Gait sensor predicts senior falls

University of Illinois professors Bruce Schatz and David Buchner have developed a system to predict senior fall risk using motion sensors that measure walking patterns.

67 women over 60 were tested on walking ability,  detailed past annual falls, and wore an accelerometer for one week.

The analysis of device data and reported history enabled the researchers to accurately predict falls based on unsteadiness in standing and walking.

The goal is prevention — encouraging  those who know that they are at risk, and their physicians, to focus on strength and balance exercises.

Sensor assesses blood clotting in 30 minutes

ClotChip assesses  blood clotting 95 times faster than current methods, with a single single drop of blood, using miniaturized dielectric spectroscopy.

A finger-prick sample is taken from heart arrhythmia, pulmonary embolism, post surgery, or  hemophilia patients, to analyze clotting abilities in the ER or at home.  Results are received in 30 minutes.

Caregivers currently cannot quickly assess if a patient with coagulation issues is at risk for spontaneous bleeding, or if the drugs they are taking are effective.

The company is completing clinical trials for use in hemophilia and anticoagulation therapy.

Eye implant measures pressure, releases fluid, in glaucoma

Caltech’s Azita Emami, Aubrey Shapero, Abhinav Agarwal and colleagues have developed a miniaturized, fully wireless, highly-sensitive, implantable, continuous pressure sensor that can remain in the human eye for four years.  The goal is early detection and treatment of glaucoma progression.

Current tonometer measurement, which requires anesthesia, only measures pressure during an appointment, and can miss many daily pressure fluctuations.

The device is implanted on the white of the eye and does not interfere with vision. It consists of a pressure sensor, control circuitry, and an antenna. With no battery, it small and long lasting. Radio waves from a handheld scanner are received by the antenna and generate a small voltage that temporarily powers the device, which then takes a pressure reading and sends the signal back to the reader, using the same antenna.

Encapsulation with liquid silicone and a polymer called parylene allowed the researchers to overcome the impact of fluid corrosion and tissue growth.  This is what enables the implant to remain in the eye much longer than previous devices.

A valve could also be added to release small amounts of fluid as tears, when pressure rises too high, creating a closed-loop glaucoma management system.

Cheap, molecular-wired, metabolite-measuring sensor

Cambridge’s Anna-Maria Pappa, KAUST’s Sahika Inal, and colleagues have developed a low cost, molecular wired sensor that can measure metabolites in sweat, tears, saliva or blood.  It can be incorporated into flexible and stretchable substrates for cellular-level health monitoring.

A synthesised polymer acts as a molecular wire, accepting electrons produced during electrochemical reactions. It merges with sweat, tears or blood, absorbing ions and swelling, leading to high sensitivity.  The signal can be amplified when incorporated into complex circuits, responding to tiny fluctuations in metabolite concentration.

According to Pappa: “This is the first time that it’s been possible to use an electron accepting polymer that can be tailored to improve communication with the enzymes, which allows for the direct detection of a metabolite. It opens up new directions in biosensing, where materials can be designed to interact with a specific metabolite, resulting in far more sensitive and selective sensors.”

“Artificial nerve” system for sensory prosthetics, robots

Stanford’s  Zhenan Bao has developed an artificial sensory nerve system that can activate the twitch reflex in a cockroach and identify letters in the Braille alphabet. Bao describes it as “a step toward making skin-like sensory neural networks for all sorts of applications”  which would include artificial skin that creates a sense of touch in prosthetics.

The artificial nerve circuit integrates three components:

  • A touch sensor that can detect minuscule forces.
  • A flexible electronic neuron which receives signals from the touch sensor.
  • An artificial synaptic transistor modeled after human synapses which is stimulated by theses sensory signals.

The system was successfully tested to generate both reflexes and a sense touch. The team  also hopes to create low-power, artificial sensor nets to cover robots, to provide feedback that makes them more agile.

Body heat-powered, self-repairing health sensor system

Hossam Haick at Technion-Israel Institute of Technology has developed a body heat powered, self-repairing system of sensors for disease detection and monitoring.

Unlike other wearables, the ability to derive energy from the wearer,  and to fix tears and scratches, prevents the need to turn off the device for repair or charging, allowing truly continuous tracking.

Ingestible “bacteria on a chip” detects blood, inflammation

MIT’s Timothy Lu has developed an ingestible sensor with embedded genetically engineered bacteria to  diagnose bleeding or other gastrointestinal issues.

The “bacteria-on-a-chip” approach combines living cell sensors with ultra-low-power electronics that convert the bacterial response into a signal read by a phone.

The technology has only been tested in pigs, but shows promise in detecting gastrointestinal blood and inflammation. The researchers believe that the sensor will be able to be remain in the digestive tract for days or weeks, sending continuous signals.

Cheap, noninvasive patch monitors glucose

UCSD’s Joe Wang‘s needless adhesive glucose monitor has begun a phase I clinical trial.  The small patch measures insulin levels through sweat on the skin, eliminating the need for a skin prick.  The paper – tattoo is printed with two integrated electrodes that apply a small amount of electrical current.  Glucose molecules residing below the skin are forced to rise to the surface, allowing blood sugar to be measured.

Through its SENSOR study,  the team s testing the tattoo-like sensor’s accuracy, compared to a traditional glucometer. The  trial is enrolling 50 adults, ages 18 to 75, with type 1 or 2 diabetes, or diabetes due to other causes. Participants wear a sensor while fasting, and up to 2 hours after eating.

The goal is a cheap, noninvasive, discreet, user friendly glucose monitor that provides continuous measurement.  The sensor currently provides only one readout.
