18. Light Therapy
Lightwear
“Lightwear” consists of a series of garment- and accessory-based light-emitting wearables designed to
administer light therapy for on-the-go treatment of Seasonal Affective Disorder (SAD). To date, there
have been few successful products developed for wearability and portability to ease the uncomfortable
nature of traditional light box treatment. Lightwear explores the integration of light into 3D printed and
textile substrates to create fashion-forward wearables to address issues related to BLT efficacy, usability,
adoption, and convenience.

The global eyewear market is a $180billion market dominated by one company
Luxottica. If we look at today’s deal whereby BASFisinvesting$25million in Materialise
we could see this as a deal to industrialize 3D printing for many products. But, given
Materialise’s lead in eyewear, is this perhaps the entire play for BASF? Maybe a chemical
company wants to leapfrog polymer, manufacturing, parts production and eyewear

Conclusion
A compact design of see-through NED, featuring a pair of
corrective lenses coated with multiplexed volume holograms,
has been proposed. Based on the simulation, its optical
performance including DE, FOV, MTF, and distortion has been
studied. By eliminating the need for extra glasses or contact
lens, this type of see-through NED could be particularly
appealing to the users who are more or less visually impaired.
In addition to myopia, our future work will extend to
hyperopia, presbyopia, astigmatism, and combinations of
different refractive anomalies.

The engineering of plasmonic colours is a
promising, rapidly emerging research field that
could have a large technological impact. We
highlight basic properties of plasmonic colours
and recent nanofabrication developments,
comparing technology-performance indicators for
traditional and nanophotonic colour technologies.
The structures of interest include diffraction
gratings, nanoaperture arrays, thin films, and
multilayers and structures that support Mie
resonances and whispering-gallery modes.

At wavelengths shorter than about 300 nm, there is a relatively large variation in the Sun’s extreme UV and x-ray output (greater than 1%), but the Earth’s atmosphere is nearly
opaque at those wavelengths (courtesy Judith Lean).

an habit of announcing new products during the events. This year is no different as the company
has announced a new Nano Family with four boards:
●
ArduinoNanoEvery powered by a Microchip ATMega4809 AVR microcontroller
●
Arduino Nano 33 IoT with secure internet connectivity thanks to a U-blox ESP32 WiFi module
and ATECC608A HW crypto chip
●
Arduino Nano 33 BLE with Bluetooth connectivity via U-blox NINA B306 module based on
Nordic Semi nRF52480 Bluetooth 5.0 chip
●
Arduino Nano 33 BLE Sense with a design similar to Nano 33 BLE but some extra on-board
sensors.
Sensors – 9-axis accelerometer, gyroscope,
and magnetometer, temperature, pressure,
humidity, light, color, gestures sensors, digital
microphone
Arduino Nano 33 BLE Sense sells for
$29.50 without headers, and $31.50 with
headers.
