This paper presents a power electronics design for the piezoelectric actuators of an insect-scale flapping-wing robot, the RoboBee. The proposed design outputs four high-voltage drive signals tailored for the two bimorph actuators of the RoboBee in a

We demonstrate a fully integrated system-on-chip (SoC) optimized for insect-scale flapping-wing pico-aerial vehicles. The SoC is able to meet the stringent weight, power, and real-time performance demands of autonomous flight for a bee-sized robot. T

This paper describes a power electronics unit (PEU) for an insect-scale flapping-wing robot. Three power saving techniques used in the actuator driver of the PEU — envelope tracking, dynamic common mode, and charge sharing — reduce power consumpt

We demonstrate a battery-powered multi-chip system optimized for insect-scale flapping wing robots that meets the tight weight limit and real-time performance demands of autonomous flight. Measured results show open-loop wing flapping driven by a pow

Small-scale, highly maneuverable, flapping-wing robotic insects have a wide range of applications, including exploration, environmental monitoring, search and rescue, and surveillance. For these small-scale robots, a piezoelectric cantilever actuator

In previous work we presented design and manufacturing rules for optimizing the energy density of piezoelectric bimorph actuators through the use of laser-induced melting, insulating edge coating, and features for rigid ground attachments to maximize

In many digital designs, multi-stage tapered buffers are needed to drive large capacitive loads. These buffers contribute a significant percentage of overall power. In this paper, we propose two novel tunable buffer designs that enable power reductio
