I adopt a human-centered perspective to design sustainable sensing and interaction systems, which form a pervasive interface to merge the digital and physical world. I believe the key for such an interface is spontaneous and smooth flow of information and energy among computers and everyday things. Thus, my previous work falls into three categories:

1. Sensing Tags. I augment everyday objects with ultra-low-power, easy-to-use, and non-intrusive wireless sensing tags, which have low expense, deployment cost, and maintenance cost.
2. Finger Wearables. I develop multi-purpose, power-efficient, and privacy-protective finger wearables, which can provide a rich, spontaneous, and consistent interaction experience.
3. Interconnection Techniques. I establish both power and information links among devices to redistribute the power, computational, and interactive resources, especially between today’s powerful on-body devices and resource-limited off-body devices.
