Kawasaki, S. (author), Yeh, Jia-Jun (author), Saccher, M. (author), Li, Jian (author), Dekker, R. (author)The main limitation of acoustic particle separation for microfluidic application is its low sorting efficiency. This is due to the weak coupling of surface acoustic waves (SAWs) into the microchannel. In this work, we demonstrate bulk acoustic wave (BAW) particle sorting using capacitive micromachined ultrasonic transducers (CMUTs) for the first...conference paper 2022

(author), Sarro, Pasqualina M (author)Stemming from the convergence of tissue engineering and microfluidics, organ-on-chip (OoC) technology can reproduce in vivo-like dynamic microphysiological environments for tissues in vitro. The possibility afforded by OoC devices of realistic recapitulation of tissue and organ (patho)physiology may hold the key to bridge the current...conference paper 2021

Kawasaki, S. (author), Subramaniam, Indulakshmi (author), Saccher, M. (author), Dekker, R. (author)Implantable medical devices are becoming smaller and more deeply implanted in the human body for various applications (i.e., neurostimulation, drug delivery, bone fracture monitoring). Therefore, an efficient ultrasound power transfer link is needed to charge these devices. However, this is challenging because each ultrasound transducer has...conference paper 2021

Kawasaki, S. (author), Westhoek, Y. (author), Subramaniam, I. (author), Saccher, M. (author), Dekker, R. (author)Using ultrasound to power deeply implanted biomedical devices is a promising technique due to its low attenuation in body tissue and its short wavelength that allows precise focusing of the energy. Ultrasound energy harvesting conventionally has been done using lead zirconate titanate (PZT) ultrasound transducers, which uses the piezoelectric...conference paper 2021

(author), Sarro, Pasqualina M (author), Dekker, R. (author)This work presents the first multi-well plate that allows for simultaneous mechanical stimulation and electrical monitoring of multiple in-vitro cell cultures in parallel. Each well of the plate is equipped with an Organ-on-Chip (OOC) device consisting of a stretchable micro-electrode array (MEA). For the first time, a film assisted molding ...conference paper 2018

Nanbakhsh, K. (author), Kluba, M.M. (author), Pahl, Barbara (author), Bourgeois, Florian (author), Dekker, R. (author), Serdijn, W.A. (author), Giagka, Vasiliki (author)Platinum is widely used as the electrode material for implantable devices. Owing to its high biostability and corrosion resistivity, platinum could also be used as the main metallization for tracks in active implants. Towards this goal, in this work we investigate the stability of parylene-coated Pt tracks using passive and active tests. The...conference paper 2019

Saccher, M. (author), Lolla, Sai Sandeep (author), Kawasaki, S. (author), Dekker, R. (author)Ultrasound (US) has recently gained attention for powering and communication with implantable devices due to its short wavelength and low attenuation. However, beam mis-alignments cause a sharp decrease in the amount of transferred power and quality of communication. This work investigates a telemetry protocol that relies on the difference in...conference paper 2022

Bakhshaee Babaroud, N. (author), Dekker, R. (author), Serdijn, W.A. (author), Giagka, Vasiliki (author)Parylene-C has been used as a substrate and encapsulation material for many implantable medical devices. However, to ensure the flexibility required in some applications, minimize tissue reaction, and protect parylene from degradation in vivo an additional outmost layer of polydimethylsiloxane (PDMS) is desired. In such a scenario, the...conference paper 2020

(author)Our work presents embedded high-density oxide-nitride-oxide (ONO) trench capacitors for power supply decoupling in the next generation of smart catheters. These millimeter-scale smart catheters are using a novel integration platform, Flex-to-Rigid (F2R). In the F2R platform, various functional modules are fabricated or assembled on thin silicon...conference paper 2020

(author)Vagus nerve stimulators currently on the market can treat epilepsy and depression. Recent clinical trials show the potential for vagus nerve stimulation (VNS) to treat epilepsy, autoimmune disease, and traumatic brain injury. As we explore the benefits of VNS, it is expected that more possibilities for a new treatment will emerge in the future....conference paper 2019

Dekker, Florine W. (author), Erkin, Z.

Dekker, S. (author)This study supports strategic planning of a node in a transportation network. It contributes to this by the development of a methodology for planning of port capacity in which port-commercial and public interests are integrated. The focus is the reaction of a single port on a change in the transportation network. A scenario for such change,...doctoral thesis 2005
