The research line focuses on advanced micro/hybrid systems that can be applicable to human beings, biological and chemistry researches. The key research interests are:
· Advanced electronics platform for small animal behavioral study. Miniaturized circuit/SoC for simultaneous extracellular electrophysiology recording and optogenetic neural manipulation is studied.
· Micro ultrasound transducer for biological imaging and measurement. New membrane structure CMUT is designed and fabricated based on MEMS technology to enhance the output ultrasonic pressure. Multi-frequency CMUT is investigated to extend the imaging capability of photoacoustic imaging.
· Intra-body Communication with study in physical layer and MAC layer and their IC implementation.
· Microprocessor with built-in multi-tasking ability for biomedical engineering applications. This can be used as a platform for ASIC development for related applications.
· Ultra-low-power energy harvesting CMOS biomedical implantable sensing chip. Single-chip energy harvesting solution with various ambient sources for low voltage operation, high efficiency and ultra-compact form factor are investigated.
· Ultra-low power biopotential interfacing circuit. Nanowatt analog signal processing and filtering is studied, focusing on nanowatt circuit design, subthreshold operation, linearity improvement and gain compensation.
· Digital microfluidic chips with software-defined intelligence. On-chip 3D structures for precise droplet splitting, fuzzy-logic and real-time feedback for precise droplet positioning, and non-DC driving voltage waveforms for higher droplet moving speed are investigated.
