Marktech Optoelectronics of Latham, New York, USA announced the introduction of multi-wavelength emitters, detectors, and LEDs for wearables. Marktech points out that its standard and custom emitters and detectors, in both multi-wavelength and hybrid designs with wavelengths in the UV, visible, infrared, and SWIR ranges, are frequently specified for consumer- and hospital-grade flexible, stretchable and wearable devices.
Some of the more common wearable applications that these Marktech products support include consumer-grade fitness trackers; high-end oxygen, cardiac, and blood pressure monitor; audiological diagnostic devices for detecting inner ear abnormalities and damage; non-invasive optical chemical sensing; and indoor/outdoor UV-level detection.
For wearable designs that need more advanced onboard monitoring and detection, Marktech offers some 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 also be combined with the company’s GaP Schottky UV photodiodes. The photodetectors combined with the photodiodes allow an expanded spectral detection range of about 150 nm to 1750 nm.
Optoelectronics assemblies come in plastic, ceramic, and glass-to-metal (hybrid) package types. Several options are also available to address specialty requirements for hermetic sealing, temperature extremes, and humid or moisture-rich environments.
Also, Marktech says its high-brightness LEDs and LED emitters are often specified for wearable displays and remote physiological monitoring devices. The firm’s standard LED emitters come in wavelengths from 280 nm to 1720 nm, with expanded wavelengths by special request.
Marktech says it can further optimize these LED emitters for low power consumption while maintaining the required output. Such optimizations can result in increased wearable device battery life. The company says that the emitters can achieve operating currents of 2 mA or less. In applications that demand a white LED, an assortment of color temperature and CRI options are available, in addition to lower-profile direct-attach (DA) type chip packages.
