Performance Assessment of a Dedicated Reflectance Pulse Oximeter in a Neonatal Intensive Care Unit
(2018)The measurement of peripheral oxygen saturation (SpO2) in neonatal intensive care units (NICUs) poses a significant challenge. Motion artifacts due to the patient’s limb motion induce many false alarms, which in turn cause ... -

Perovskite/Perovskite/Silicon Monolithic Triple-Junction Solar Cells with a Fully Textured Design
(2018)High efficiency triple-junction solar cells are currently made of III-IV semiconductors using expensive deposition methods. Perovskite/perovskite/silicon monolithic triple-junction solar cells could be a lower-cost alternative ... -
Perovskite/Silicon Tandem Solar Cells: Challenges Towards HighEfficiency in 4-Terminal and Monolithic Devices
(2017)Perovskite and silicon solar cells have recently been shown to be perfect partners for tandem devices with potentially very high efficiency at low additional costs over standard silicon cells. Here, we present the development ... -
Perovskite/Silicon Tandem Solar Cells: Marriage of Convenience or True Love Story? - An Overview
(2018)Perovskite/silicon tandem solar cells have reached efficiencies above 25% in just about three years of development, mostly driven by the rapid progress made in the perovskite solar cell research field. This review aims to ... -

Phosphorous-Doped Silicon Carbide as Front-Side Full-Area Passivating Contact for Double-Side Contacted c-Si Solar Cells
(2019)We present an electron selective passivating contact based on a tunneling SiO. capped with a phosphorous doped silicon carbide and prepared with a high-temperature thermal anneal. We investigate in detail the effects of ... -
Photo-acoustic dual-frequency comb spectroscopy
(2020-08-20)Photo-acoustic spectroscopy (PAS) is one of the most sensitive non-destructive analysis techniques for gases, fluids and solids. It can operate background-free at any wavelength and is applicable to microscopic and even ... -
Photonic chip based optical frequency comb using soliton induced Cherenkov radiation
(2015-06-27)Microresonator optical frequency combs have become an actively researched alternative way to generate optical frequency combs. Their key properties are large mode spacings and the potential for photonic integration which ... -
Photoplethysmography-Based Ambulatory Heartbeat Monitoring Embedded into a Dedicated Bracelet
(2013-09-22)Ambulatory electrocardiogram (ECG) monitors have been intensely used since half century but are still associated to clinical/ambulatory cumbersome procedures. The question of this research is the following: what is the ... -
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 ...
