AquaFlux and Epsilon
AquaFlux™ evaporimeter and the Epsilon™ contact imaging system are the state of the art skin measurement technologies that were originally developed at London South Bank University and later converted into commercial instruments through the university spin-out company - Biox Systems Ltd (www.bioxsystems.com). AquaFlux™ and the Epsilon™ measure quantities such as TEWL, SSWL, hydration, perspiration, membrane integrity, wrinkles & skin topology (micro-relief).
The Epsilon™ is a contact imaging system that responds to capacitance. Its proprietary technology maps the sensor’s non-linear response onto a linear scale with a capacitance range from air to water. Its calibration ensures that every pixel in the image provides a reproducible measurement that can be interpreted in terms of hydration.
The AquaFlux is a TEWL measurement device with a unique patented technology that overcomes challenges of the closed measurement chamber through a condenser that continuously removes water vapour by converting it to ice. AquaFlux out-performs all its competitors in terms of accuracy, sensitivity, repeatability, reproducibility and versatility (supported by numerous studies available).
High Speed Ultrasound System
A next generation ultrasound imaging system is not available in the clinics yet. It is equivalent of a slow-motion camera that can capture more data than any commercially available ultrasound system. It can be used for medical and industrial applications. For example; high resolution imaging, cancer imaging, ultrasound treatment, bone imaging, pipeline inspection, flow measurements, defect detection in composite materials and several others.
UARP-II is a state-of-the-art ultrasound research imaging systems with 256 channels designed for fast acquisition times. It can acquire at a rate of 20,000 fps and has a data transfer rate of 64 GB/sec. Receiver front end has a capability of 80 MSPS with 12-Bit ADCs. Available with trigger inputs and output for synchronizing with other devices.
This equipment is the most advanced imaging system and itr is currently used following research projects; medical imaging super-resolution ultrasound, microvascular imaging, ultrasound elastography, blood flow measurements and ultrasound bone imaging.
Ultrasound Pressure Calibration
This is a specialised high precision ultrasound pressure calibration setup. It is equivalent of an underwater microphone. High-speed ultrasound system and the ultrasonic testing system are regularly calibrated using this setup. It can be used for medical and industrial applications. For example; measuring microbubble response, testing liquid composition, calibrating ultrasound imaging systems.
This calibration system consists of a needle hydrophone that can operate 1 – 25 MHz range. The sensor material is a 9 micron thick gold electroded Polyvinylidene fluoride (PVdF) film with a typical probe sensitivity of 55nV/Pa. It is mounted on a CNC system for scanning a full 3D ultrasound field.
This measurement setup is used to calibrate the medical ultrasound imaging systems for the super-resolution ultrasound, microvascular imaging and ultrasound bone imaging projects. Without this the performance of the imaging system might be compromised.
Modeling & Ultrasound Simulations
3D ultrasound wave simulations require high processing power and memory. We have the required software and the necessary processing capabilities to successfully run models. This simulation environment can be used for medical and industrial applications. For example; designing a high strength bolt (by simulating ultrasound waves in a heavy duty bolts used in bridge construction see left bottom figure) or designing new ultrasonic sensors (by estimating the ultrasound pressure and the ultrasonic field).
The simulation environment uses Matlab and specialised C scripts to simulate ultrasound wave propagation in hard and soft materials. It can perform linear and non-linear wave propagation simulations by running Field II, K-wave or Simsonic tools. It can be used to estimate harmonic generation through nonlinear propagation and shock waves. Microbubble oscillations under ultrasound excitation can be simulated.
This high-end simulation environment is used for the 3D super-resolution ultrasound, ultrasound bone imaging and needle pressure sensor for compartment syndrome projects.

Current active projects:
EPSRC grant: Modelling the MEchanics of Animal Whiskers (MMEAW)
|Total grant: £460,715||LSBU: £304,000|
MMEAW is a multidisciplinary project, lying at the interface between structural engineering, robotics and comparative animal physiology. It aims to extend our understanding and knowledge of how whiskers are adapted to their function and apply that understanding to applications in engineering.
|Reliable Technologies and Models for Verified Wireless Body-Centric Transmission and Localization (ROVER)|
|H2020- MSCA-RISE (872752): £150K||2020-2024|
The ROVER is seeking to develop novel solutions and procedures for international adaptation of complex non-invasive on-body and in-body wireless systems for healthcare devices. It enables a natural route from profound basic research to health-related applications facilitating the commercialization of wireless technology innovations for international markets. The ROVER is capable of contributing to all levels of the Research, Development and Innovation (RDI) process of new end-to-end approaches. The system architecture that the team envisions as the ultimate outcome of the four-year project is increasingly seamless, dependable, energy-efficient and secure. Our team is also capable to take into account all the features coming from 5G health vertical roadmap due to the existing research activities we have. The system architecture to be developed relies on pivotal expertise in multidisciplinary areas of engineering, physics, medicine, computer science and product development. The end to end ROVER architecture described implements non-ionizing diagnostics and monitoring augmented by secure data transfer at all levels with medicinal involvement does not currently exist. Individual as well as pivotal collaborative research and innovations are required to create user-required backward compatible systems beyond state-of-the-art.
|UWB Wearable Apparatus for Bone Fracture Imaging and Recovering Monitorin|
|H2020-MSCA-IF (793449): £180K||2018-2020|
UWB imaging has recently emerged as one of the most promising non-invasive imaging modalities of the last two decades. Its low cost, non-ionising characteristics justify the considerable interest of the scientific community. Extension of microwave imaging to bone fracture assessment is one goal of WEBOING proposal. In this contest, the design of UWB wearable apparatus for bone fracture imaging and recovering monitoring will allow to perform imaging without exposing patients to dangerous X-rays.The portable nature of the apparatus, will allows its use in site of accidents. In fact, simple microwave antennas coupled with a laptop-integrated Vector Network Analyser (VNA) are required, giving the methodology simplicity in manufacturing and a very a low cost; this aspect is even more significant if related to conventional techniques. Imaging of the bone fracture will be performed for the first time by appropriately reconstructing the electromagnetic field at UWB frequencies. Electromagnetic field reconstruction will be performed combining Modes concept and Huygens principle, which represents a new and unconventional procedure. Moreover, the same UWB antennas will also allow fracture recovering monitoring; in fact, by embedding the antennas in the plaster cast, it will be possible to perform bone imaging on periodic base without having to remove the plaster cast itself. Since the apparatus will use safe UWB rather that dangerous non-ionising radiation, examination can be repeated any time and in any condition.
