The current smart windows based on polymer dispersed liquid-crystal (PDLC) and electrochromes are still not cheap enough for household applications. A flat glass is clear while a frosted glass with microrough surface appears translucent by light scattering. Motivated by this optical surface scatterer, we developed an active smart window based on a soft capacitor with voltage-tunable surface roughness. This active smart window switches between clear and frosted (from 80 to 1% in-line transmittanc...

We downscale a lab-sized preform fabrication system to a benchtop miniature preform, hence short-length fiber fabrication system. The system is compact, low cost, fast and flexible as compared to standard preform fabrication processes. Using the proposed system incorporating with solution doping technique, we have successfully fabricated several ~ 1 mm thick, 40 ± 10 mm long Thulium doped silica and germania-silica preforms. The preforms were drawn to 400 µm diameter, sub-meter length low NA Thu...

Diabetic foot is one of the major complications experienced by diabetic patients. Thus, early detection and appropriate treatment can prevent traumatic outcomes such as lower limb amputation. The temperature variations on the plantar foot can be related to diabetic foot complications. Infrared thermography allows qualitative and visual documentation of temperature fluctuation in vascular tissues. This work introduces a computer aided detection (CAD) system for diabetic foot using plantar foot th...

Welding may often be perceived as a simple manufacturing process but is in fact very complex with many factors affecting quality of the welded joints. Poor welding quality is usually the technology bottleneck during development of new products. Arc welding is the most widely used welding process, but it is not suitable for welding of special alloys, dissimilar materials, or small components requiring high precision. Laser welding offers many advantages, but it is not safe to operate laser manual...

Copper based inks have been gaining interest as a potentially cheaper alternative for the conventional, market ready conductive silver inks. However, most of the current copper inks in the market have the tendency to oxidize under room conditions, leading to performance issues and thereby limiting their adoption. This technology presents a range of conductive materials, specifically copper inks, targeted at the flexible printed hybrid electronics sector. These functional materials are specifica...

Infrared (IR) spectroscopy is widely used in chemical detection and analysis owning to its superior specificity and sensitivity. Molecules can be identified/detected by their unique optical absorption characteristics. Traditionally, Fourier transform infrared (FTIR) spectrometers are used, however they are bench-top instruments typically used in controlled laboratory environments. Miniaturization of those FTIRs and making them portable for field use is very attractive for range of applications i...

Currently, glucose levels and blood core temperatures are measured by the invasive devices and methods, and no established non-invasive devices can solve this issue. We developed a sensor to measure multiple physiological parameters noninvasively, by photoacoustic technique together with advanced signal processing algorithm to further enhance reliability. Photoacoustic combines the merits of deep penetration provided by ultrasound, and high contrast provided by laser, to achieve promising measur...

A solar energy based water purification system is proposed to purify seawater or contaminated water containing heavy metal ions, undesirable chemicals, biological contaminants, suspended solids and gases, etc. The purified water can be used for human consumption (drinking water) and medical, pharmacological, chemical and industrial applications. In this system, solar energy is converted to thermal energy with a solar absorber to purify sea water or contaminated water. Compared to conventional ...
