Integrated Wireless Power, Data Communication, and Thermal Sensing System for Autonomous Multisite Brain Implants
Implanted medical devices (IMDs) have been widely developed to support the monitoring and recording of biological data inside the body or brain. Wirelessly powered IMDs, a subset of implantable electronics, have been proposed to eliminate the limitations r ...
EPFL2024A 0.14-nJ/b 200-Mb/s 2.7-3.5-GHz Quasi-Balanced FSK Transceiver With PLL-Based Modulation and Sideband Energy Detection
This paper describes a balanced frequency shift keying (FSK) modulation, namely quasi-balanced FSK (QB-FSK), for energy-efficient high-data-rate communication. Not suffering from data-pattern dependency, the proposed modulation method enables frequency mod ...
Piscataway2024Active Power Decoupling for Single-Phase Input-Series-Output-Parallel Solid-State Transformers
Drazen Dujic, Andrea Cervone, Tianyu Wei
Solid-state transformers with input-series outputparallel structures are being considered for a variety of applications requiring MVAC to LVDC conversion. Due to the singlephase AC/DC conversion at the input side, all floating cells of the solid-state tran ...
2024Power Aware Placement of On-Chip Voltage Regulators
In traditional power delivery networks, the on-chip supply voltage is provided by board-level converters. Due to the significant distance between the converter and the load, variations in the load current are not effectively managed, producing a significan ...
Piscataway2024Integrated Electronics for Deep Implants to Remotely Monitor Hemodynamics
The integration of technology in the medical field has greatly improved accuracy in diagnoses, thus leading to more effective treatments. Wearable and implantable medical devices offer great potential for remote patient monitoring, particularly for heart f ...
EPFL2023Miniaturised, Wireless and Distributed Neural Interface Toward Cortical Visual Prosthesis
Over the last decades, implantable neural interfaces have been extensively explored and effectively deployed to address neurological and mental health disorders. The existing solutions present several limitations. Firstly, the physical size of the implanta ...
EPFL2023Gate unit for a gate-commutated thyristor and integrated gate-commutated thyristor
The invention relates to a gate unit (22) for controlling a gate commutated thyristor (21), comprising: - a voltage selector (26) for selectively applying a high supply potential (Vpos), a middle supply potential (Vmid), and a low supply potential (Vneg); ...
2023Radiation Performance of Antennas Implanted in Small Animals for Neuroengineering
Anja Skrivervik, Stéphanie Lacour, Zvonimir Sipus, Mingxiang Gao, Kangling Wu
Wireless data communication could improve the performance and reliability of biomedical implants used in fundamental neuroscience research by removing infection-prone transcutaneous cabling. The small size of common research animals like mice and rodents, ...
IEEE2023Fractal Analysis in Pulmonary CT Images of COVID-19-Infected Patients
In this paper, we propose to quantitatively compare the loss of human lung health under the influence of the illness with COVID-19, based on the fractal-analysis interpretation of the chest-pulmonary CT pictures, in the case of small datasets, which are us ...
MDPI2023Architecture for integrated RF photonic downconversion of electronic signals
Electronic analog to digital converters (ADCs) are run-ning up against the well-known bit depth versus bandwidth trade off. Towards this end, radio frequency (RF) photonic-enhanced ADCs have been the subject of interest for some time. Optical frequency com ...
