STMicroelectronics’ Reference Design Enables Compact and
Cost-Effective Wearables with Social-Distancing, Contact-Tracing,
and Remote Capabilities
- Scalable solution leverages Bluetooth LE SoC, MEMS
accelerometer, and Sub-GHz RF transceiver for accuracy,
anti-tampering, remote notifications, and long battery
life
- Suited to bands and bracelets for use in open-air or closed
professional environments such as factories, offices, and medical
facilities
Geneva, June 8, 2020 – STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers
across the spectrum of electronics applications, announces the
availability of a compact and cost-effective reference design
ideally suited for monitoring social distancing, assuring remote
operation, provisioning, as well as warning, anti-tampering, and
potentially providing contact tracing to protect human health in
all environments, including in response to global or local pandemic
conditions.
Leveraging Bluetooth Low Energy technology through its
incorporation of ST’s ultra-low-power BlueNRG-2 System-on-Chip with
tunable RF output power, the BlueNRG-Tile reference design measures
the signal strength of nearby Bluetooth non-connecting beacons and,
in real-time, calculates proximity to these sources. The circuit
can be provisioned and then operate, issuing warnings when another
beacon intrudes on an adjustable perimeter or when tampered with –
even when not connected to a smartphone or 5G network. The base
reference design can be supplemented with ST’s S2-LP sub-GHz
ultra-low-power RF transceiver to add bi-directional tag-to-cloud
communication through the Sigfox “0G” Global Network, allowing
private and anonymous tag provisioning, notifications, and an
advisory return-channel for emergency warnings. To assure power
economy and extend battery lifetime, the ultra-low power components
are further enhanced with a MEMS (Micro-Electro-Mechanical Systems)
accelerometer that power cycles the unit when it isn’t moving.
Optionally, internal or external memory could provide long-term
storage of nearby beacons, allowing contact tracing.
“Developing this highly-efficient and cost-effective social
distancing reference design has significant value in any
environment where people need to work safely,” said Benedetto
Vigna, President Analog, MEMS and Sensors Group,
STMicroelectronics. “This compact design can be used as is or
enhanced for a wide range of applications, including as bracelets
and bands or as plugins or add-ons to eyeglasses, helmets, and
masks and shields.”
Several members of the ST Partner Program have evaluated and
adopted the reference design as a foundation for
location-monitoring and contact-tracing platforms. These platforms
provide a range of capabilities, including proximity alerts and
contact recording, using the ST reference design packaged in
compact, ultra-low-power tags.
The Social Distancing reference design, including further
technical detail on its operation, is available on ST.com and
through local ST sales offices. About
