Hong Kong-based microelectronics company, Dayton Industrial, has launched a new wearable and web-based solution designed to enable remote healthcare/telecare applications support from an open platform.
The 38 by 12 mm ‘Link2Care Smartwatch DA13700’ features a 3D motion sensor for activity records, inactivity alerts, sleep monitoring, and fall detection. By pressing the “SOS” key, the user can activate an SOS alert message with their health information—including name, gender, age, blood type, and any drug allergies—and location that is sent to predefined mobile phone numbers and uploaded to a Cloud server and service center for emergency response.
Nordic’s nRF52832 SoC provides the Bluetooth® 5.3 connectivity enabling incoming calls, schedules, messages, social media notifications, and more to be relayed between the user’s smartphone and the Link2Care Smartwatch DA13700. In addition, the SoC provides mesh networking capability, a beacon profile for indoor location tracking, and NFC support.
Nordic’s nRF9160 SiP provides the device with LTE-M/NB-IoT cellular connectivity and GNSS to report the location of the wearer to nominated caregivers along with any SOS alert. Further information, including sleep/activity stats and wellness data such as daily step count/distance and calories burned, can be uploaded to the Cloud and customer service center via a cellular network.
The Link2Care Smartwatch DA13700 uses a 110 mAh Li-ion rechargeable battery to provide battery life of up to five days and a SOS alert once per day, depending on usage profiles and conditions. This low power consumption is achieved thanks in part to the ultra low power characteristics of the Nordic nRF52832 SoC and nRF9160 SiP.
“Dayton is one of Nordic’s strategic partners. The company has always received excellent technical support from Nordic,” says Tony Chung, Sales and Marketing Manager, Dayton Industrial Co. Ltd.
