Photoplethysmography-Based Blood Pressure Monitoring Could Improve Patient Outcome during Anesthesia Induction
(2022-10)During anesthesia, noncritical patients are routinely monitored via noninvasive cuff-based blood pressure (BP) monitors. Due to the noncontinuous nature of the monitoring, the BP values of the patient remain unavailable ... -
Physical Activity
(2017-11-25)We begin by briefly introducing the basics of the most frequently used sensors in nowadays wearables targeting a profiling of human physical activity: inertial, biopotential, bioimpedance, and optical sensors. The backbone ... -
Physical activity profiling: Activity-specific step counting and energy expenditure models using 3D wrist acceleration
(2015)In this paper, we present the evaluation of a new physical activity profiling system embedded in a wrist-located device. We propose a step counting and an energy expenditure (EE) method, and evaluate their accuracy against ... -
Physiological Monitoring System for High Altitude Sports
(2010-07-12)Improvement of sport performances at high altitude would require the monitoring of physiological parameters such as heart rate, SpO2, and respiration. However, commercially available devices cannot cope with peculiar ... -

Piezoelectric and structural properties of c-axis textured aluminium scandium nitride thin films up to high scandium content
(2018)Partial substitution of aluminium by scandium in the wurtzite structure of aluminium nitride (AIN) leads to a large increase of the piezc electric response by more than a factor of 2. Therefore, aluminium scandium nitride ... -
Plasmon-less Raman enhancement mechanism induced by dense networks of nanoparticles produced by femtosecond lasers
(2017)Raman spectroscopy is the workhorse for label-free analysis of molecules. Here, we show that dense self-organized networks of nanoparticles produced during femtosecond laser can lead to a strong Raman enhancement effect. -
Plasmon-less surface enhanced Raman spectra induced by self-organized networks of silica nanoparticles produced by femtosecond lasers
(2017)Raman spectroscopy is the workhorse for label-free analysis of molecules. It relies on the inelastic scattering of incoming monochromatic light impinging molecules of interest. This effect leads to a very weak emission of ... -
Plenoptic Inspection System for Automatic Quality Control of MEMS and Microsystems
(2021)Optical quality control of MEMS and microsystems is challenging as these structures are micro-scale and three dimensional. Here we lay out different optical systems that can be used for 3D optical quality control in ... -
Point of Care measurement tools for biomonitoring
(2022-09-21)The need for fully integrated and automated diagnostics solutions for human health is increasing, fueled by the widespread tendency of the industry to offer portable approaches enabled by the latest technological improvements ... -
Porous multi junction thin-film silicon solar cells for splitting
(2018)Monolithic solar water splitting devices implemented in an integrated design approach, i.e. submerged in the electrolyte, pose a significant limitation when it comes to up-scaling. The ion transport distances around the ... -
Portable Systems for Metered Dispensing of Aggressive Liquids
(2018)Precise metering in liquid dispensing applications often requires application-specific solutions due to incompatibilities of the sensor and actuator components with the dispensed liquids. Some reoccurring challenges are ... -
Postoperative ileus in an enhanced recovery pathway—a retrospective cohort study
(2017)Enhanced recovery after surgery (ERAS) protocols advocate no nasogastric tubes after colorectal surgery, but postoperative ileus (POI) remains a challenging clinical reality. The aim of this study was to assess incidence ... -
Postoperative urinary retention in colorectal surgery within an enhanced recovery pathway
(2017)Background: Enhanced recovery after surgery (ERAS) guidelines for colorectal surgery suggest routine transurethral bladder drainage with early removal to prevent urinary tract infection (UTI). The aim of this study was to ...
