build a fantastic ...

This project demonstrates the creation of an Arduino-based non-invasive glucometer. The glucose level is estimated using a trained polynomial regression model based on heart rate (BPM) and oxygen ...

I purchased one of each of these cheap sensors recently from aliexpress for testing purposes. Compared with the ubiquitous HC-SR04 (*), I liked the idea of having a combined emitter/receiver, i.e.

Abstract: This paper reports on a 6-axis force-torque sensor using standing laser-induced graphene (LIG) cantilevers. The proposed sensor consists of eight $\mathbf{3}\times \mathbf{3}\mathbf{mm}$ ...

Abstract: Pipes, which are the main means of transporting resources, deteriorate over time, thereby leading to defects or accidents. Therefore, periodic inspection of pipes is required, and a pipe ...
