Wrist wearable measures blood counts, bacteria, air particles

Rutgers scientists Mehdi Javanmard and Abbas Furniturewalla have developed a wrist wearable that can count particles, including blood cells, bacteria, and organic or inorganic air particles. Red blood cell counts can indicate internal bleeding. High or low white blood cell counts can indicate cancers, such as leukemia, or other illnesses.

The plastic wristband includes a flexible circuit board and a thin biosensor with a channel, or pipe, with embedded gold electrodes. A circuit processes electrical signals, and a micro-controller digitizes data, which is transmitted via bluetooth. Blood samples are obtained through pinpricks, and fed through the channel, where the cells counted.

The goal is rapid blood test results with out  lab-based equipment.

Hydrogen peroxide sensor to determine effective chemotherapy

MIT’s Hadley Sikes has developed a sensor that determines whether cancer cells respond to a particular type of chemotherapy by detecting hydrogen peroxide inside human cells.

The technology could help identify new cancer drugs that boost levels of hydrogen peroxide, which induces programmed cell death. The sensors could also be adapted to screen individual patients’ tumors to predict whether such drugs would be effective against them.

Wearable sweat sensor measures cortisol levels

Stanford’s Alberto Salleo has created a  patch that continuously monitors cortisol levels in sweat.  Potential uses include sports performance measurement, early disease detection, adrenal and pituitary gland monitoring, and evaluating the emotional state of young or non verbal patients.

Cortisol influences emotional stress, blood pressure, metabolism, immune response and and memory formation.

The stretchy, rectangular sensor is wrapped around a membrane that specifically binds only to cortisol. It absorbs sweat through holes in the bottom. Sweat pools in a reservoir, topped by the cortisol-sensitive membrane. Charged ions pass through the membrane unless they are blocked by cortisol. The sensor detects the backed up charged ions. The top  waterproof layer protects the patch from contamination.

Wearable acoustic sensors track fetal cardiac activity, skeletal development

Acoustic sensors are increasingly used in monitoring fetal health.

Imperial College’s Niamh Nowlan is using low cost, non-transmitting accelerometers and acoustic sensors to continuously track fetal movement to understand skeletal development. Acoustic sensors enable discrimination between the movement of the fetus and mother.

Israel’s Nuvo Group is continuously monitoring fetal cardiac activity using acoustic sensors and ECG (to track both sound and electrical activity) in a wearable baby belt.

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.”
