Current projects

EWAM (Enabling Widespread Ambulatory Monitoring for improved pregnancy outcome)
SponsorSTW project
DurationStart 12-09-2016, End 11-09-2020
PhD studentYijing Zhang
SupervisorPieter Harpe, Eugenio Cantatore
DescriptionHigh-risk pregnancies are on the rise because of the progressively higher age at which women get pregnant. For such pregnancies, continuous assessment of fetal wellbeing is critical to reduce fetal mortality and morbidity rates. Unfortunately reliable continuous assessment is currently not feasible, even in clinical settings. In this project we aim at a breakthrough towards reliable continuous pregnancy monitoring in ambulatory settings, by strongly improving the unobtrusiveness and user-friendliness of the sensors, by increasing signal quality, and by exploiting supplementary information to improve diagnostic quality. Provision of reliable, continuous signals can not only improve perinatal outcome, but will also pave the way for home monitoring of high-risk pregnancies, supervised from the hospital. This will provide opportunities to high-risk pregnant mothers to remain with their family and address the problem of increasing healthcare costs for hospitalization.
SponsorH2020 project
DurationStart 01-10-2015, End 31-09-2019

DescriptionPhoenix is a European H2020 project in FET-Open, a scheme for Future Emerging Technologies and cooperation projects for advanced and paradigm-changing innovation. Humans have been exploring the world from the depths of the oceans to the edges of the universe. Yet many environments remain inaccessible, even to modern cutting-edge technology. Therefore problems like exploring the status of waste water under the Fukushima reactor, or discover suitable sites for underground CO2 storage remain unsolved. Our aim is to investigate a new line of technology that will enable the exploration of difficult-to-access environments exploiting a risky, highly-novel approach called Phoenix.

Completed projects

SEBAN (Body Area Networks)
SponsorSTW project
DurationStart 01-01-2011, End 30-12-2014
PhD studentShuang Song
SupervisorEugenio Cantatore
DescriptionThe SEBAN STW project aims at developing the methods and technologies that are needed for a low power, non-invasive, reliable body area networks, applied to continuous mobile monitoring of the fetus throughout the pregnancy at home. The focus is to conserve energy by optimal integration and cooperation between frontend, data converters and DSP.
Premiss: Power reduced monolithic sensor systems
SponsorSTW project
DurationStart 01-05-2010, End 31/07/2014
PhD studentHao Gao
SupervisorMarion Matters - Kammerer
DescriptionPREMISS aims at the realization of autonomous, battery-less wireless sensors. The miniaturization and cost reduction is taken to such an extreme that applying these sensors during construction together with other building materials (plaster, wall paper) becomes more attractive than individually placing and configuring each node. The foreseen first application of the resulting “smart wall” is in flexible sensing & control of lighting, temperature, etc. in a room. These nodes require a fundamentally different approach to the underlying architecture, power handling and radio technology. We extend the smart dust vision, by realizing a monolithic wireless sensor, without any external components. This not only means the omission of oscillator crystals, discrete components, but also the design without soldered connections, hence without battery, antenna, and external sensor.
Deep Brain Stimulation

This project models the effects of electrical stimulation onto tissue and develops architectures for new recording and stimulating systems used for Deep Brain Stimulation.

Non-invasive wearable chest based optical sensor for blood oxygen saturation monitoring
SponsorHolst Center (IMEC-NL)
DurationStart 01-09-2014, End 30-08-2015
PDeng studentNenad Cabrillo
SupervisorsMarion Matters – Kammerer (TU/e), Rick van de Wiel (Holst center)

Blood oxygen saturation is one of the primary patient health indicators. It is usually measured with pulse oximeters. These devices limit the motion range of the patient because of the cables needed for the probe. Having a wearable pulse oximeter would benefit patients in a clinical environment, but also open the door to home healthcare applications. Goal of this PDEng project is to develop an optical sensing circuit that will be able to continuously and non-invasively estimate oxygen saturation at the chest. An existing chest based sensory system developed and owned by Holst Centre is going to serve as a base on top of which optical sensing functionality will be added.
