Sweat, which contains a wide range of biochemical markers, can tell us a lot about our health. Variations in sweat pH (i.e. acidity or alkalinity), for instance, can tell us whether our body is ...

(Nanowerk Spotlight) Inside a wound, a complex chemical battle unfolds. As healing progresses, the wound environment shifts between acidic and basic states, each change signaling different stages of ...

The inside of a living cell is a surprising patchwork of environments. For example, pH levels can vary dramatically in different organelles, despite them being just a couple hundred nanometers apart.

In a recent study published in Scientific Advances, researchers created a bioresorbable, cordless, passive sensor that monitors pH locally and detects stomach leakage early on. Study: Bioresorbable, ...

The circuit shown in Figure 1 is a completely isolated low power pH sensor signal conditioner and digitizer with automatic temperature compensation for high accuracy. The circuit gives 0.5% accurate ...

To ensure accuracy, we had our garden soil’s pH levels professionally lab tested. We then used each pH meter and compared its results with the lab readings. We also evaluated for ease of use, value, ...
