The CiS Research Institute starts developments on a miniaturized optical sensor for investigations of blood flow velocity in the skin. The sensor principle is based on the laser Doppler method. Here, elastic scattering at the moving blood components causes a shift of the light wavelength, which becomes measurable by coherent superposition with the excitation light
CiS Research Institute presents multispectral photoplethysmography sensors for applications in pain therapy at SENSOR+TEST 2015.
A mobile biofeedback system that records vital parameters of the patient measured in the external auditory canal and processes them further with the help of a smartphone app.
For precision force measurements in medical technology applications, the CiS Research Institute from Erfurt, Germany, has developed silicon strain gages (Si strain gages) with integrated measuring bridge. By using semiconductor technologies, a higher long-term stability, precision and measurement reliability is achieved compared to ductile metal strain gages
Laser light has special properties. Its beam can be guided narrowly over long distances and its spectrum is very pure. These properties are being harnessed for small sensors with micro laser illumination. The development goal is to make the length of the assembly smaller than the head of a pin (1.4 mm) and to guide the beam closer than the diameter of the pin (300 μm)
A mobile biofeedback system, which records the patient’s vital parameters measured in the external auditory canal, analyzes them with the help of a smartphone app and evaluates them individually, has been developed by the CiS Research Institute together with medical experts and industry partners

The sensor system developed contains four channels, each with an excitation LED, optical filters and detectors for measuring light transmission and fluorescence. The channels are designed in such a way that they cover wide ranges of the visible spectrum and can thus be used for the detection of many different substances
A modular technology concept enables the efficient development of optical sensors with embedded light sources, micro-optics for beam shaping or steering, optical filters and an optimised detector array
According to a study published in 2003 by the NFO World Group, around 15 million people in Germany suffer from chronic pain. An interdisciplinary team of physicians, engineers and software developers wants to support their medical treatment
To detect the need for accommodation, the so-called pupil near reflex must be measured. For this purpose, the CiS Research Institute is currently developing an optical sensor system that measures the pupil diameter and simultaneously the total brightness. From these signals, input control variables for the actuator-operated lens system are derived
