Contact-free blood pressure, heart and breath rate monitoring
Cornell’s Edwin Kan has developed a contact-free vital sign monitor using radio-frequency signals and microchip tags. Blood pressure, heart rate and breath rate are measured when radio waves bounce off the body and internal organs, and are detected by an electronic reader from a location anywhere in the room. 200 people can be monitored simultaneously. According…

Single phone sensor tracks heart rate, HR variability, BP, oxygen saturation, ECG, PPG
Sensio by MediaTek is a biosensor that monitors heart rate, heart rate variability, blood pressure, peripheral oxygen saturation levels, ECG and PPG, from a smartphone, in 60 seconds. This could allow continuous monitoring with out multiple sensors. LEDs and a light sensitive sensor measure the absorption of red and infrared light from a user’s fingertips.…

Robots visualize actions, plan, with out human instruction
Sergey Levine and UC Berkeley colleagues have developed robotic learning technology that enables robots to visualize how different behaviors will affect the world around them, with out human instruction. This ability to plan, in various scenarios, could improve self-driving cars and robotic home assistants. Visual foresight allows robots to predict what their cameras will see if they perform…

Glucose-monitoring smartphone case
GPhone, developed by UCSD’s Joe Wang and Patrick Mercier, is a smartphone case and accompanying app that records and tracks glucose readings. It is 3D-printed and has a permanent, reusable sensor on its corner. Enzyme pellets magnetically attach to the sensor, and are stored in a 3D stylus on the side. Users dispense a pellet…

Tiny sensor analyzes biomarkers in sweat
EPFL’s Adrian Ionescu has developed a miniature chip that analyzes biomarkers in sweat to understand a wearer’s health. It is the basis of a modular system that can measure sodium and potassium concentrations (that signal dehydration); body temperature and pH (to detect bacteria and risk factors for other illnesses); chlorine levels (as an early indication of…

3D coronary artery model analyzes impact of blockages
HeartFlow FFR uses data from a CT scan to create a 3D model of the coronary arteries and analyze the impact that blockages have on heart flow, to determine whether a stent is necessary. It replaces a test that uses direct measurement with an instrument inserted into the heart. Standard practice is to push a…

FDA approved EKG band monitors heart activity via Apple Watch
AliveCor’s Kardia EKG band is the first medical accessory to receive FDA approval for use with the Apple Watch. Unlike the optical-based sensor built into the Apple Watch, EKG is considered the most accurate way to record heart activity. AliveCor claims that Kardia is a medical grade heart rate monitor that can identify abnormal heart rhythms…

Vibrating sensors could detect TBI, disease, infection in drop of blood
Purdue’s Jeffrey Rhoads, George Chiu, and Eric Nauman have developed a method to identify biological markers in small amounts of blood that they believe can detect diseases and infections and conditions such as traumatic brain injury at an early stage. An array of sensors enable statistical-based detection The small, cheap vibrating sensors use a piezoelectrically actuated resonant microsystem to…

Small, foam hearable captures heart data
In a small study, Danilo Mandic from Imperial College London has shown that his hearable can be used to capture heart data. The device detected heart pulse by sensing the dilation and constriction of tiny blood vessels in the ear canal, using the mechanical part of the electro-mechanical sensor. The hearable is made of foam and…

Closed-loop control of drug delivery across the blood brain barrier
Tao Sun, Nathan McDannold, Eric Miller and Brigham & Women’s and Tufts colleagues have developed a controller that offers a finer degree of control in penetrating the blood brain barrier for drug delivery. The technology, only tested in rats, could improve safety in humans if found effective. Using focused ultrasound and microbubbles as before, the team…
