These wearable devices will treat allergies

There are more and more cases of allergies around the world. According to the British Allergy Agency, about 21 million adults have allergic symptoms, and up to one-fifth of them suffer from allergic rhinitis (also known as hay fever). In the past decade, the number of food allergies in the UK has doubled, and the 2013 US Centers for Disease Control and Prevention found that between 1997 and 2011, children with food allergies increased by about 50%.

However, there are no drugs that can cure all allergies, and patients can only avoid allergens. At the same time, some startups and university research institutes are studying how to prevent and treat allergies, which is a boon for patients. A sophisticated food allergen detector that can be disguised as a stylish necklace; an air allergen tracker can camouflage a beautiful clip; can sense severe allergic reactions and provide life-saving wearable devices, these three Inspiring innovation can really prevent and treat allergies.

Lab on the necklace

Although Nima in 6Sensor Labs is not really a wearable device, it is a device capable of detecting trace amounts of gluten, specifically to 20 PPM (20 parts per million) or lower, which is the safety issued by the European Union and the FDA. Minimum guidelines for gluten-free labels and most gluten allergy sufferers. Nima's small high-tech uses chemical analysis rather than a representative sample of scanned food.

The first true wearable allergen detection device allergy amulet is currently in preparation and is expected to be available in 2018. Abigail Barnes, a Yale graduate, and Dr. Joseph BelBruno, a professor of chemistry at Dartmouth College, are not only their brainchild, but also a chic necklace with special abilities. A strip of chemicals is attached to the allergic amulet to detect allergens within minutes. The technology is very sensitive, detecting allergen levels to PPT (X parts per trillion), far below the minimum guidelines for EU and FDA gluten-free labels (20 PPM) and other allergen safety thresholds.

However, allergy amulets are not foolproof. Because strips can only test representative samples, you may miss some latent allergens in your food. For this reason, allergy amulets are an extra device for defense, not the last wall for allergen detection. Although allergy amulets will currently only be tested for peanut allergens and will be extended to eight common allergen tests in the future, co-founder Abigail Barnes tells us that her company will eventually be able to customize personal allergy amulets for customers to detect coriander soy. Wait for a variety of allergens.

At the same time, a venture capital startup DOTS device is developing an allergen testing wearable device. Its patent-pending technology can be said to be black technology, but the company currently refuses to express any opinions.

Challenge allergens in the air

If you suffer from allergic rhinitis, you know that avoiding exposure to airborne allergens such as pollen, dust, and mold spores is simply impossible. TZOA is here to save you. Its crowdfunding clips can detect everything in the environment, including pollution levels, humidity, UV, temperature, and most importantly allergen particles in the air. Thanks to advanced optics and laser diode technology, TTZA can detect tiny particles up to 10 microns (air allergens) and 2.5 microns (air pollution). The TZOA clip will be available next month and its detected air quality information will be displayed in the smartphone app. Its data will also be synced to the cloud and used to create maps of allergens and pollution hotspots. The clips can monitor indoor and outdoor air quality, and the app will provide real-time advice. If the map shows high pollen content in nearby parks, you will be advised to stay away; if TZOA senses indoor dust and mold spores, it is recommended that you open the window.

Google's smart contact lenses, patented last year, will offer similar features. The patent states that the lens "can sense the number of any organism, the chemical and/or microbiological characteristics of the environment... and the level of allergens".

In order to face Google, the Korean Copyright Office recently announced that Samsung applied for a patent for similar smart contact lenses two years ago. It is said to detect allergens such as trees and grass pollen in the air. However, these devices are still a few years away from the real market.

If high-tech companies want to be taken seriously by allergic patients and the medical community, the key is to detect traces and accurate readings. “It’s very important that the equipment is researched and thoroughly tested and subjected to rigorous scientific testing and false positives,” said Holly Shaw, a UK-based allergy agency nurse consultant.

Wearable adrenaline syringe

When an allergic reaction occurs, the injection of adrenaline as soon as possible is the gold treatment standard. In order to save themselves in an emergency, allergic patients often carry the injectable adrenaline “EpiPen”. However, the design of "EpiPen" has not changed since the 1980s, and many people feel very tired. All of this will change, and allergy expert Dr. Michael Langen has applied for a patent for the wearable adrenaline syringe "Epibracelet" and is expected to invest soon.

A team at the Harvard University's Weiss Bioengineering Institute is developing implantable, second-layer skin and bundled wearable devices that sense severe allergic reactions and immediately inject adrenaline. "Our goal is to develop reliable equipment that detects critical physiological and biochemical signals to detect the initial stages of allergies," said John Osborne, senior engineer and project technology lead at the Wes Institute. “Once the critical threshold is reached, the device will alert the caregiver and automatically inject the appropriate dose of adrenaline.” The project began in December and was funded by the KeepSmilin4Abbie Foundation, Abbie Benford, a 15-year-old girl from Massachusetts, due to a severe allergic reaction. Passed away in 2013. Sadly, if Abbie can receive adrenaline treatment in time, she will not die. So his family set up the foundation, hoping to help others. These life-saving technologies and other allergic-related innovations are long-awaited and I hope there will be more in the future.

Outdoor Emergency Portable Power Station

The off-grid segment is expected to be the fastest-growing market segment in the portable power station market, by application, during the forecast period.

The portable power station market is segmented by application into emergency power, off-grid power, and automotive. The off-gird power segment is projected to grow at the highest rate during the forecast period. The demand to power modern electronic equipment such as laptops, smartphones, etc., is driving the portable power station market for the off-grid segment. The growth of this segment is also driven by the increase of camping and outdoor recreational activities, and the growing use of smart electronic devices in regions such as North America, Europe, and Asia Pacific.

North America is expected to account for the largest market size during the forecast period.

The market is segmented by region into North America, South America, Europe, Asia Pacific, and Middle East & Africa. Of these, North America is the largest portable power station market in the world, predominantly due to the US, and the trend is expected to be the same during the forecast period. The market in the region is driven by the growing emphasis on camping and outdoor recreational activities, and the increasing use of smart electronic devices, and the subsequent need for connectivity, which requires power.
