On timing-optimized SiPMs for Cherenkov detection to boost low cost time-of-flight PET
Objective.Recent SiPM developments and improved front-end electronics have opened new doors in TOF-PET with a focus on prompt photon detection. For instance, the relatively high Cherenkov yield of bismuth-germanate (BGO) upon 511 keV gamma interaction has triggered a lot of interest, especially for its use in total body positron emission tomography...
Closed-Loop Split-Phase Control Applied to the Symmetric Dual Inductor Hybrid (SDIH) Converter
Predicting supercooling of phase change materials in arbitrarily varying conditions
Phase change materials are promising for thermal energy storage; however, one major bottleneck for their practical implementation is their unclear supercooling behaviors. In this work, we introduce a framework to predict the degree of supercooling for a phase change material subject to arbitrary geometrical and thermal conditions by analyzing the p...

Effect of posterior cruciate ligament on knee pressure and gap measured by an electronic sensor during total knee arthro...
Published in Journal of orthopaedic surgery and research
The purpose of this study was to evaluate the change in posterior cruciate ligament (PCL) tension by directly measuring the pressure changes in the knee joint when the ligament was released or resected during total knee arthroplasty. We prospectively analyzed 54 patients who underwent primary total knee arthroplasty (67 knees) from October 2019 to ...
Responsive materials and mechanisms as thermal safety systems for skin-interfaced electronic devices.
...
Soft, wireless physiological sensors that gently adhere to the skin are capable of continuous clinical-grade health monitoring in hospital and/or home settings, of particular value to critically ill infants and other vulnerable patients, but they present risks for injury upon thermal failure. This paper introduces an active materials approach that ...
Using augmented reality to cue obstacles for people with low vision.
Detecting and avoiding obstacles while navigating can pose a challenge for people with low vision, but augmented reality (AR) has the potential to assist by enhancing obstacle visibility. Perceptual and user experience research is needed to understand how to craft effective AR visuals for this purpose. We developed a prototype AR application capabl...
Refroidissement radiatif des cellules et modules solaires par structuration de surface
Les cellules et modules photovoltaïques s’échauffent considérablement en conditions réelles de fonctionnement, ce qui est néfaste pour leur rendement de conversion et leur durée de vie. Pourtant, les aspects thermiques sont encore peu considérés, voire complètement ignorés lors de la conception des dispositifs photovoltaïques. Dans ce contexte, l'o...
