With the planned proliferation of the Internet-of-Things, billions of power limited wireless sensing devices are expected to be sold worldwide.  Within that group is a large subset of applications in which temperature sensing will be important.  Needed for this application space are ultra-small and ultra-low-power temperature sensors. 

Easy to Wear Dry EEG Sensors for Human–Computer Interactions

Measurements based on electroencephalogram (EEG) are made by placing electrodes over a human scalp to apply and receive electrical signals. Various implementations of EEG sensors are available. The electroencephalogram (EEG) has recently gained popularity for use in various non-clinical studies but still lacks any robust, single application outside well-controlled laboratory environments. As the limitations of EEG are mostly due to the low spatial resolution, using multiple bio-sensing modalities proves to be better performing than EEG alone

A Simple Integrated Device For Assessing Lung Health

Chronic lung diseases, like asthma, impose critical challenges on both the patients and the physicians due to the complexity of the diseases. Not only are these diseases tough to accurately assess, many of the diseases can be impacted by other physical and sociological factors. Perhaps a greater difficulty lies in measuring the effectiveness and compliance of the medications including inhaled medications. The invention discovered at the University of California, Irvine, is an “all-in-one,” portable device that offers complete assessment of lung health. It also incorporates a novel technology for monitoring the effectiveness and compliance of a medication, thereby, providing a personalized treatment and care plan for adults and children with asthma.
