Tracking health with consumer devices

What is your resting heart rate, and is your blood pressure within range?

Healthcare is becoming accessible for everyone as an integrated element of smart phones and wearables. Digitalization helps to individualize and optimize fitness levels and the monitoring of medical conditions. Devices are getting smaller, smarter and ever more accurate.

ams OSRAM brings together innovative light-emitting and optical sensor solutions for advanced fitness tracking and health monitoring applications. The variety of available devices and applied technologies have several things in common, namely the need for accurate and reliable data, optimum quality, miniaturized components and high energy efficiency.

The rise of the ‘quantified-self movement’ in consumer electronics together with the increase in demand for medical wearables to measure monitor and record vital signs – both in and out of direct medical supervision – has accelerated the demand for sensors that can be integrated into any wearable device like watches, fitness bracelets, earbuds, and even disposable stick-on patches. ams OSRAM is pioneering innovative biometric optical sensor solutions and components for fitness tracking, analysis, and health monitoring applications. The small, intelligent, and reliable optical sensors accurately measure vital signs including heart rate, temperature, and blood oxygen saturation, and can easily be integrated into any product enabling consumers and healthcare professionals to continuously monitor vital signs using non-evasive methods.

Our optical sensor solutions are designed for low energy consumption and deliver high signal quality for extreme accuracy. We work with a wide cross-section of industry partners to ensure that our products address today’s critical needs – from cardiac awareness to possible COVID-19 symptoms.

AFE (Analog Front End)

In addition to ams OSRAM’s capabilities in optical technologies, we have a full suit offering including Analog Frontends that enable the user to detect biosignals such as PPG, PTT, Blood Pressure, SpO2 and more. Our low-power design and small form factor are particularly well suited to application in earbuds, fitness bands, smartwatches, sports watches and smart patches. In these cases, board space is limited, and users look for extended, multi-day intervals between battery recharges. Thin package dimension makes ams OSRAM’S AFE particular suitable for height constrained solution.

ams AS7050 Medical and Health Sensor - Analog Frontend

The AS7050 Biosignal Sensor Analog Frontend is the next generation Vital Sign Sensor. It enables the user to detect biosignals such as photoplethysmogram (PPG), electrocardiogram (ECG) and galvanic skin resistance (GSR). PPG is the most used HRM method. It measures the pulse rate by sampling light modulated by the blood vessels, which expand and contract as blood pulses through them. ECG is the reference for any measurement of the biopotential generated by the heart. Compared to the previous ams-OSRAM biosignal sensor generation, AS7050 is a biosignal converting unit. The AS7050 provides up to 8 LED driver outputs, samples up to 6 photodiode inputs and supports external electrodes. This enables the highest flexibility for several LED and photodiode arrangements in different applications. Furthermore, the AS7050 Biosignal Sensor Analog Frontend provides 2 ADC channels for simultaneous PPG and ECG measurements and an automatic photodiode offset control. The embedded ECG analog front-end satisfies IEC 60601-2-47 requirements.The AS7050’s low-power design and small form factor are particularly well suited to application in fitness bands, smartwatches, sports watches, smart patches and earbuds. In these cases, board space is limited, and users look for extended, multi-day intervals between battery recharges. Thin package dimension makes the AS7050 suitable for height constrained solution likes earbuds.

ams AS7057 Medical and Health Sensor - Analog Frontend

The AS7057 Biosignal Sensor Analog Frontend (AFE) is the next generation Vital Sign Sensor. It enables the user to detect biosignals such as photoplethysmogram (PPG) and pulse transit time (PTT), as well as proximity. PPG is the most used HRM method. It measures the pulse rate - by sampling light modulated by the blood vessels, which expand and contract as blood pulses through them. Apart from HRM/HRV, optical Blood Pressure and SpO2 are also enabled by the two independent working photodiode inputs of the AS7057. The AS7057 is a size and performance optimized analog frontend to support space-limited applications such as in-ear vital sign monitoring.The AS7057 provides three LED driver outputs, samples up to three photodiode inputs, and supports proximity detection integrated into one of the PPG signal channels. This enables high flexibility for several LED and photodiode arrangements in different applications. Furthermore, the AS7057 Biosignal Sensor Analog Frontend provides two ADC channels for simultaneous PPG measurements and an automatic photodiode offset control.The AS7057’s low-power design and small form factor are particularly well-suited for application in earbuds, fitness bands, smartwatches, sports watches, and smart patches. In these cases, board space is limited, and users look for extended, multi-day intervals between battery recharges. A thin package dimension makes the AS7057 suitable for height-constrained solutions like earbuds.
