Emitters, detectors and LEDs for wearables

Marktech Optoelectronics has announced its dedicated offerings for wearables. The company’s standard and custom emitters and detectors, in both multi-wavelength and hybrid designs and in UV, visible, infrared, and SWIR ranges, are routinely specified within consumer- and hospital-grade flexible, stretchable and wearable devices.

Some of the most common wearable applications supported by Marktech include consumer grade fitness trackers; high-end cardiac, oxygen, and blood pressure monitors; audiological diagnostic devices, used to detect inner ear abnormalities and damage; non-invasive optical chemical sensing; and indoor/outdoor UV-level detection.

For wearable designs requiring more advanced onboard monitoring and detection capabilities, Marktech offers a number of multi-wavelength emitter-detector combinations. These combinations may be seamlessly integrated into a single package along with a multi-wavelength range detector. In addition, Marktech’s Silicon and InGaAs photodetectors may be similarly combined with its GaP Schottky UV photodiodes, creating an expanded spectral detection range of approximately 150nm to 1,750nm. Optoelectronics assemblies are available in plastic, ceramic, and glass-to-metal (hybrid) package types. A number of options are also available to effectively address specialty requirements for hermetic sealing, temperature extremes, and humid or moisture-rich environments.

In addition, Marktech high-brightness LEDs and LED emitters are routinely specified for wearable displays and remote physiological monitoring requirements. Standard LED emitters are offered in wavelengths from 280nm to 1,720nm, with expanded wavelengths by special request. These Marktech LED emitters can be further optimised for low power consumption. Such optimisations can result in increased wearable device battery life, while still maintaining required output levels. The achievement of operating currents of 2mA or less are also possible. In applications requiring the incorporation of a white LED, an assortment of colour temperature and CRI are available, as well as lower-profile direct-attach (DA) type chip packages. Please consult the Marktech R&D team for applications assistance.

All design and testing of Marktech optoelectronics components and assemblies is conducted from the company’s worldwide R&D centre in New York. There, Marktech is able to design, develop and test optoelectronics components to customer exacting standards. Each new wearables design draws upon Marktech’s own vast portfolio of related success stories and applies the acquired value-added expertise of lessons learned. Wearable optoelectronics components from Marktech may be produced in virtually any sized quantity, from prototype to OEM volumes, with competitive lead times. Marktech also has the necessary full in-house capabilities to perform complete electrical and optical characteristics testing, from die-level to finished product designs, as well as complete end-to-end examinations of related components and assemblies.
