Fully Compliant Tensural Bistable Mechanisms (FTBM) with On-Chip Thermal Actuation
<p>The Fully compliant Tensural Bistable Mechanism (FTBM) class is introduced. The class consists of fully compliant linear bistable mechanisms that achieve much of their displacement and bistable behavior through tension loading of compliant segments. Multiple topologies of designs arising from …

Identification of Macro- and Micro-Compliant Mechanism Configurations Resulting in Bistable Behavior
… of several mechanism classes which result in bistable behavior. Bistable mechanisms have use in many applications, such as switches, clasps, closures, hinges, and so on. A powerful method for the design of such mechanisms would allow the realization of working designs much more easily than has …

BISTABLE STRUCTURES ENABLE PASSIVE TRANSITIONS IN MOBILE ROBOTS
… thesis, we investigate robotic applications of bistable mechanisms, mechanical structures that exhibit two stable static equilibria, to enable passive actuation and locking for systems with discrete task modes. More specifically, the main theoretical contribution of this thesis is a method for …

A Self-Retracting Fully-Compliant Bistable Micromechanism
… a class of Self-Retracting Fully-compliant Bistable Micromechanisms (SRFBM). Fully-compliant mechanisms are needed to overcome the inherent limitations of microfabricated pin joints, especially in bistable mechanisms. The elimination of the clearances associated with pin joints will allow …

Piezoresistive Sensing of Bistable Micro Mechansim State
… the feasibility of on-chip sensing of bistable mechanism state using the piezoresistive properties of polysilicon, thus eliminating the need for electrical contacts. Changes in position are detected by observing changes in resistance across the mechanism. Sensing the state of bistable …

Concept development for lightweight binary-actuated robotic devices, with application to space systems
… of this research is to integrate compliant bistable mechanisms with large numbers of binary-actuated embedded smart materials. Compliant mechanisms are lightweight and robust. Binary actuation is the idea of using an actuator in a discrete on/off manner rather than in a continuous manner. A …

A Compliant Threshold Acceleration Sensor Integrated with Radio Frequency Identifiable Tags
Fully compliant bistable mechanisms have been proposed to be used as threshold accelerometers. The advantages to using these devices are that they require no external power to operate and maintain their sensing state. Using this characteristic the devices can be integrated with passive radio …
