Fast crystallization of solid-phase materials in liquid medium is a crucial prerequisite to achieve the aims of a number of applications for micro-, nanomanufacturing, bio-chemical sensing technology and fundamental colloidal scienceCorresponding mechanical systems for those applications are required to accommodate and take advantage of the virtue of multi-phase (liquid, gas, and solid phases) flow phenomenon to accomplish “crystallization...

The superiority of lidar compared to radiofrequency and ultrasonic solutions in terms of depth and lateral resolution has been known for decades. In recent years, both application pull such as 3D vision for robotics, rapid prototyping, selfdriving cars, and medical diagnostics, as well as technology developments such as integrated optics and tunable lasers have resulted in new activities

BPN374: Optoelectronic Tweezers (OET), Dielectrophoresis (DEP), Embryo

Justin Valley
2010

We are developing a novel technique using Optoelectronic Tweezers (OET) to quantitatively assess the morphological state and health of B6D2F1 mouse embryos. One major factor involved in successful in-vitro fertilization (IVF) is the selection of healthy embryos for implantation. A major indicator of a healthy embryo is its ability to develop quickly relative to its peers. Currently, embryos are selected by an experienced technician who uses solely qualitative observations. A method to quantitatively discern embryos which reach certain developmental stages faster than others could...

BPN397: Electrothermally-Actuated Free-Space Board-To-Board Optical Interconnect With Zero Power Hold

Jeffrey B. Chou

2010

Free-space optical interconnect using arrays of vertical-cavity surface-emitting lasers (VCSELs) and photoreceivers can significantly increase the board-to-board interconnect bandwidth, relieving the bottleneck of traditional backplane systems in computer servers. However, critical alignment errors, due to insertion variation, have prevented the deployment of such a technology. We present an adaptive free-space optical interconnect using electrothermal MEMS rotational lens scanners with zero power hold to circumvent such difficulties. Previous groups have attempted to adaptively...

Laser Chirp Linearization and Phase Noise Compensation for Frequency-modulated Continuous-wave LiDAR

Xiaosheng Zhang
2021

Microrobots can someday be used as a tool to further expand investigative capabilities– for example, archeologists could use them to research buried cities such as the one in Tiwanaku, Bolivia, or emergency response workers could send robots ahead in search-and- rescue operations. The anatomy of a microrobot can be broken down into its body, brain and power. Typically, each subsystem is fabricated using a different process, creating the need for multi-chip assembly. Microrobots in the literature are often assembled post-process using methods such as wire bonding, silver epoxy, and flip-...

Co-planar Optoelectrowetting (OEW) Device for Droplet Manipulation

Jodi Loo
2020

Lab-on-a-chip technologies have seen great advances and development over the past few decades in addressing applications such as biochemical analysis, pharmaceutical development, and point-of-care diagnostics. Miniaturization of biochemical operations performed on lab-on-a-chip platforms benefit from reduced sample, reagent and waste volumes as well as increased parallelization and automation. This enables more cost-effective operations along with higher throughput and sensitivity for faster and more efficient analysis and detection.
