A new type of pressure sensors with extremely high sensitivity is introduced. Unlike piezoresistive, capacitive, and linear-variable-differential-transformer-based pressure sensors, the new sensor is ...

This paper presents a resonant pressure micro sensor with a stress isolation layer. This sensor consisted of a glass cap for hermetic package, an SOI layer as sensing elements and a glass base for ...

Despite high theoretical sensitivity, low-cost manufacture, and compactness potentially amenable to lab-on-a-chip use, practical hurdles have stymied the application of the quartz crystal microbalance ...

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 ...
