Fall Detection Sensors: Uses and Benefits

Did you know that according to the National Safety Council in America, 44,686 people died due to falls at home and at work in 2021? It has also been reported that more than 6.9 million people ended up in hospital emergency room visits due to fall-related accidents that year. Some of the consequences include fractures, long-lasting health complications, and death. Slip-and-fall accidents can occur anywhere, making them a common and dangerous incident. This is where a fall detection sensor comes in. If fallen individuals cannot immediately call for help, a fall detection device can save their lives.


What are fall detection sensors?

Fall detection sensors are devices specifically designed for detecting slips and falls among individuals who may need additional assistance. These technological devices are particularly useful for elderly individuals who have weaker joints and limbs, or other individuals prone to falls due to certain medical conditions. Of course, a fall detection sensor can also be used by all individuals, as slips and falls can occur anywhere and anytime.


Most fall detection technologies are also usually part of medical alert systems, helping people with various health conditions, especially those who live alone. Smart home monitoring systems can also be embedded with fall detection sensors to provide timely assistance in the event of a terrible fall. This reduces the risk of injury or complications, especially for vulnerable individuals living alone in their place.


Fall detection sensors typically utilize a triaxial accelerometer to measure speed, distance, and direction. However, some devices might also use various technologies to detect the sudden change in movement or orientation associated with a fall. Some common types of technologies associated with fall detection sensors are:


  • Accelerometers: These sensors measure acceleration forces and can detect sudden changes in movement or impacts.
  • Pressure sensors: Pressure sensors can be placed on the floor or on furniture surfaces to detect when an individual falls by sensing changes in pressure caused by the impact.
  • Gyroscopes: Gyroscopes measure orientation and angular velocity. When paired with accelerometers, they can provide more accurate data about the direction and force of a fall.
  • Infrared (IR) sensors: IR sensors, on the other hand, can detect changes in infrared radiation caused by a person falling within their field of view.
  • Camera-based systems: These systems use cameras and computer vision algorithms to detect falls based on the visual cues they receive.
  • Wearable technology: Wearable devices such as smartwatches or pendants might also be equipped with accelerometers, gyroscopes, and other sensors that can detect falls and send emergency alerts.


How do fall detection sensors work?

Fall detection sensors work by monitoring changes in the environment. This includes physical moment, orientation, pressure, and other relevant parameters to identify when a person has fallen or changed their body position dramatically.


Here is a general overview of how a fall detection sensor usually works:


  1. Sensor placement: First comes the sensor placement. Fall detection sensors can be placed in various locations, depending on the technology used or the device. They may be installed on wearable devices like smartwatches or pendants, embedded in furniture or flooring, integrated into the environment through cameras or infrared sensors, and more.
  2. Data collection: Once placed, the sensors will continuously collect data relevant to detecting falls. This data may include acceleration, orientation, pressure, infrared radiation, or visual information. It may depend on the type of sensor.
  3. Signal processing: The collected data is then processed by algorithms designed to recognize patterns or changes associated with falls. For example, sudden changes in acceleration or orientation, impact forces exceeding a certain threshold, or changes in pressure indicative of a body falling to the ground.
  4. Fall detection algorithms: Fall detection algorithms analyze the processed data to differentiate between normal activities and potential falls or accidents. These algorithms are typically trained using data sets that include examples of falls as well as various activities of daily living to improve their accuracy.
  5. Triggering Alerts: When the algorithm detects a potential fall, it triggers an alert to notify caregivers and family members. If the fall detection device is connected to a professional monitoring center or emergency services, it will also be able to send alerts to the proper responders or healthcare professionals. This alert may be sent via a smartphone app, a dedicated home monitoring system, or directly to a call center associated with a medical alert service.
  6. Response and Assistance: Once an alert is triggered and sent, caregivers or emergency first responders can take appropriate action. This includes contacting the person who fell, checking on their well-being, providing assistance if needed, or dispatching professional medical help if necessary.

To put it simply, fall detection devices work by combining advanced technologies, gathering and analyzing data, and sending alerts for the proper response. Fall detection sensors help ensure the safety and well-being of residents and occupants of a living space, whether they are elderly people or people with certain medical conditions.
