Power index of the inspiratory flow signal as a predictor of weaning in intensive care units.
International Conference of the IEEE Engineerin... 2014:78 (2014) PMID 25569901We propose an extubation index based on the power of the respiratory flow signal (Pi). A total of 132 patients on weaning trials were studied: 94 patients with successful trials (group S) and 38 patients who failed to maintain spontaneous breathing and were reconnected (group F). The respiratory flo...
Optic disc and macula detection in fundus images by means of template matching.
International Conference of the IEEE Engineerin... 2014:134 (2014) PMID 25569915Our aim is to propose a fairly easy method for detecting both features jointly. This is achieved by first correcting in homogenous luminosity using a polynomial approximation of the background of the images. Secondly, the use of the cross-correlation in the frequency domain between the images and a...
An autoregulation unit for enabling adaptive control of sensorized left ventricular assist device.
International Conference of the IEEE Engineerin... 2014:278 (2014) PMID 25569951This paper describes an integrated system for facing heart failures (HF) in an innovative way. Existing left ventricular assist devices (LVAD or VAD) are usually devoted to blood pumping without the possibility to adapt the speed to patient conditions during everyday activities. This is essentially...
Development of a coordinated controller for robot-assisted shape memory alloy actuated needle for prostate brachytherapy.
International Conference of the IEEE Engineerin... 2014:357 (2014) PMID 25569971This paper deals with the development of a coordinated control system for a robot and robot-driven shape memory alloy (SMA) actuated needle to follow a curvilinear path for percutaneous intervention. The robot driving the needle is considered as the outer loop and the non-linear SMA actuated flexibl...
Printable and transparent micro-electrocorticography (μECoG) for optogenetic applications.
International Conference of the IEEE Engineerin... 2014:482 (2014) PMID 25570001We propose a printable transparent μECoG electrode for optogenetic applications by using ultrasonic microfluid printing technique. The device is based on poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) as a conductive polymer, polydimethylsiloxane (PDMS) as an insulating polyme...
A piezoelectric energy-harvesting shoe system for podiatric sensing.
International Conference of the IEEE Engineerin... 2014:622 (2014) PMID 25570036This paper provides an energy-harvesting, shoe-mounted system for medical sensing using piezoelectric transducers for generating power. The electronics are integrated inside a conventional consumer shoe, measuring the pressure of the wearer's foot exerted on the sole at six locations. The electronic...
Implanted electronic siren to alarm for bladder full with urine.
International Conference of the IEEE Engineerin... 2014:630 (2014) PMID 25570038A Device to detect for the bladder which is full with urine is designed. The device can measure bladder pressure. The pressure signals are processed. When the pressure exceeds 40cm water column, Pressure signal exceeds a fixed voltage. At the same time, Oscillator sends a signal and the signal trans...
A stochastic modelling framework for the reconstruction of cardiovascular signals.
International Conference of the IEEE Engineerin... 2014:676 (2014) PMID 25570049We propose a general model-based methodology able to reconstruct missing or artifacted signal intervals in cardiovascular monitoring applications. The proposed model consists of independent stages which provide high flexibility to incorporate signals of different nature in terms of shape, cross-corr...
High correlation of double Debye model parameters in skin cancer detection.
International Conference of the IEEE Engineerin... 2014:718 (2014) PMID 25570059Our positive outcomes support further steps to clinical application of terahertz imaging in skin cancer delineation....
Complex micropatterning of proteins within microfluidic channels.
International Conference of the IEEE Engineerin... 2014:782 (2014) PMID 25570075We developed a new method to integrate microfluidics and protein micropatterning by attaching poly(dimethylsiloxane) (PDMS) microfluidic channels to bio-friendly photoresist films via poly(dopamine) (PDA) adhesive. A bio-friendly photoresist poly(2,2-dimethoxy nitrobenzyl methacrylate-r-methyl metha...
