An AI-Based Diagnostic Tool Detects Wrist Fractures
Imagen’s product ‘OsteoDetect’, an Artificial Intelligence-based diagnostic tool that can quickly detect distal radius wrist fractures is one of the latest products to get US FDA marketing clearance. Its machine learning algorithm studies 2 dimensional x-rays or radiographs for signs of fracture by analysing the posterior-anterior and medial-lateral x-ray images of adult wrists. Studies conducted on comparing fracture detection aided by OsteoDetect and certified orthopaedic surgeons showed that the readers’ ability to detect wrist fractures was improved by using the software as evident by greater sensitivity, specificity, and positive and negative predictive values, compared with unaided standard clinical practice.
A Device that Let’s Others Hear Words You Are Thinking
Arnav Kapoor, an Indian-origin researcher at MIT, has developed a device named ALTEREGO that lets others hear words you are thinking without your making a sound. The product looks like a curved bone hooked to one ear that touches the jaw on the chin and under the lower lip which works by using ‘subvocalisations’ which are the tiny, imperceptible movements in the jaw each time you say a word in your mind. There are four sensors which pick up the signals and transmit them to a computer that has been trained to recognize and convert them back to words which are conveyed to the listener’s mind through bone conduction in the listener’s jawbone, instead of words being openly spoken and conveyed. With the use of Alterego’s technology, one could ask questions soundlessly and get a voice reply only in your ears. Presently the product has an accuracy of 92% which claims to keep improving with the exposure to more types of vibrations and words. Times of India
New Portable Diagnostic Device: Affordable and Accessible
A study undertaken by Dr. Satish Dubey at IIT Delhi has revealed a new portable diagnostic device which is developed by Inito, Bengaluru-based company that can do a dozen tests with the comfort of a person being at home. It has the advantage of reading dozens of diagnostic test strips with a 99.12% correlation when compared to lab grade scanners irrespective of the mobile phone used. This makes it a very reliable tool for portable diagnostics. The device uses patent-pending imaging technology called flat lens that allows a single portable device paired with a smartphone to conduct dozens of diagnostic tests with the same device. The first test that the company has launched is a fertility monitor targeted at couples trying to have a baby. Soon tests for Thyroid, Diabetes and Vitamin D will be added to the device. To add more tests to the device, you just need to update the App and order the strips for the user. Advantages of the device are that it is easy to use, portable, small size, affordable and also third-party strips can be added to the Inito platform by just an App upgrade. The device has won CII Design Award, India Design Mark and Japanese Good Design Award. The device is priced at INR 3195 and is available on Inito’s official website and Amazon. Soon the device will be made available at pharmacies. HT Team
4. Paper Battery
An Indian Innovation Developed using Sewage Water
An innovation by an Indian research scholar, Ramya Veerubhotla at IIT Kharagpur, is the development of a disposable and flexible battery made from paper that could generate power from the bacteria present in sewage water. The battery is made using air cathode and the anode can be made from any carbon-based material. The product is unique because it is very light in weight and the power generation starts within ten seconds, unlike other usual microbial fuel cells which take a couple of days to start power production as the bacteria need time to adjust to the environment. The capacity of power generated from one cell is in the range of a few microwatts. For more power production, one can stack and fold these cells together giving it a compact shape. This research recently received the First prize and a cash award of INR 10 lacs at KPIT Sparkle 2018. www.news18.com
World’s First Home Body Scanner
The product Naked 3D Fitness Tracker is a health and fitness tool for people to track changes in their measurements, body fat percentage, lean mass, fat mass, circumference and overall shape. The start-up has recently raised a $14 million Series A led by Founders Fund. The device has two parts, first is a scale that has sensors and a computer and second being a weight scale that spins a person around so that the stationary mirror can grab the body scan of the user in about 15 seconds. Naked uses infrared light to capture your 3D body model which then gets visualised on the Naked App and alerts the user when there is progress being made by the user in terms of their fitness and also where there is potential for more work to be done. The device has an Intel x86 processor, RAM, 4GB DDR4 RAM and a 64GB SSD which makes it easy to beam the image directly from the device to the user’s phone. The depth data of the users’ body is not uploaded to the cloud instead is being handled on the device itself and also the resultant image is more of a TSA body scan image rather than a 3D avatar. A person can permanently delete the data from his phone if he/ she wishes to. Presently the device is priced at US$ 1395. www.techcrunch.com
6. Wearable Sensor to Detect Stress Levels
A group of researchers under the mentorship of Scientist Alberto Salleo at Stanford University has created a stretchy patch which when applied directly to the skin, takes up sweat and assesses the amount of cortisol the person is producing. This stretchy, rectangular sensor around a membrane/specifically binds only to cortisol but also detects charged ions like sodium or potassium present in our sweat. This patch has a waterproof layer that protects it from contamination. So far, a wearable prototype version has been made but if this is converted into reality it would be very easy to monitor salt imbalances in our bodies and reveal the emotional state of people who are under immense stress and do not open about their situation. The present methods for measuring cortisol levels requires several days of waiting for the lab results. This device seems to solve the waiting problem for the results and is user-friendly. All the user needs to do is to sweat enough to glisten the patch and connect it to a device for analysis which gives results in seconds. The researchers are still working on its reusability though the prototype seems to work multiple times so long as it is not saturated with sweat. A paper co-authored by Scott Keene and Andrew Marais of Stanford University and colleagues at Ecole Nationale Superieure des Mines in France about this wearable sensor was published in Science Advances on 20 July 2018. https://news.stanford. edu/2018/07/20/wearabledevice- measures -cortisol-sweat
World’s First Artificial Flex
Iris is the part of the eye that is colored around the pupil and controls the amount of light entering the eye. It is found to be damaged in conditions like Aniridia in which people are born with a partial or missing iris or it could happen later in life due to traumatic injury or surgical removal due to melanoma. With patients of eye damage, the surgically implanted device known as the CustomFlex Artificial Iris is a boon. Recently this prosthetic iris has got the US FDA approval. The CustomFlex Iris is surgically inserted and held in place either by sutures or eye’s anatomical structures. This iris is made of thin, foldable medical grade silicon and is custom-fitted and colored for each patient. A study of nearly 400 adults and children with Aniridia or other iris defects found that the device was safe and effective, with 70% of participants reporting significant decreases in light sensitivity and glare, as well as improvement in health-related quality of life. The study also found low rates of adverse side effects. As per FDA, the artificial iris is contradicted in patients who have uncontrolled or severe chronic inflammation, abnormally small size of eyes, untreated chronic glaucoma, cataract caused by the rubella virus, abnormal blood vessels on the iris, inner eye infections and certain kind of damaged blood vessels in the retina. Also, pregnant women cannot be its takers.
8. Smart Bandage to Monitor Wounds and Dispense Drugs Made
Sonskusale has recently developed a first of its kind ‘sense-then-respond’ smart bandage which uses sensors to detect subtle biomarkers that signal wound healing. The device has a microprocessor to read the data captured by the sensors, communicate with the mobile and also can direct the bandage to release medication if it is needed. It takes into account things like sensing whether the wound is getting enough oxygen, right pH level is there, what is the temperature near the wound and is there any inflammation? All this information is communicated to a central processor where the doctor already has programmed drug release for antibiotic or growth factor to improve healing. Such a bandage has applications in bed sores, burns and surgical wounds with the advantage of reducing complications from infections and reducing the number of amputations. The key is the timely application of the bandage to the wound site to fasten healing. https://www.digitaltrends.com/cooltech/ smart-bandage
