Kinsa Smart Ear Thermometer with Wireless Smartphone Connectivity
Kinsa Inc., maker of the Kinsa smartphone-connected thermometer, will soon be making available its new Kinsa Smart Ear Thermometer.
The in-ear device, designed primarily for pediatric use, automatically syncs up with Kinsa’s app to upload readings and track them over time.
The app makes suggestions to see a doctor and potential causes
if the fever lasts long enough or if the temperature crosses certain
thresholds, and does this with the person’s age andadditional
symptoms in mind.
It will also let you know if there arecertain infections known to be going
around in your area.
Interestingly, the sensor tip doesn’t use covers, supposedly being easy enough to clean.
The device can be used without a smartphone, having its own illuminated display that is easy to see even when taking readings at night.
UCSD Mouth Guard Tracks Levels of Uric Acid Without Blood Draws
The saliva holds a lot of chemical cues about the state of the rest of the human body, so researchers at University of California, San Diego are working on sensor technology that can be integrated into mouth guards to track these cues. In the latest issue of Biosensors and Bioelectronics, the researchers are reporting on a sensor that is able to detect uric acid in saliva with precision similar to the standard blood draws.
The sensor has been integrated into a prototype mouth guard that also contains a battery, additional electronics, and a Bluetooth chip for wirelessly transmitting readings to a smartphone or other device.
So far the team tested the sensor with saliva samples from healthy volunteers, as well as a hyperuricemic patient who was further treated with Allopurinol. The new sensor detected normal levels of uric acid in healthy persons, while the saliva of the patient with high uric acid was validated to be so. Moreover, the sensor was able to detect the dropping of uric acid as the Allopurinol took effect.
The researchers will next move to having people actually wear the mouth guard sensor rather than transferring the saliva onto it, as well as expanding the device’s tracking capabilities to include markers like glucose, lactate, and cortisol.

Modular Add-On Brings Polarized Light Microscopy, Malaria Diagnosis to Smartphones
Researchers at Texas A&M University have developed a novel point-of-care device for field-based diagnosis of malaria using a smartphone. The mobile-optical-polarization imaging device (MOPID) attaches to smartphones or tablets and co-opts the camera to detect birefringent hemozoin in histological samples, which is indicative of malarial infection.
Despite advances in diagnostic approaches and treatment, malaria remains one of the leading sources of disease and death in developing nations. The “gold standard” of detection, evaluation of Giemsa-stained blood smears via bright-field microscopy, often requires skilled technicians and laboratory environments that are few and far between in the regions that are most in need. Even when available for field-testing, white light microscopy tends to report many false positive diagnoses as well. Bench-top polarized light microscopy systems, while more definitive, are large, expensive pieces of equipment that are complex to operate, and to maintain as well.
The MOPID, though, appears to offer a highly-mobile and effective alternative, at a cost that should be palatable in underserved countries. The device in its current form has demonstrated imaging properties that compare favorably with a reference Leica DMLM polarized microscope – a resolution of 1.05 μm, system magnification in the range of 50x, and field of view measuring 0.78 mm x 0.79 mm.
Going forward towards release and dissemination of the technology, the group is currently concentrating on preparing units for in vivo field-testing in Rwanda. To do so, they will be taking efforts to lower the physical profile of the device, improve upon human factors engineering and user-interface components, and lower costs. The ultimate vision is for each MOPID diagnostic test to be priced under $1.00 per result, anywhere in the world.
