Medical-grade vital sign monitoring

Vital sign monitoring enables the continuous measurement of key physiological parameters and supports preventive healthcare, patient monitoring and early detection of health issues. Medical-grade monitoring solutions are increasingly used in clinical environments, home healthcare and remote patient monitoring applications. 

Advanced optical emitters, sensors and integrated optical modules enable precise, non-invasive measurement of vital parameters such as pulse rate, blood oxygen saturation (SpO₂) and electrocardiogram (ECG) signals. These measurements can also support the calculation of derived parameters including blood pressure, arterial elasticity and vagal tone. 

Ongoing trends toward miniaturization, higher accuracy and increased integration are driving the development of compact and energy-efficient medical devices. ams OSRAM technologies support medical-grade vital sign monitoring through optical modules and sensing solutions designed for continuous health monitoring and long battery lifetime. 

Key benefits include: 

  • Non-invasive monitoring of pulse rate, ECG and blood oxygen levels 
  • Continuous health monitoring for preventive healthcare programs 
  • Compact and highly integrated medical-grade device designs 
  • Low-power operation for extended battery lifetime 
  • Accurate and reliable sensing for professional and consumer healthcare applications

Point-of-care diagnostics: precise automated testing, anytime, anywhere

Optical sensing technologies are enabling a new generation of point-of-care diagnostics for applications such as blood gas analysis, glucose monitoring and lateral flow testing. Advanced spectral sensing technologies provide laboratory-like measurement precision in compact and cost-effective diagnostic devices. 

Point-of-care diagnostics deliver test results directly where patients are treated, reducing turnaround times and supporting faster clinical decisions. Compared to centralized laboratory testing, these solutions improve accessibility, lower costs and enable more personalized healthcare. 

Miniaturization and chip-scale integration are key requirements for next-generation diagnostic equipment. Compact optical components allow portable and connected diagnostic devices that deliver quantitative measurements rather than simple positive or negative results, enabling earlier detection of changes in patient health status. 

ams OSRAM supports these applications with optical emitters, detectors, spectral sensing technologies, on-wafer filter technologies and micro-optics. Available as individual components or integrated optical modules, these technologies simplify the development of compact diagnostic platforms. 

Spectral emitters combined with matching detector technologies support digital diagnostics for lateral flow tests, PCR and ELISA systems, lactate measurement and next-generation chemistry analyzers. Fast, sensitive and precise optical measurements enable advanced point-of-care diagnostics and quantitative healthcare applications.

ams AS7058 High Performance Vital Sign - Analog Frontend

The AS7058 is an integrated multi-vital sign monitoring device, which provides a complete photoplethysmogram (PPG), electrocardiogram (ECG), body impedance (BioZ), and electrodermal activity (EDA). PPG measures the pulse rate or blood oxygen 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. With EDA, it is possible to measure the skin’s water content, and with BioZ, the body composition with an electrical system.

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.

OSRAM MULTILED™, SFH 7018A

The SFH 7018A & SFH 7018B feature a highly reflective QFN package for significantly increased light output. Their sophisticated 2-cavity design reduces interferences between green chip on the one hand and red and IR chip on the other hand. Furthermore, the 2 cavities enables the light sources to be optimally placed relative to their respective photodiodes. Overall this leads to higher accuracy of measurement of vital signs (e.g. heart rate, SpO2). The SFH 7018A is optimized for low Vf at high current allowing operation without voltage booster in many cases.

ams TCS3448 Spectral Color Sensor

The TCS3448 is a 14-channel highly versatile, multi-purpose spectral light sensor. It is optimized to sense spectral components of ambient light in the visible range. Such spectral information is used for camera enhancement (CCT, AWB, exposure time). The spectral response is defined by individual channels covering approximately 380 nm to 1000 nm with 11 channels centered in the visible spectrum (VIS), plus one near-infrared (NIR) and a clear channel. Applications can be assisted to allow classification of ambient light and an integrated flicker detection channel that can automatically flag ambient light flicker at 50/60 Hz as well as buffer data for externally calculating other flicker frequencies. TCS3448 integrates high-precision optical interference filters directly deposited on photodiodes which are embedded in CMOS silicon. A built-in aperture controls the light entering the sensor array to increase accuracy. A programmable digital GPIO and LED driver enable light source and trigger/sync control. Device control and spectral data access is implemented through a serial I²C 1.2 V/1.8 V interface. The device is available in an ultra-low profile package with dimensions of 3.1 mm x 2 mm x 1 mm.
