A research team at the Korea Advanced Institute of Science and Technology (KAIST) has developed tattoo ink made of liquid metal and carbon nanotubes that can work as a bioelectrode. This technology could translate to a tattoo that can function as a health-monitoring device.

Medtronic plc inked an agreement to combine its patient care technologies with a wearable, remote monitoring platform developed by Pasadena, Calif.-based Rockley Photonics Inc. The Bioptx contains compact, photonics-based sensors inside a wristband to monitor a range of biomarkers beyond standard blood pressure, heart rate, pulse oximetry and glucose levels, making Rockley and Medtronic’s development partnership, said Rockley Chair and CEO Andrew Rickman, “a terrific match.”

The FDA granted Adherium Ltd. 510(k) clearance for its next-generation Hailie sensor that connects with Glaxosmithkline plc’s Ellipta inhaler to enable monitoring of medication use for asthma and chronic obstructive pulmonary disorder (COPD).

The Persona IQ combines a knee implant created by Zimmer Biomet Inc. with sensor technology developed by Canary Medical Inc. to capture performance data on range of motion, walking speed, step count and other orthopedic metrics. Liane Teplitsky, Zimmer Biomet’s president of global robotics likens the Persona IQ to a cardiac pacemaker, in this instance collecting important data on the knee implant so doctors working remotely can better understand how the device is performing post-surgery.

Biobeat Technologies Ltd. reported its remote patient monitoring system received FDA clearance to monitor respiratory rate and body temperature. The wireless chest and wrist monitoring device is already cleared for cuffless blood pressure monitoring, blood oxygen saturation and pulse rate. The artificial intelligence platform utilizes a photoplethysmography-based sensor at the surface of the skin that measures volumetric variations of blood circulation.

University of California San Diego engineers have developed tiny 2D sensors that pop up to become a 3D assemblage of microscopic sensors for directly measuring the movement and speed of electrical signals inside the heart. According to nanoengineering professor Sheng Xu, the nanotechnology has enormous implications for heart doctors anxious to better diagnose and treat arrhythmia, heart attack and other diseases.

Investors including SOSV, Cultivate(MD), Wavemaker360 Health, Blu Venture Investors and Broad Street Angels are backing Strados Labs LLC with $4.5 million. The pre-series A funding will be used to accelerate development of the company’s smart sensor platform Resp. The funding comes after Strados received FDA clearance for the product in December 2021 and brings its total raised to $7 million.

PARIS – Researchers at the Institute for Surface Technologies and Photonics in Weiz, Austria, and the Institute of Scientific and Industrial Research Osaka University, Japan, have invented new ultra-flexible health monitoring patches that use harvested bio-mechanical energy. “These new devices represent a wireless e-health patch for accurate pulse and blood pressure monitoring,” Andreas Petritz, from the Institute for Surface Technologies and Photonics (the materials research unit of Joanneum Research FmbH), told BioWorld.

The Tokyo University of Science (TUS) has developed a self-powered diaper biosensor that can monitor urine sugar levels, which could be a boon for both diabetic patients and their caregivers. Caregivers at nursing homes currently open patients’ diapers every few hours to check for urination, thus increasing the caregivers’ workload. The psychological impact on the patient is also increased, for example when their sleep is disturbed.
