Prodigy has launched the Disposable Electronics Wristband (DEW), a wearable tracking solution designed to assist medical authorities to track persons who require to undergo quarantine at designated place. When paired with a mobile application, the DEW wristband ascertains the person is staying at the designated places, provides alerts in case the person leaves the designated place or tampers with the device, and supports an efficient management of the quarantine process amid the coronavirus (COVID-19) pandemic.

The wristband is developed using Nordic Semiconductor’s NRF52805 controller, an SoC ARM Cortex-M4 processor clocked at 64MHz. This single-mode system fully supports the 2.4GHz Bluetooth beacon technology.

Using Bluetooth LE connectivity, the DEW-band communicates with a paired smartphone, from where an iOS and Android companion app can be used to customize the device, input personal information, and view graphical representations of current and past data.

The wristband communicates on standard beacon protocols, including Apple iBeacon and Hong Kong Health department Stay-at-Home SHS protocol. The BLE data packet broadcasts every 1s. Data includes company ID, model, major/minor number, battery level, operation mode, and strap connection/magnetic sensor status. Each wristband has a security lock to prevent tampering. Once activated, it alerts the central administration system for deactivation or removal.

Powered with a 3V primary Lithium battery, the wristband can operate in active mode up to 12 months based on beacon broadcast interval; and lasts for multi-year sleep mode when kept in storage. The wristband easily meets the 2- to 4-week quarantine requirement set by the hospitals and public health departments.

DEW weighs only 12g with adjustable wrist strap of 195mm in length and 16mm in width. The main case is 58mm in length and 36mm in width. The wristband is made with a durable TPU material that has great characteristics in both flexibility and strength. It is also water resistant and friendly to the environment.
