Edge computing on a smartphone has been used to analyze data collected by a multimodal flexible wearable sensor patch and detect arrhythmia, coughs and falls.

Researchers from Osaka University investigated the thermal energy changes across nanopores that allow the selective flow of ions. Switching off the flow of ions in one direction led to a cooling effect. The findings have applications in nanofluidic devices and provide insight into the factors governing ion channels in cells. The nanopore material could be tailored to tune the cooling and arrays could be produced to scale up the effect.
