First, wearable devices
Studies have shown that the number of people wearing smart watches is growing. Gartner recently reported that global wearable device sales increased by 17% in 2017. The agency predicts that 2020 will be a watershed in the development of the global technology industry. Wearables revenue will surpass the smartphone market, with a scale of $61.7 billion and sales of 477.75 million.
As the name suggests, IoT devices are smart and interconnected. They come in a variety of form factors with optimized connection options and power consumption for specific applications. For healthcare applications, sensors on the wearable device provide information to the cloud platform at predetermined time intervals to analyze and search for anomalous events (eg, hypertension, hypoxia, low/high heart rate, high glucose, etc.). In addition, if a drug is effective, it can provide feedback if the quality of sleep is related to poor vital signs in a region or even signs of an infectious disease.
Although blood testing is always required, as wearable technology becomes more advanced and accurate, more healthcare measurements can be made through this technique and will shift from invasive to non-invasive.
Second, the external sensor
Technology has come a long way. Small wearable devicesí¬such as smart watches, rings, and patchesí¬can be used in low-power modes, and batteries can be used for many years. Many people transmit data over Bluetooth, Wi-Fi, and even cellular mobile networking. This is critical for patients with chronic conditions and poor health, which largely eliminates their potential to return to the hospital. They can now wear sensors at home to monitor their vital signs, even in the presence of abnormal data or Remind the doctor when it causes concern.
Today, wireless sensor systems can collect medical data that has never been acquired before. Sensor data, sensors, microcontrollers, microprocessors, and gateways are further analyzed and sent to the cloud center before being sent to the caregiver. IoT device networks can be directly connected to each other to capture and share important data.
Third, active preventive care
Wearables and sensors allow people to manage their health care and well-being. For patients who are ill or who try to prevent a worsening condition, wearable devices and general external sensors can provide a degree of autonomy while still allowing the doctor to control the actions that need to be taken. Particularly suitable for elderly or demented patients, it also has a GPS that can be pre-set to a safe area and can notify the appropriate party to let them know that the person is at risk.
In addition, data collected from these IoT devices can be used not only by medical service providers, but also by insurance companies, hospitals, fitness centers, etc., to arrive at various conclusions. All of this can be achieved at millions of people in a relatively short period of time at very low cost. But so far, we have to rely on the resulting patient library for research, most of which are done manually.
Traditionally, when people think of family care, they consider blood pressure measurement and diabetes testing. But with the new IoT technology, more and more things can be done at home. Although there are still challenges to overcome (for example, sensors need to transmit data and need nearby hotspots; or if the device is Bluetooth connected, it will need another device, such as a cell phone), but the Internet of Things will still improve the healthcare system. And completely change the way we look at health.
