Researchers at the University of Colorado Boulder have created a new way to build and control tiny particles that can move ...

In this paper, a miniaturized fluxgate sensor with high sensitivity is presented by increasing the permeability of the magnetic material. The fluxgate sensor is composed of a rectangular-ring shaped ...

Surface acoustic wave (SAW) micro-pressure sensor, which is a microelectronic integrated sensor, has important research significance for measuring microclearance pressure. In this paper, a coupling ...

Put simply, the Sigma 56mm F1.4 is the best second lens you can buy in this format, especially for portraiture. Being a Sigma ...

Understanding pH sensors pH sensors typically consist of a glass electrode that produces a voltage proportional to the hydrogen ion activity (pH level) in a solution. This voltage signal then needs to ...

To develop in vivo monitoring meter for pH measurements is still the bottleneck for understanding the role of pH plays in the brain diseases. In this work, a selective and sensitive electrochemical pH ...

Researchers at BITS Pilani, Hyderabad, have created a low-cost biosensor for rapid metabolite detection in bodily fluids, costing just Rs 15. This needle-free device monitors glucose and lactate ...

We have developed a simple-to-manufacture microfabricated gas preconcentrator for MEMS-based chemical sensing applications. Cavities and microfluidic channels were created using a wet etch process ...

SwitchBot's water sensor is very affordable and extra-easy to set up with no hub required and very little app work necessary. I still have mine set up under the kitchen sink, in fact.
