The ThirdEye [Paper]
ThirdEye is a pair of smart glasses which could help people fight against myopia. It incorporates gyroscope, accelerometer, proximity and ambient light sensor in a small sensor board mounted on commercial glasses. It could recognize various scenarios in our daily life, and give alarm when the user violates given rules that may cause myopia, such as reading too close or in dimly conditions.The glasses could also log data, providing valuable information to the research of myopia. This work will be presented to EWSN'13. [PDF]
• Designed the sensor board with long-range proximity detection, ultra low power ambient light sensing, motion detection, high speed wireless connectivity via Bluetooth 2.1+EDR, FRAM non-volatile data storage and alarm; developed driver for these sensors.
• Designed task scheduling and scenario classification algorithm to detect and alarm user's misbehaviors while maximizing the batter life time.
SEPTIMU 2 [Video] [Paper]
Earphones for Continuous and Non-Intrusive Physiological and Environmental Monitoring
SEPTIMU is a novel non-intrusive physiological and environmental sensing platform which is fully embedded in a conventional earphone, works with existing smartphones, and does not require the user to change habits in any way. It's a great challenge that we have to design a specially made ear bud that integrates so many sensors in such a small enclosure: 3-axis accelerometer, gyroscope, remote IR temperature sensor, IR LED, IR photodiode and several microphones. Measuring heart rate is very useful since it could enable many interesting application such as health monitoring and mood sensing. The challenge is that we have to measure the heart rate with sensors that could be fit into the limited space of commodity ear buds while traditional ones are far too big. Inspired by the fact that the heart beat will change the density of oxygen protein in the blood which resulted in the fluctuation of the skin's ratio of absorbed IR, I proposed that we could sense the heartbeat by measuring the reflected IR intensity. By carefully design the signal processing circuit, the result was impressive. The error for measuring the heart rate is about 2~3 beats per minute when compared with medical instruments. The work is presented at SenSys'12. [PDF]
• Proposed a new way to measure hear rate by attaching IR sensor to the ear buds. It does not requires the users to change his/her habits.
• Designed the sensor board with various sensors while maintain a very tiny form factor (9mm in diameter). Assembled the sensor board into commercial ear buds with 0.1mm wires.
• Designed the base board with signal conditioning circuits and MCU to control the sensors and process the sensor data;Developed driver for the sensors.
• Designed the data structure for communication between the SEPTIMU and cellphones.

#### Past Projects

A Street Lamp Clustered-control system based on wireless sensor actuator network [Video]
There is much room to save energy by applying intelligent energy control on the street lamps. The basic idea is that if no car is detected, we could turn off or dim the lights, like the sound-control lights in the corridor. But simply turning on/off the light is not enough because we want to turn on the lamp before the arrival of the car, instead of doing so when the car is passing by, which is too late. To solve this problem, I proposed a wireless multi-hop control system: Firstly, we get the size and speed of the car by measuring the duration and interval of the reflected IR signal. Then, the sensor will transmit the speed and size information to nearby sensor nodes. The nodes will decide when to turn on the lamp according to the size and speed of the car. All the information will be converged to the sink node and displayed on the remote server. I organized a group to do the survey and built a model to test our concept. We have recorded an introductary video at here (in Chinese).
• Proposed car detection scheme by attaching a long-range reflective infrared (IR) sensor on the lamp; Designed the multi-hop message transmitting scheme;
• Designed and implemented algorithm for traffic statues detection, programmed software for sensor nodes
Multimeter for Blood Pressure, Pulse and Body Temperature [Paper]
Traditional blood pressure meter needs complicated analog signal conditioning circuits to obtain the alternating current signal from a very large direct current bias. To address this problem, I took advantage of modern signal processing technology and the powerful Cortext-M3 controller, implemented an FIR filter and envelop detecting algorithm on the MCU. The new design needs much fewer components than traditional ones with the precision, which could helps to minimize the form factor of portable multimeter. I have this project published at MACE'11. [PDF]
• Designed hardware and software for the multimeter; compared and tested different kinds of health monitoring sensors
• Designed FIR filter and envelop detecting algorithm on MCU, which do not need analog conditioning circuits; Implemented it on both MSP430 and STM32 microcontroller
