It is predicted that by 2050, the population over the age of 60 is expected to reach 2 billion worlds. In this regard, this will represent more than one-fifth of the world. With the increase in the old population, more advanced home monitoring is still allowed to maintain personal autonomy. According to the data of the US Disease Control and Prevention Center, there are nearly four-quarters of the elderly in the year, and the older is the main reason for the admission of the hospital, as shown in Figure 1. The fall detection system can use the sensor-driven solution to provide non-contact, non-privacy intrusion sensing by accurate point cloud data.

How Texas Instruments millimeter wave sensors help solve the challenges of today's fall detection system
TI IWR6843 fall detection millimeter wave sensor may be implemented with high accuracy, without contact with the person being monitored. In addition to the material by induction, the sensor may also be detected under all lighting conditions, and provides data in a range of scene parameters, angle and speed of the system by using a 3D point cloud information
Here, we have a TI of "human fall detection and gesture" demonstration, showing the 60 GHz IWR6843 single sensor chip from Texas Instruments and its ability to be able to detect when the wall height and attitude of the staff installed in the sensor. The reason for using IWR6843 because the 60GHz band has opened worldwide for industrial RF sensing applications
This demonstrates the use of the azimuth and elevation are IWR6843ISK-ODS EVM 120 degrees. In this presentation, EVM is installed at a height of 6.5 feet, and the wide field field of view helps to increase the visibility of the ground and minimize dead angles. This demonstration can also be modified to use the IWR6843AOPEVM package antenna EVM in Texas Instruments.
Remote non-contact gesture is detected
Currently many older alarm systems require the user presses a button to trigger a response, but if they fall unconscious because it is impossible to press the button. With Texas Instrument millimeter wave sensors, the system can detect potential falls and trigger response, so you don't need to bring your safety alert button.
Enable non-invasive detection of fall
When TI millimeter wave sensor is used as the only system techniques, which provides more flexibility for the system in a home or building physical posture. Since millimeter wave technology is captured by point cloud data rather than an image, the drop detection system based on millimeter wave technology can be used in a more sensitive area, such as a home bathroom or bedroom. The sensor can also be detected by plastic and paper gypsum boards, making it carefully arranged and achieves a more simplified home design.
Rich, enabling accurate measurement point cloud data
Monitoring system for the elderly, must have a high resolution in order to distinguish the posture and height of the person in the normal state. The millimeter wave sensor of Texas Instruments outputs 3D point clouds and speed information to help determine if the person falls.
in conclusion
Texas Instruments millimeter wave sensor is intelligent solutions for home monitoring system can be used to monitor the elderly and emergency situations. When used in a fall detection system, the IWR6843 of Texas Instruments can perform high-precision monitoring while maintaining personal privacy and robustness under all environmental conditions without wearing equipment.
