AuthorBY- ANUSHRI M The wireless communication plays a major role in today's modern world. Most of the technology we use is connected to the internet for an ease of use and backing up data for future analysis. The WiFi is the primary tool used for internet connectivity these days but it too has its own merits and demerits. WIFI AND ITS DRAWBACKS: WiFi (Wireless Fidelity) is a wireless networking technology that uses radio waves to create wireless network connections, provide internet access, or transmit data. WiFi operates within the radio spectrum. The radio spectrum is part of the electromagnetic spectrum that have frequencies from 3 Hz to 3,000 GHz. WiFi connections tend to be insecure. Its lack of security generally comes from its wide signal range, allowing the network to be accessed within a 20 to 50-meter radius. Another disadvantage of WiFi connections is that signals tend to be unreliable. That is because radio frequencies are still subject to various external interferences. WHAT IS LIFI ? Light Fidelity (LiFi) is a wireless optical networking technology that uses visible light from light emitting diode(LED) for data transmission. The term LiFi was coined by professor Harald Haas in the year 2011 at his global TED talk where he introduced the idea of "wireless data from every light". WORKING OF LIFI : LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can be changed at extremely high speeds. This change in intensity becomes a digital signal which can carry information from the internet to a user and back again. Multiple lights can be added to a single network, so that you can move around from light to light without losing your connection. You don't have to be directly under a lamp to use LiFi. The digital signal is also carried by light reflected off walls and other surfaces. WHY LIFI ? One main advantage of Li-Fi is security. Since light cannot pass through opaque structures, Li-Fi Internet is available only to the users within a room and cannot be breached by users in other rooms or buildings. LiFi is much more efficient when it comes to cost and power consumption. Due to the use of LED bulbs, LiFi can be made available everywhere by replacing traditional LED bulbs with LiFi compatible bulbs.

AuthorBY- DIVIYA BHAVAANI M.B As technology evolves, OEMs are widely exploring the scope of adopting the latest technology trends to Medical Electronics. Trends such as Artificial Intelligence, Internet of Things etc, are set to have an enormous impact on the health-care industry. Here are some of the recent Trends in Medical Electronics that are expected to have a huge impact on the segment: Wearable gadgets – The modern-day innovative, secure, and highly efficient wearable devices are helping people to maintain their daily routines, keep track of their health and be more aware of their health. Wearable devices such as smartwatches, activity trackers, health monitors etc. come equipped with sensors to help users monitor heart rate, BP, Glucose, weight, SPO2, etc., while maintaining the log of such parameters. This data can optionally be shared with the physicians thereby contributing significantly to a person’s well-being. Blockchain Systems – Blockchain systems work like Electronic Medical Records (EMR), where the patient’s health record information is digitally stored on the cloud with minimal space consumption. The Blockchain technology allows a patient, physicians or any trusted users to faithfully and securely access or share the information remotely. Using this, patients can easily connect to multiple hospitals and collect their medical reports automatically and a physician can have a look into the history of the patient’s medical reports and provide an accurate diagnosis, along with effective and cost-effective care. Telemedicine – The modern medical applications both wired and wireless are making the life of patients, especially the elderly and physically challenged, easier by allowing them to consult and get prescriptions from doctors on their smartphones. The doctors can also remotely monitor the patient’s health and make diagnosis and treatment decisions quickly. Artificial Intelligence (AI) – Artificial Intelligence is set to change the health-care industry in many ways. AI-based devices can process information with speed and accuracy and help doctors provide a diagnosis or create a treatment plan. Design of BOTs (using AI/ML/DL) are underway to assess and diagnose the medical situation/circumstance and prepare report/plan/suggestion to assist the medical/paramedic personnel. AI along with Machine Learning(ML) can be used to explore chemical reactions in the drug industry, digitize medical records, schedule appointments online, help surgeons offer deep insights on the surgery, interpret multiple data sources at the same time from different variables, provide enhanced treatments in cases such as radiology and more. AI is helping the health-care industry to transform from traditional treatment into targeted treatments and personalized therapies. Internet of Things (IoT) – Internet of things is one of the rapidly growing technologies which has opened a world of possibilities in the healthcare industry. Internet of Medical Devices (IOMT) helps in real-time monitoring of the patient and notifying the physicians by means of smart medical devices connected to a smartphone with accurate data for early treatment. The IoT based medical devices such as glucose monitor, insulin pens, blood pressure monitors, etc are among the most used medical devices at homes and in hospitals to monitor and provide real-time information to doctors for quick and accurate diagnosis and treatment. Conclusion: These are just a few of the technologies that are being adopted by the healthcare industry. As technologies evolve, the way healthcare providers interact with patients and deliver care is also changing and the healthcare and medical electronics industries are about to witness a lot more significant changes in the upcoming years. AuthorBY- SUPRAJA G.S The first chemical element with the highest percentage in the human body is Oxygen, all cells in our body need oxygen to create energy efficiently, hence it plays a vital role. During this COVID – 19 Pandemic, the patients affected with the Coronavirus suffered from Breathlessness, when the virus spreads it blocks the entry points of oxygenated blood into your lungs. To support and cure the patients at early-stage medical oxygen was widely used. So, let’s discuss what is medical oxygen production method and the reason behind the demand. What Is Medical Oxygen? Medical oxygen is high purity oxygen that is used for medical treatments and is developed for use in the human body. No other types of gases are allowed to prevent contamination. This type of oxygen can only be generated by medical air compressors with which we can attain a purity of 99.5 percentage. Methods to produce Medical Oxygen. There are several methods to produce Medical Oxygen, out of which production through Air Separation Units (ASU’s) is most common. ASU’s are production plants that separate large volumes of gases. They use a method called Fractional Distillation to produce pure oxygen from atmospheric air, which is first cooled to -181°C, Oxygen liquefies at this point. Since the boiling point of Nitrogen is -196°C, it remains in a gaseous state. But Argon has a boiling point similar to that of oxygen (–186°C) and hence a significant amount of Argon liquifies along with Oxygen. The resultant mixture of Oxygen and Argon is drained, decompressed and passed through a second low-pressure distillation vessel for further purification. We then get the output as final purified liquid oxygen, which is then transported using cryogenic containers. Oxygen can also be produced non-cryogenically, in gaseous form, using Selective Adsorption. This method leverages the property that under high pressure, gases tend to be attracted to solid surfaces. Hospitals can also opt for on-site generation of oxygen by this method, where oxygen is produced from ambient air by concentrating it. Producing oxygen near hospitals has the additional advantage of eliminating the need for transportation. In addition to the above sources of medical oxygen, there are also portable oxygen generators known as Oxygen Concentrators that can be used at home. Oxygen concentrators are simple devices that take in ambient air and increase the oxygen concentration, by filtering out and throwing away nitrogen, while the cylinders need to be refilled, the Oxygen Concentrators can work 24 x 7. How much Oxygen is produced in India? During the first wave, the demand for liquid medical oxygen (LMO) increased from 700 metric tonnes per day (MTPD) to 2,800 MTPD. But during the second wave, it has skyrocketed to 5,000 MTPD. It was only in the second week of April when demand for medical oxygen in India witnessed a five-fold jump. On April 21 demand was 5500 MTPD and production was 7287 MT and the government had a buffer stock of 50,000 MT. As you can see the goods were surplus then why there was a demand at hospitals for medical oxygen. Reason for the Demand for Medical Oxygen. It is clear that that there is no shortage of medical oxygen capacity in the country. Hospitals receive oxygen both in cylinders, also in tankers based on their stocking capacities and daily needs. The non-availability in critical states is primarily due to a lack of foresight and planning. If all available resources across the country had been mapped, activated in time with a foolproof logistical model in place, this situation would have never occurred. After this crisis EG 2 came forward to resolve the crisis, If these measures had been taken before, a normal citizen wouldn’t have been running from pillar to post to receive treatment or to get vaccinated. Governments must realize that what Medical Oxygen is to COVID-19 treatment, citizens are to the existence of the nation. |
