Abstract
In an example, an apparatus, such as a microfluidic assembly, can include or can include using a channel including a valve seat, a valve film configured to adjust position with respect to the valve seat, and a first electrode configured to actuate the valve film electrostatically to adjust the position of the valve film to control a flow of a fluid in the channel laterally across the valve seat, the flow in a direction substantially parallel to the film.
Claims20
An apparatus, comprising:
- a channel including a valve seat;
- a valve film configured to adjust position with respect to the valve seat;
- and
- a first electrode configured to actuate the valve film electrostatically to adjust the position of the valve film to control a flow of a fluid in the channel laterally across the valve seat, the flow in a direction substantially parallel to the film.

A method, comprising:
- forming a channel including a valve seat;
- forming a valve film configured to adjust position with respect to the valve seat;
- forming a first electrode configured to actuate the valve film electrostatically to adjust the position of the valve film to control a flow of a fluid in the channel laterally across the valve seat, the flow in a direction substantially parallel to the film.
A method, comprising:
- actuating a valve film electrostatically to adjust the position of the valve film to control a flow of fluid in a channel;
- and wherein:
- the flow is in a direction substantially parallel to the valve film;
- the channel includes a valve seat;
- the valve film is configured to adjust position with respect to the valve seat;
- and
- the actuating includes using a first electrode configured to actuate the valve film electrostatically.
