A device for measuring a physiological parameter of a user carrying the device that includes a sensor having at least two sensor elements for detecting a sensor signal, a carrier configured to carry the sensor, and electrical contacts of the sensor elements that lead on, into or through the carrier. One or more frames carried by the carrier are formed around the sensor and/or the individual sensor elements, and an insulator material is filled between the one or more frames and the sensor and/or the sensor elements surrounded by a respective frame without covering a top surface of a respective sensor element facing away from the carrier.

Device for measuring a physiological parameter of a user

An optical analysis system and method is provided in which a sample is analyzed using a light source. An optical sensor signal is processed using a first signal processing circuit and an electrical signal, which is representative of a drive signal applied to the light source, is processed using a second signal processing circuit. The sensor signal is further processed to improve the signal to noise ratio using the processed electrical signal as a reference.

Optical analysis system and method

The present invention relates to a photoplethysmography sensor apparatus (), a photoplethysmography sensor method (), and a photoplethysmography sensor computer program product. It is proposed to measure a photoplethysmographic signal without ambient light interference. Ambient light signals are rejected by subtraction of a compensation current at the input of a transimpedance amplifier (). The compensation current is controlled via a closed loop, without interfering with the low duty cycle operation of a photoplethysmography LED ().
