Kardian Selects XeThru For Contactless Fall Detection System

Among elderly and physically weakened people, falls are a leading cause of injury. After a fall, fast response time can be critical to avoid more serious injury or trauma. Trusting that someone is alerted if you fall, can be vital to reduce fear that cuts down on everyday activities and life quality.

Kardian, a US start-up coming out of 5 years research program on IR-UWB (impulse radio ultra wide band) radar, will debut its wireless and contactless health monitoring system at the HIMSS18 in Las Vegas from March 6. Using a Novelda XeThru X4 sensor, Kardian has created a system that promises to solve some key challenges in health care.

“With the XeThru UWB radar sensor, we have the right technology to create a near-perfect fall detection solution able to detect 99% of all falls - including sliding falls. This is the world's first and only commercial and medical grade level fall detection system that is 100% contactless."
- Sam SJ Yang, Managaing Director of Kardian.

Sam SJ Yang, shares further detail and background: "Most wearables, equipped with accelerometers, gyroscope and even barometer sensors can only detect hard falls. Slow, sliding falls are often miss-detected and there have been several cases where customers ended up not receiving help due to its limitations. Hospitals and senior care facilities cannot rely on wearables and therefore a vast majority of them uses pressure sensitive pad based fall detection systems. Unfortunately, unless the pads are maintained properly and replaced every few months, the system can cause sporadic false alarms. Replacement pads can also cost hundreds of dollars per year per bed. Kardian’s fall detection system uses Novelda's XeThru sensor with the X4 ultra wide band impulse System-on-Chip and scans a room continuously. It looks for sudden falls, sit-ups from the bed and slow/sliding falls via time of flight and distance. Furthermore, it goes through a series of algorithms to confirm a potential fall by looking at post-fall vital signs including movement and breathing rate. False alarms are greatly reduced thanks to its ability to detect multiple people in the scanning zone, using its patented presence detection and people counting technology. It even has the ability to look for falls on a bed or sofa compared to falls to the floor. "


Kardian's sensor can send real-time data over Wi-Fi to the designated caretaker using the mobile app. There is also a "call patient" option to make a direct call or signing up with Kardian's partner RAPIDSOS and be directly connected to 911 / first responders.


Since Kardian's fall detection system is wireless and contactless, there is no device that must be worn or placed on the bed. The sensor can be mounted in the ceiling, on the wall, or on a nightstand. This enables the sensor to monitor a complete room such as a bathroom. Privacy is maintained as Kardian's devices are not equipped with any type of camera and therefore it is impossible for it to identify a user.


Kardian's sensor can be placed in the ceiling or on a wall and maintain privacy as it cannot identify a user.


The system is not affected by dirt, dust, light or temperature. There is no physical maintenance to worry about, and never a need to replace any parts. The sensor emits 10,000 - 100,000 less energy than a Wi-Fi router, and is completely without health-risk.

Kardian's fall detection solution is suitable for hospitals, senior care facilities, and even in personal homes for use in bathrooms and bedrooms. They will be exhibiting at booth #11307 at Sands Expo, Las Vegas during HIMSS18 from March 6 ~ 9. Appointments can be made on their website: http://kardian.io/.
