Photodiode SFH 2440 L from Osram Opto Semiconductors enables fitness sensors to be made extremely thin. To save on mounting height it can be flush mounted in the board. Its spectral sensitivity – high in the green range and extremely low in the infrared range – has been designed specifically for heart rate measurements. Picture: Osram Photodiode SFH 2440 L from Osram Opto Semiconductors saves on mounting height in the design of heart rate sensors. It can be flush-mounted on the printed circuit board (PCB), with longer leads ensuring secure mounting and reliable solder points. The component also features spectral sensitivity specially designed for measuring heart rate.

Sunnyvale, CA, The SFH 7051 from Osram Opto Semiconductors is an integrated optical sensor specially designed for heart rate monitoring. This component is used in fitness trackers, smart watches and other wearables. The new sensor consumes very little power, maximizing battery life and reliability.

The SFH 7051 consists of a large-format photodiode and three green LEDs with a wavelength of 530 nanometers (nm). It is used for monitoring heart rate by measuring the volume of blood passing through blood vessels. It works by shining light on the surface of the skin. Different amounts of this light are absorbed by blood and the surrounding tissue. The light not absorbed is reflected to the detector. With its green emission spectrum, the SFH 7051 is ideal for measuring pulse rate at the wrist. [Continue reading →]

With the new SFH 4715AS and SFH 4716AS, Osram Opto Semiconductors has increased the output of its IR Oslon Black family for the second time in six months. This has been achieved by combining the latest chip design with an optimized package and Nanostack technology, in which each chip has two emission centers. Depending on the type of external optics and the particular application, the infrared light emitting diodes (IREDs) can provide illumination over a distance of more than 100 meters (109.36 yards), which makes them even better light sources for many camera-based applications.

Thanks to their high optical output of 1.37 watts (W) at 1 ampere (A), the new IR Oslon Black Stack components are the most powerful infrared light emitting diodes (IREDs) yet from Osram Opto Semiconductors. The reasons for the increase in output of over 70 percent compared with the standard version include the use of the latest generation of chips, an optimized package design and, most importantly, Nanostack technology, which means that each chip has two emission centers arranged one above the other.

Thanks to a new package, Osram Opto Semiconductors reduces the length of its large-area photodiodes by about 20 percent. The first product from this series is the IR Topled D5140 which has been optimized for the detection of visible light. Picture: Osram The Topled D5140 photodiode allows more compact sensors to be produced for heart rate monitoring. Thanks to the spectral sensitivity adapted to visible light, the component enables very precise measurements. Picture: Osram Sunnyvale, CA, November 29, 2016

Santa Clara, CA – Leading LCD supplier Tianma NLT America is introducing a new touch screen technology developed by NLT Technologies, Ltd. The company’s new 8.4-inch XGA is an amorphous-silicon thin-film-transistor (TFT) liquid crystal display (LCD) module with a "Wet & Glove" PCAP (projected capacitive) touch sensor bonded to the front. This enables operation even when the screen is wet and/or the operator is wearing gloves. It provides dry screen tracking, water buildup tracking and single glove operation, even in a wet environment. It can also be used with medical grade defibrillator gel and ultrasound gel.

PCAP touch panels are being adopted in a rapidly expanding range of industrial equipment for the superior features they provide, such as flush surface designs, multi-touch functionality and gesture operation. This trend is particularly notable in display-based devices for use in special environments – such as outdoor equipment or medical devices or marine appliances, for example – where the touch panel could easily get wet or have medicines and other liquids spilled on it, and might also need to be operated by someone wearing gloves. However, these conditions would pose a problem for the position detection method used in conventional PCAP touch panels, which cannot function properly when used by a gloved user or while the screen is wet.[Continue reading →]
