Smart Digital Systems / Embedded Systems
Welcome to Dr Wahid's MPP Lab. The lab is equipped with many state-of-the-art embedded system and FPGA development boards, bio-sensors and video processing boards with many tools and software. We also have Pillcam and Mirocam capsule endoscopy systems and Equivita body monitoring systems integrated with many physiological sensors. Thanks to the research funding from our sponsors.
