  1. DIRP: An Innovative Non-invasive and Continuous Personal Heat Strain Monitoring System by Photoacoustics Sensing (2014-2017): The Personal Heat Strain Monitor is a device that measures core temperature continuously and wirelessly during physical activities and at rest. This project is to develop a highly portable personal heat strain monitor which require the small sensor to be wearable/patchable and can provide accurate temperature measurement. The target device is to design a photoacoustic based sensor to meet the stringent requirements, including low power, ruggedized design, high accuracy and good penetration depth, which are not met by the current available sensors.
  2. NRF – CRP: TOWARDS THE REALITY OF 3D IMAGING AND DISPLAY: Development of the world’s first viable glasses-free television: Continuous Parallax Displays (2014-2019): In the future the majority of display devices are likely to be 3D. We have colour vision and in the latter part of the twentieth century, displays changed from monochrome to colour. We have two eyes so it is highly likely that displays will change from monoscopic to 3D as there is a well-established user preference for this. This has been promised for many years, but viewers dislike wearing special glasses to view television. 3D television will not be widely adopted until it becomes glasses-free (autostereoscopic). Another objection to 3D, whether glasses type or autostereoscopic, is the effect on viewer comfort with a high proportion reporting adverse effects; headaches, nausea etc. These effects are generally avoidable; in the hardware by ensuring correct alignment and by reducing crosstalk (ghosting, where an image is partially seen that is not intended for that particular eye), and in the content, for example by ensuring that the images do not in general appear too far in front of, or behind the screen and also by avoiding excessive jumps in depth between successive scenes. Autostereoscopic displays are currently available but these all suffer from various limitations including; viewer discomfort, loss of resolution, restricted viewing region, limited depth of field, loss of brightness, and crosstalk. Currently there are a small number of possible approaches that have the potential to provide a commercially-viable contender for glasses-free 3D television and these will be investigated in parallel in this project.
  3. DRTech: Low Power Radar System On Chip (2012-2015). In small airborne platforms with limited power, careful management of size, weight, power and cooling (SWaP-C) is critical for radar implementations. In a low-power radar system on chip (SOC) capable of pulsed de-chirp or FMCW operation, the incorporation of a waveform exciter capable of direct RF generation, receive LNA, filter, mixer and ADC directly on a chip significantly reduces the power requirements as opposed to integrating discrete components as well as reducing the size dramatically. The project is to development of a low-power radar system on chip capable of pulsed de-chirp or FMCW operation and MIMO IC-based transceiver system with coded chirp waveform generation.
  4. NMRC: Non-invasive Transdermal Electrical and Magnetic Stimulators for Pain Management (2011-2014). The project aims at studying a novel non-invasive transdermalpulsed RF and magnetic stimulator capable of relieving pain. This stimulator is potential for helping patients treat themselves at their homes. Through the project, the effects of transdermal magnetic stimulation and transdermal electrical stimulation can be monitored, and a preferable dosage, frequency, duration and current strength can be suggested.
  5. NMRC: Photo/Microwave Acoustic Imaging for Cancer Diagnosis (2011-2014). It is to develop a novel photo/microwave acoustic imaging modality and device which can offer both high contrast and high resolution imaging for non-invasive diagnosis. Potentially it can be employed as an alternative diagnostic tool for earlier cancer detection, with an underlying capability to characterize the benign and malignant tissues. The developed prototype will be applied for earlier stage breast cancer and other cancers detection.
  6. DRTech: Design of Novel SAW Correlators and Processors for Advanced Radar Systems (2010-2013). A novel SAW correlator will be designed for wideband radar pulse compression and expansion. Simulation in both system level and device level will be conducted to verify the SAW processor performance feasibility study of a delay locked loop (DLL) for wideband radar beamforming. The SAW device will be fabricated and tested for advanced radar systems.
  7. AcRF: Intelligent CMOS Cognitive Radio Transceiver for Medical Sensor Networks (2009-2013). The aim of the project is to research and explore the possible solution of cognitive radio. This work includes the system and circuit design of a cognitive radio. The target applications could be a low power sensor transceiver which co-exists with wireless transceivers which work mostly at 1.8 GHz-6GHz range. All the circuits will be implemented in a standard CMOS technology (e.g. 0.18µm) to verify the feasible of the proposed system. To meet the stringent requirement of switching and wide band operating among different wireless standards, several new techniques will be developed.

The developed components will be integrated with other modules such as data processing ASIC, Antenna, packaging etc. from partners to form a complete wireless ingestible capsule device, and functionally demonstrated in the laboratory environment. For the integrated circuit design part, we propose a new RF system architecture for thro-body communication. A CMOS low power transceiver IC chip will be designed according to the architecture.
