What is Mi-Rack?
A smart sensor that detects urination and defecation, and sends alerts to your smartphone
Mi-Rack is an innovative sensor that automatically detects the timing of urination or defecation and notifies your smartphone in real time.
Simply place it under the body—no complicated setup, wiring, or installation work is required. You can start using it right out of the box.
With its patent-pending technology, Mi-Rack accurately senses even subtle changes, providing reliable support for caregivers and parents during toilet training.
It helps reduce the burden of care at home or in facilities and brings peace of mind to both families and staff.
Made from a soft material only 5mm thick, Mi-Rack is comfortable even for long hours of use. It runs on batteries and can operate continuously for about six months, requiring minimal maintenance.
Together with easy-to-understand diagrams and app screens, you can experience its simple and intuitive design firsthand.
Designed for Usability and Comfort
Mi-Rack has been carefully engineered to provide exceptional comfort and ease of use across a variety of environments—including nursing care, medical settings, and childcare. It is trusted by many families and care facilities for three key reasons: long-term usability, user comfort, and clear, intuitive operation.
Continuous Operation for Approximately Six Months
Mi-Rack operates on three AAA batteries and can function continuously for about six months.
When replacement is needed, standard batteries can be easily purchased at convenience stores or retailers?no special tools or procedures are required.
This ensures safe, reliable operation with minimal maintenance in everyday use.
Soft, Flexible Material for Maximum Comfort
The sensor is made from a soft material less than 5mm thick, minimizing any sense of discomfort even when seated.
Its gentle texture is suitable for extended use, providing comfort and safety for the user.
Mi-Rack can be placed naturally in various environments, such as under nursing beds, wheelchairs, or potty training mats, without interfering with daily routines.
Real-Time Notifications to Your Smartphone
When urination or defecation is detected, Mi-Rack sends an instant notification to your smartphone via the dedicated mobile application.
Alerts are displayed with clear color indicators and icons, helping caregivers respond promptly and efficiently.
The system is compatible with both iPhone and Android devices, allowing anyone to use it easily and confidently.
Supporting Daily Life in Various Settings
Mi-Rack is a sensor developed to assist individuals who have difficulty recognizing the urge to urinate or defecate, while reducing the burden on caregivers.
It can be easily placed on beds or wheelchairs to detect changes in excretion and send notifications directly to a smartphone.
From home care to medical facilities, Mi-Rack is being adopted in a wide range of settings.
For Individuals with Lower-Body Paralysis
Even for those who have limited sensation related to urination or defecation, Mi-Rack detects changes and sends alerts to their smartphone.
By knowing the appropriate timing for assistance, it becomes easier to maintain cleanliness and hygiene, providing peace of mind for both users and caregivers.
For Elderly Users
Mi-Rack is ideal for home caregiving as well as monitoring in nursing facilities.
It can be installed on beds or wheelchairs, allowing caregivers to monitor excretion timing even during the night or from a distance.
This helps reduce the burden of care and supports a more comfortable daily life.
For Individuals with Loss of Sensation
Mi-Rack is also suitable for those who have diminished excretory sensation due to illness or injury.
By detecting even subtle changes and sending notifications, it helps prevent discomfort or soiling of clothing before it occurs.
For Babies in Diapers
Mi-Rack is also suitable for babies who are still wearing diapers.
It detects the timing of urination and sends a notification to a parent’s smartphone, helping them understand their baby’s natural rhythm.
This allows for timely diaper changes, keeping the baby comfortable and preventing skin irritation.
Never Give Up on What You Can Do
Supporting your “own way of living” with gentle technology
Mi-Rack is a non-contact monitoring sensor that detects urination and defecation timing and sends alerts to your smartphone.
The idea for Mi-Rack was born from an encounter with a woman living with a serious illness.
She was suffering from multiple sclerosis and had lost the ability to sense when she needed to use the bathroom.
Her story deeply moved us — and inspired us to find a way to help.
From that wish, Mi-Rack was created.
Simply place it under the bed, and it gently supports both users and caregivers by reducing the burden of daily care.
Through the power of technology, Mi-Rack helps people regain the confidence to say, “I can.”
