Art Medical's smart tubes to collect patient data, reduce complications

Backed by $28 million in investment, Israeli biotech company Art Medical, which detects and prevents life-threatening complications in intensive care units, is introducing a new platform that collects comprehensive patient data using sensor-based smart tubes, which will be utilized to reduce the risk of medical complications.

The smart tube technology uses sensors to collect data, and adjusts itself to a patient’s individual needs as they arise.

Oftentimes patients in ICUs become well-accustomed to tubes: breathing tubes, feeding tubes and urine catheters among them. But to date there’s no effective way to determine whether they’re experiencing complications in real time. Nurses and doctors are required to constantly monitor patients in order to identify these events and minimize their complications, but that’s done manually, and can easily overlook time-sensitive events that can lead to complications, or even death.

What are common RF noise sources?

In response to the Federal Communications Commission’s inquiry on whether it should study changes in the radio frequency noise floor, a number of commenters identified common sources of RF noise and interference that they encounter. The most common RF noise sources include:

Harmful LED lamp interference. “The solution in most cases is to replace the lamp with a different brand that does not cause harmful interference. … The bottom line is that the interference is strong enough to affect a 700/800 MHz cellular base station,” said Pericle Engineering in its FCC comment.

Large [electronic]display signs. “Two examples are the Fashion Show Mall on the Las Vegas Strip and several gambling casinos in Black Hawk, CO,” said Pericle. “The culprits here are the switching DC power supplies powering the LED lamps. Because these signs have large metal backings, they act as a reflector and focus the interfering power in one direction. At 800 MHz, harmful interference has been measured to cell sites within 100 feet of display signs while at VHF, harmful interference was measured as far as 900 feet from display signs.”

Nanusens solves MEMS inertial sensor stiction problem


Nanusens, the three year-old Barcelona sensor company, says its CMOS nano-sensor technology has solved the problem of stiction in MEMS inertial sensors.

“Our first silicon nano-sensor samples from GLOBALFOUNDRIES exceeded our expectations showing outstanding resilience to stiction, with the devices going through more than 10,000 switching cycles, each equivalent to more than 1000G shocks,” says Nanusens’ CEO, Dr Josep MontanyĆ  i Silvestre. “and the sensitivity is an order of magnitude above what is needed for a motion sensor in most applications.”

Substitution of traditional materials for medical devices and implants to propel global medical polymers market to 2022

Medical polymers are utilized for a variety of human contact and non-contact applications in the medical industry. These materials are chiefly used in the manufacture of medical implants, devices, disposables (gloves, vials, tools), and packaging. Medical polymers are biocompatible in nature and either remain inert or are easily processed by the human body. Allied Market Research expects medical polymers market to garner US$19,014 mln by 2022, registering a CAGR of 13% during the forecast period 2016-2022.  The growth in investment towards research and development, increase in adoption of medical polymers and development of low cost materials are driving demand for medical polymers in the healthcare industry. Medical polymers are adopted widely across the healthcare industry with significant efforts to commercialize new medical polymers to meet the specification of high end applications. Demand for polymers in healthcare markets is growing significantly owing to a significant upsurge in the demand for medical implants, whereas demand for implants is growing primarily due to increased incidences of chronic diseases and increasing global geriatric population. Demand is witnessing significant growth in all the regions, due to rapid acceptance and adoption of polymers from product designing to final product manufacturing. Although several polymers are biocompatible, not all are approved for commercial use. The key players in the global medical polymers market have adopted various business strategies, such as research and development, product launch, agreement, acquisition, collaboration, expansion, and partnership, to sustain the intense market competition. Large amounts of investments are ongoing to develop implants and devices using various polymers driven by their versatility and stability. This is further expected to increase the adoption of polymers for medical applications and enhance the attractiveness of the medical polymers market for industry participants. Resins such as PEEK and PE, especially ultrahigh molecular weight polyethylene (UHMWPE), possess the maximum market potential in the medical polymer segments. These polymers are gaining popularity owing to their structural strength, bio-inertness, commercial viability, and bio-compatibility. PEEK and UHMWPE find increased usage in medical implants, including orthopaedic and electronic implantable devices. PP, PC, and other resins, including ABS, PMMA, and PET, also show increased utilization in manufacturing medical devices. These engineering thermoplastics exhibit excellent stability, durability, and formability and are preferred over metals and polymer for designing medical devices and implants. PVC is another key segment used for manufacturing medical devices and disposables. PS is used in human-contact applications owing to its non-toxicity and stability. Acrylates are used to produce hydrogels, which are applicable in wound-care, drug delivery, and tissue engineering. Elastomers are mostly used in sealing, packaging, and disposables such as gloves. Biodegradable plastics including PLA, PGA, and PLGA are being developed for use in disposables and packaging applications as substitutes for PE and PP. 


Research raises hope for erbium-based integrated photonics device

An Arizona State University researcher has made another breakthrough using the rare-earth metal erbium as the gain material for an optical amplifier, this time with an achievement that will enable its use for the first time with small chip optical technologies. The discovery attains a decades-long goal in the field of photonic integration, in which different small optical components are tightly combined for better performance and ease of fabrication.

Details of the new optical amplification, "Giant optical gain in a single-crystal erbium chloride silicate nanowire," were published in the July online edition of Nature Photonics.
Cun-Zheng Ning, an ASU electrical engineering professor, and Hao Sun from China's Tsinghua University, and their teams have succeeded in raising erbium's optical gain from the typical low level of a few dB to over 100 dB per centimeter of propagation. The significant increase in optical gain will make it possible for erbium-based materials to be integrated on a chip for optical amplifiers and lasers.
