New sensor may pave the way in which for urine-analyzing diapers


Urine evaluation could certainly be a precious supply of data on a affected person’s well being, however arranging for samples to be taken and analyzed might be time-consuming. A brand new sensor may assist, by permitting diapers to do the job on an ongoing foundation.

The know-how is being developed by Xi Xie and Hui-Jiun Chen, each from China’s Sun Yat-Sen University.

It’s a versatile system that is concerning the measurement of a US quarter, and it incorporates an array of 5 totally different electrodes – these are linked to a circuit board geared up with a Bluetooth module and a lithium-ion battery. The electrodes are respectively capable of detect potassium ions, sodium ions, hydrogen peroxide, uric acid and glucose, all of that are biomarkers related to varied situations.

When the sensor was examined on urine samples obtained from three volunteers, it was discovered to carry out on the identical commonplace as a conventional industrial evaluation system. Paper take a look at strips, that are one other various, weren’t as delicate.

The array continued to operate nicely when it was built-in into an grownup diaper, to which urine was added. The scientists imagine that in a real-world state of affairs – whereby a diaper would begin out dry then progressively get saturated – the sensor must take a number of readings to be able to collect correct knowledge.

That stated, the info may then be immediately accessed just by holding a Bluetooth-connected smartphone or pill beside the affected person’s mattress. No urine assortment or lab evaluation could be essential.

A paper on the analysis was not too long ago revealed within the journal ACS Applied Nano Materials.
