01 / Projects & Research
Real prototypes and research, each starting from a specific human need.
A bench prototype that warms IV fluid toward 37°C using three DS18B20 temperature sensors, PWM heating, and combined feedforward and PI control, with monitoring and alarms built in from the start.
Bench prototype; not clinically validated or tested against medical-device standards.
A self-built vessel that measures turbidity and dissolved solids in real time, logs data, collects floating debris, and carries targeted chemical-dispensing mechanisms. Tested on a real waterway.
Turbidity and TDS are partial indicators; open-water chemical treatment needs further environmental assessment.
Four independent prototypes: a sensor-based posture vest with feedback; a sleep-apnea vibration alert; a wearable AI sign-language translator; and a muscle-relaxation device for rehabilitation support.
Early prototypes, informally tested; no clinical evaluation or user deployment. Sign-language vocabulary is limited and was not tested with Deaf signers; muscle-relaxation effectiveness is unmeasured.
I led a six-person team studying AI-generated deepfake fraud aimed at older adults in China, combining interviews with a review of detection methods. 18-page paper, first author.
Exploratory interviews, limited in number and region; not representative.
Mechanical design and CAD for a retractable robotic arm with gravity-compensation control, built and debugged with my team.
