A three-way (3-way) Micro-Electro-Mechanical Systems (MEMS)-based micro-valve device and method of fabrication for the implementation of a three-way MEMS-based micro-valve are disclosed. The micro-valve device has a wide range of applications, including medical, industrial control, aerospace, automotive, consumer electronics and products, as well as any application(s) requiring the use of three-way micro-valves for the control of fluids. The discloses three-way micro-valve device and method of fabrication that can be tailored to the requirements of a wide range of applications and fluid types, and can also use a number of different actuation methods, including actuation methods that have very small actuation pressures and energy densities even at higher fluidic pressures. This is enabled by a novel pressure-balancing scheme, wherein the fluid pressure balances the actuator mechanism so that only a small amount of actuation pressure (or force) is needed to switch the state of the actuator and device from open to closed, or closed to open.

Microfabricated fluidic circuit elements and applications

A microfabricated fluidic unidirectional valve includes a microfabricated elastomer material having a flow through channel. The microfabricated fluidic unidirectional valve also includes an elastomer flap attached to the elastomer material in the flow through channel. The elastomer flap forms a seal in the flow through channel to prevent fluid from flowing in a first direction through the flow through channel and to allow fluid flow in a second direction through the flow through channel.

ELECTRONIC DEVICE, WEARABLE DEVICE, PRESSURE REGULATOR VALVE AND METHOD FOR MANUFACTURING PRESSURE REGULATOR VALVE

An electronic device includes a housing and an internal pressure regulator valve. The internal pressure regulator valve includes a valve body of flexible material. The valve body has a valve hole and a hollow. The hollow is continuous with the valve hole and opens into the housing. Through the valve hole, gas is released to outside.

Wearable glove with a plurality of fluidic actuators and a plurality of fluidic control devices and system of use thereof

A wearable glove for interacting with virtual objects in an artificial-reality environment is described herein. The wearable glove comprises a matrix made of an elastic polymer, the matrix including a plurality of voids, each respective void (i) including at least one fluidic actuator and ii) not being fluidically coupled with a positionally adjacent void of the plurality of voids included in the matrix. The wearable glove further comprises at least one fluidic control device coupled to the at least one fluidic actuator. The at least one fluidic control device provides (i) a first fluid pressure to the at least one fluidic actuator, which causes the at least one fluidic actuator to enter a high-pressure state and (ii) a second fluid pressure to the at least one fluidic actuator, which causes the at least one fluidic actuator to enter a low-pressure state.
