Keeping an eye on children's health throughout the day, from arrival to departure

Editor: Thank you very much for your time today. Can you give us an overview of Cocorin and its features?

Shimazawa: Cocorin was developed with the aim of supporting childcare workers, who are becoming extremely busy due to the diversification of childcare facilities. Our particular focus is to support the mission of all childcare workers, which is to ensure safety and oversight, and to provide childcare and education. The actual service is a "solution to watch over children from the time they arrive at school to the time they leave", and this service is made up of three components: smart wear, transmitters and a dedicated application.

THE FIRST ONE IS "SMARTWEAR", UNDERWEAR FOR CHILDREN, AVAILABLE IN 7 DIFFERENT SIZES FROM SS TO 4L. THE KEY POINT IS THAT THE CHEST AREA IS MADE OF A FABRIC WOVEN WITH A SPECIAL SILVER-PLATED FIBRE THAT IS HIGHLY CONDUCTIVE. THIS IS WHERE THE CHILDREN'S VITAL DATA IS MEASURED, AND VIA A TRANSMITTER DEVICE IN A POCKET AT THE BOTTOM OF THE UNDERWEAR, THE CHILDREN'S INFORMATION IS FED INTO A SPECIAL APP.

The transmitter is equipped with three sensors: a heart rate sensor, an acceleration sensor and a temperature sensor. From this transmitter, information is sent via Bluetooth to the "Cocorin App" installed on a tablet device such as an iPad, where it is possible to monitor each child.
