R KANNAN, Shirley (author)
Organs-on-Chips (OoCs) are micro-engineered devices in which small samples of human-organ tissue are cultured on the substrate. A chip is designed in such a way that it can emulate the in-vivo physiological environment for disease modeling and drug screening. OoC technology can be incorporated into the drug development process from early drug...

Metal oxide nanoparticle gas sensors showpromise due to their high sensitivity towards a wide range of gases, low costs, and low complexity. Particle sizes at nanometers offer a high surface-to-volume ratio which provides more areas on the surface where reactions can occur. This work presents the application of spark ablated nanoparticles on...

Distributing power and data around a garment is a common problem in sensor enabled e-textiles, as connecting separate electronic subsystems together using connectors and wires has proven to be unreliable and cumbersome. In this work a solution is presented that will eliminate the connectors by using two pairs of short-range wireless inductive...

Son, Dongjin (author)
In this work, a SPAD-based LiDAR system is studied. In particular, the system employs a direct time-of-flight (dToF) method to reconstruct a target-reflected pulses using histogram, from which the distance to the target is estimated. More particularly, a time correlated single photon counting (TCSPC) method has been used to record the flight...

This report presents a proof-of-concept for a sensor measuring the ionic concentrations in sweat using cyclic voltammetry. Development is focused on feasibility of the sensor. Theoretical evaluations of voltammetry as a working principle and its physical and electrochemical foundations are guiding principles of the design. The sensor is then...

Particle sorting is an important step in many biological and biomedical techniques. One sorting technique that has received a lot of attention is based on acoustophoresis. Manipulating cells with acoustic forces allows for a sorting method based on physical properties in a non-invasive, label-free, and biocompatible manner. To date, acoustic...

Silicon-based MEMS technology has been the standard for developing 2D and 3D<br/>micro-structures for many years. There are 2 main classifications of MEMS manufacturing technologies, viz. bulk micro-machining, and surface micro-machining.<br/>These techniques have its own set of drawbacks. Bulk micro-machining affects the structural integrity of...

Currently, preclinical drug testing and disease modelling are based on static cell cultures and animal models that often fail at predicting the human pathophysiology. Alternatively, Organ-on-Chips (OoCs), dynamic microphysiological platforms, can be employed to recapitulate organ functions and mimic the cell's microphysiological environment....

Implantable medical devices (IMDs) such as cardiac pacemakers, cochlear implants, and neurostimulators improve millions of people’s lives every day. Over the years, IMDs have significantly improved in function, increased in lifetime, and decreased in size. However, further miniaturisation is limited by the batteries used to power these devices,...
