Visual SLAM: Sensor Application in Autonomous Mobile Robots
Visual SLAM is now a trending approach in autonomous mobile robot development. Mobile robot is the one capable of transporting itself from place to place. For example, the first mobile robot emerged as a ...
Cancer Cell Detection Using a Low-Cost Fluorometer
For women across all socioeconomic groups, breast cancer poses a large threat. Approximately 1 in every 8 women will be diagnosed with the cancer during her lifetime. Additionally, it is one of the leading ...
Diode Lasers for Cytometry: Cell Counting and Sorting
Since the invention of the first operating laser in 1960, lasers have been designed in various regions of the electromagnetic spectrum and output powers. Soon after the advent of semiconductor fabrication ...
IR Sensors: What and How to Choose
An object that has a temperature greater than absolute zero emits some type of radiation. More often than not, objects surrounding us emit radiation in the form of heat that is not visible to the naked ...
Dark Matter: A Brief Overview
When we think about the type of matter that makes up the majority of our universe, we tend to say it is baryonic (stars, gases, galaxies, planets, and dust). While it is true that baryonic matter makes up ...
Gravitational Waves: Distortion of Space-Time Fabric
On September 14, 2016, one of the greatest discoveries in Physics took place: Detection of Gravitational waves. Gravitational waves were theorized on the basis of General Relativity (GR) – a theory ...
Neural Imaging with Visible Light: Advanced Implantable Sensor
Previously, we discussed a technique for producing high resolution maps of neural activity in the brain called Optical Recording of Intrinsic Signal, or ORIS. Conventional methods for performing ORIS ...
Neural Imaging with Visible Light: Implantable Optical Sensors
Previously, we discussed how visible light in combination with implantable optical sensors was used to map epileptic neural activity and localize focal seizures on the surface of the brain. Scientists at ...
Endothelial Surface Layer Imaging: Diagnosing Early Sepsis
A joint team of researchers from the Korea Advanced Institute of Science and Technology and the Seoul National University have achieved in vivo imaging of the endothelial surface layer. The endothelial ...
Dynamic Laparoscopic Graspers For Minimally Invasive Surgery
Developers at Briteseed, a biotechnology company in Illinois, devised a handheld prototype that they say will make it significantly easier for surgeons to locate blood vessels during minimally invasive ...
