How do fall detection devices work?

Fall detection devices are like tiny superheroes, constantly monitoring your loved one’s movements. They typically come in two forms: wearables like pendants or bracelets and in-home devices that use sensors to detect falls. Let’s explore the key components of this powerful technology:

1. Accelerometers are the secret weapon.

The accelerometer is the heart of fall detection technology. This little sensor is like a built-in tilt-a-whirl, constantly measuring changes in speed and direction. When a fall occurs, there’s a sudden and dramatic shift in movement. The accelerometer picks this up and sends a signal to the device’s processor.

2. Smart Algorithms: Separating Falls from False Alarms

However, not every bump or bend is a fall. That’s where smart algorithms come in. These programmes analyse the data from the accelerometer, looking for specific patterns that indicate a fall. This could include a sudden drop, a period of no movement after the fall, or a specific angle of impact.

3. Alert Mechanisms

Once a fall is detected, the device activates an alert mechanism. This can include:

i. Audible Alarms: To notify nearby individuals.

ii. Text messages: sent to predefined contacts.

iii. Automated calls are made to emergency services or carers.

iv. Mobile app notifications provide real-time monitoring.

These alerts ensure that help is dispatched quickly, reducing the time a senior may spend unattended after a fall.

Types of Sensors Used for Fall Detection Devices

i. Accelerometers: Measure the rate at which velocity changes.

ii. Gyroscopes: Detect rotational movement.

iii. Barometers: To detect height changes, measure atmospheric pressure.

iv. Proximity Sensors: Determine if the user is close to the ground.

Beyond the Accelerometer: Exploring Fall Detection Devices’ Additional Features

Fall detection devices aren’t one-trick ponies. Many offer additional features that enhance safety and independence.

i. GPS Tracking: Some devices come with GPS functionality, allowing emergency personnel to locate the senior quickly and easily, especially if they’re outdoors when a fall occurs.

ii. Fall Impact Sensors: These sensors go beyond simple movement detection. They can distinguish between a harmless bump and a significant fall, reducing false alarms.

iii. The Manual Help Button: Falls aren’t the only emergencies. Many devices come with a manual help button that seniors can press to summon assistance in any situation.

iv. Water Resistance: For added peace of mind, some devices are water-resistant, allowing seniors to wear them in the shower or bath without worry.

Taking Action: Sending Help When Needed

If the algorithm determines a fall has likely happened, the device will spring into action. Here are some common responses:

i. Automated Alerts: The device may send an automated alert to a monitoring centre. These professionals will then attempt to contact the senior and assess the situation. If there’s no response, they can dispatch emergency services or notify designated contacts.

ii. Two-Way Communication: Some devices have built-in speakers and microphones, allowing for two-way communication. This means seniors can talk directly with the monitoring centre, even if they’re unable to get up.

iii. Manual Help Buttons: Many devices also include a manual alert button that seniors can press if they need help, even if they haven’t fallen.
