Patent number: 8111466Abstract: A microlens chip comprises a variable focus fluidic microlens and actuator. The actuator varies the pressure in a fluidic channel in the microlens chip which is coupled to an aperture opening containing the microlens. Applying an electric field to the actuator creates changes in fluid pressure in the fluidic channel, which in turn changes the radius of curvature (i.e., focal length) of the fluidic microlens.Type: GrantFiled: January 27, 2011Date of Patent: February 7, 2012Assignee: Agency for Science, Technology and ResearchInventors: Isabel Rodríguez Fernández, Peter M. Moran, Aik Hau Khaw, Saman Dharmatilleke

Publication number: 20100309560Abstract: The present invention provides a variable focus fluid lens wherein the focal length is controllable by changing the contact angle of a fluid meniscus. A liquid (20), such as water, is filled in a tubular housing (10) with an internal surface including adjacent hydrophilic (40) and hydrophobic (30) areas or regions, wherein the boundary between the hydrophilic and hydrophobic regions constrains the liquid (20) and presents a meniscus (50) having a curvature defined, in part, by the static contact angle at the boundary. When a control pressure is applied to the liquid (20), the curvature of the meniscus (50) varies as the contact angle of the liquid changes at the boundary.Type: ApplicationFiled: February 24, 2006Publication date: December 9, 2010Applicant: Agency for Science, Technology and ResearchInventors: Saman Dharmatilleke, Isabel Rodriguez Fernandez, Aik Hau Khaw
