A microfluidic valve can include a substrate having a microfluidic channel formed in the substrate. A sealing layer can be over the microfluidic channel. A flexible blister layer can be over the sealing layer. The flexible blister layer can include a blister formed as a distended portion with a blister volume between the flexible blister layer and the sealing layer. The microfluidic valve can be actuatable by puncturing the sealing layer by pressing on the blister. Actuating the microfluidic valve can either allow fluid to flow through the microfluidic channel or block fluid from flowing through the microfluidic channel.

Microfluidic valves

A spectrophotometer includes a plurality of sensor elements arranged together, each sensor element including a filter; a light sensor optically coupled with an output of the filter; and a barrier that surrounds the filter and light sensor and a space between the filter and light sensor. For each sensor element, the barrier blocks light that has not passed through the filter from reaching the light sensor including such that light from one sensor element is not detected by another of the sensor elements.

Spectrophotometer

An electrostatic liquid-ejection actuation mechanism includes a membrane, a frame, and one or more deformable beams. The frame has two sides and a number of cross members that are non-parallel to the two sides. The two sides and the cross members define one or more areas individually corresponding to one or more liquid chambers. The deformable beams are disposed between the membrane and the frame. The deformable beams individually correspond to the liquid chambers, and define a number of slits. Each slit is adjacent to one of the two sides of the frame. The deformable beams have a width that is less than a width of the liquid chambers, due at least to the slits.

Electrostatic liquid-ejection actuation mechanism

Systems, methodologies, and other embodiments associated with a micro-electrical-mechanical system (MEMS) Fabry-Perot interferometric device (FPID) are described. Fabricating a MEMS FPID may include fabricating a pixel plate and a reflector plate so a Fabry-Perot cavity is defined therebetween. Fabrication may include producing a capacitor plate that facilitates electrostatically moving the pixel plate. Fabrication may include producing electrical connections between plates and producing circuitry to control plate voltages to facilitate creating an electrostatic force between plates. The MEMS FPID may include stops fabricated from a conductive material and circuitry for maintaining the stops and plates at an electrical potential that will yield a zero electric field contact event.

A micro-electromechanical systems (MEMS) device includes bottom and top capacitive plates, such that a capacitor is definable therebetween. A mechanism is electrostatically movably disposed between the bottom and top capacitive plates. One or more flexures are movably disposed between the bottom capacitive plate and the mechanism, and having distance stops between the bottom capacitive plate and the mechanism corresponding to maximum downward movement. The MEMS device includes one or more electrodes of the bottom capacitive plate corresponding to the flexures. Energizing different of the electrodes causes the flexures to move to different of the distance stops, causing the mechanism to move to different positions between the bottom and top capacitive plates.
