Battery-free Internet-of-Things (BF-IoT), which is realized by harvesting ambient energy to
power the IoT devices, has emerged to reduce the energy consumption, and alleviate …

The past ten years have seen the rapid expansion of the field of biohybrid robotics. By
combining engineered, synthetic components with living biological materials, new robotics …

Plants cover a large fraction of the Earth's land mass despite most species having limited to
no mobility. To transport their propagules, many plants have evolved mechanisms to …

Using wind to disperse microfliers that fall like seeds and leaves can help automate large-
scale sensor deployments. Here, we present battery-free microfliers that can change shape …

Backscatter communication holds potential for ubiquitous and low-cost connectivity among
low-power IoT devices. To avoid interference between the carrier signal and the backscatter …

Vision serves as an essential sensory input for insects but consumes substantial energy
resources. The cost to support sensitive photoreceptors has led many insects to develop …

Energy-harvesting devices have enabled Internet of Things applications that were
impossible before. One core challenge of batteryless sensors that operate intermittently is …

Orthogonal frequency-division multiplexing (OFDM) has been widely used in WiFi, LTE, and
adopted in 5G. Recently, researchers have proposed multiple OFDM-based WiFi …

Backscatter communication holds potential for ubiquitous and low-cost connectivity among
low-power IoT devices. To avoid interference between the carrier signal and the backscatter …

WiFi backscatter communication has required unwanted constraints on either excitations or
receivers since its inception eight years ago. We present Chameleon, the first native WiFi …
