Development Background

In nursing care sites, the introduction of monitoring sensors and bed-exit sensors is progressing to prevent falls, tumbles, and wandering of people requiring nursing care. With the increase in home nursing care, there is a growing demand for bed-exit sensors that can be easily handled and purchased not only by nursing care facilities and hospitals but also by individuals. There are various types of bed-exit sensors that detect the pre-exit behavior of people requiring nursing care and notify caregivers. However, many of conventional ones, such as mat sensors, sensors installed at the foot of the bed, and infrared surveillance, are extremely expensive due to the large-scale system itself, making it difficult for individuals to adopt them. A wireless communication manufacturer working on this issue adopted EnerCera as the key to developing a wearable bed-exit sensor that is easy to handle, low-cost resulting from simplifying and downsizing, and can be attached very smoothly to the body of the person requiring nursing care.

The EnerCera Advantages

EnerCera Pouch
Use Case

Contributes to preventing accidents such as falls (out of bed, etc.) for those who require nursing care; reducing the burden of nighttime monitoring for caregivers.
Expected Technological Contribution

Supports power supply for wearable devices in medical, nursing, and other healthcare fields with its low-profile, high-safety features.

The EnerCera Advantages

✔️ Realizing a wearable device that is not bulky and obtrusive
✔️ A battery with high safety even when worn by a person
✔️ Reasonable price compared to a large-scale equipment in hospitals

Thin and Unobtrusive design of wearable device

As EnerCera is a lithium-ion rechargeable battery with a thickness of only 0.45mm and weighing less than 1g, it enables the adopted device to be thin and compact that can be worn without sense of discomfort.

A battery with high safety

EnerCera is an ideal battery for wearable devices that are worn all the time, as it has no worry of leakage or ignition. EnerCera is a safe lithium-ion rechargeable battery with extremely low potential for overheating, ignition, or explosion, and has obtained the IEC62133 safety certification.

Reasonable price resulting from compact wearable type sensor

By developing a wearable type sensor device instead of an installed type sensor system, it has become possible to provide a bed-exit sensor at a reasonable price that can be purchased by individuals.

Use Case

EnerCera Pouch has been adopted in Ueda Japan Radio's monitoring system for people requiring nursing care, "Mamottene." By combining the high-output EnerCera, it has become possible to transmit sensing data in real-time, enabling the construction of a system that immediately notifies caregivers via a smartphone alert when an abnormality is detected in the person requiring nursing care. This can contribute to preventing accidents such as falls from the bed and reducing the burden of nighttime monitoring for caregivers. Ueda Japan Radio provides a system that detects the pre-exit behavior of people requiring nursing care during sleep and notifies their families, contributing to reducing the risk of falls and the burden of nighttime monitoring.

Expected Technological Contribution

In the future, it is expected that the introduction of wearable devices will further progress in the fields of medical care, nursing, and nursing care. EnerCera will support the power supply of these wearable devices by leveraging its thin and highly safe characteristics.

Testimonials

EnerCera was the only battery solution that enabled us to provide our customers with a device that was thin and lightweight enough for our users to comfortably wear. Since it can be directly soldered to the circuit board, the overall volume of the device could also be reduced through eliminating connectors and battery holders. This greatly expanded our ability to test and realize a wide range of designs. Furthermore, the high-temp resistant model EnerCera allowed our device to support wireless charging, which tends to generate significant heat during charging. In a perfect world, we would greatly appreciate an EnerCera model with double the capacity, even if this means doubling the thickness. Also, a model that boasts built-in protection circuit and safety standard certification would further lower the barrier for use and improve usability.
