The second data release from the European Pulsar Timing Array IV. Implications for massive black holes, dark matter, and the early Universe

Andrii Neronov, Jia Liu, Ke Liu, Jun Wang, Jongmoon Jang

The European Pulsar Timing Array (EPTA) and Indian Pulsar Timing Array (InPTA) collaborations have measured a low-frequency common signal in the combination of their second and first data releases, respectively, with the correlation properties of a gravita ...

SU-8 cantilever with integrated pyrolyzed glass-like carbon piezoresistor

Jürgen Brugger, Giovanni Boero, Giulia Panusa, Jongmoon Jang

Glass-like carbon (GC) is a nongraphitizing material composed entirely of carbon atoms produced from selected organic polymer resins by controlled pyrolysis in an inert atmosphere. The GC properties are a combination of the properties of glass, ceramic, an ...

A Glass-Like Carbon Mems Strain Sensor

Jürgen Brugger, Giovanni Boero, Jongmoon Jang

Glass-like carbon (GC) has been widely used in micro-nano devices due to its excellent properties such as hardness, biocompatibility, and chemical inertness. In this work we investigate, for the first time, the piezoresistive behavior of GC in view of its ...

Electrochemical performance of polymer-derived SiOC and SiTiOC ceramic electrodes for artificial cardiac pacemaker applications

Jürgen Brugger, Lorenz Hagelüken, Fatemeh Navaee, Jongmoon Jang

In an implantable electrode, such as a pacemaker electrode, fibrotic tissue formation due to a foreign body reaction is an important challenge affecting the efficiency to transmit the electrical signal of the device. The chemical inertness, biocompatibilit ...

3D Printed Micro-Scaffolds Loaded by Inkjet Printing With in-Precise Amount of Drug

Jürgen Brugger, Jongmoon Jang, Christopher Chi Wai Tse, Fengyi Zheng

We propose a novel combination of two-photon polymerization (2PP) three-dimensional (3D) micro-manufacturing with drop-on-demand inkjet printing (DOD IJP) to fabricate 3D microporous scaffolds embedded with minute quantities of releasable drug. We designed ...

In Vitro Cytocompatibility Assessment of Ti-Modified, Silicon-oxycarbide-Based, Polymer-Derived, Ceramic-Implantable Electrodes under Pacing Conditions

Jürgen Brugger, Demetri Psaltis, Pierrick Guy Robert Clément, Eirini Kakkava, Giulia Panusa, Jongmoon Jang

Polymer-derived ceramics (PDC) have recently gained increased interest in the field of bioceramics. Among PDC's, carbon-rich silicon oxycarbide ceramics (SiOC) possess good combined electrical and mechanical properties. Their durability in aggressive envir ...

A 3D Microscaffold Cochlear Electrode Array for Steroid Elution

Jürgen Brugger, Joo Yeon Kim, Jongmoon Jang

In cochlear implants, the electrode insertion trauma during surgery can cause damage residual hearing. Preserving the residual hearing is an important challenge and the localized administration of drugs, such as steroids, is one of the most promising ways, ...

Characterization of a Piezoelectric AlN Beam Array in Air and Fluid for an Artificial Basilar Membrane

Jongmoon Jang

In this study, we present a piezoelectric artificial basilar membrane (ABM) composed of a 10-channel aluminum nitride beam array. Each beam varies in length from 1306 to 3194 mu m for mimicking the frequency selectivity of the cochlea. To characterize the ...
