Abstract A quasi-static (QS) MEMS mirror scanner with concentric vertical combs (CVC) is presented. The increase rate of overlapped area of the CVC, tends to show larger values and more uniform than that of conventional vertical combs, resulting in i

An on-axis laser Doppler vibrometer (LDV), where the direction of the incident beam is the same as the direction of the movement of the actuator, intrinsically offers an accurate dynamic measurement, although it cannot be currently applied to MEMS ac

We propose the use of a self-aligned epoxy microbridge with a metal layer for a low-cost, easy-to-make inline fiber optic chemical sensor that can sense the concentration of chemical solutions. The key component of the sensor is a cylindrical epoxy m

A new inchworm micromotor using new electrostatic in-plane twisting microactuators has been designed, fabricated and characterized for nano-resolution manipulators. The proposed twisting mechanism was implemented employing a pair of differential elec

We propose a self-aligned microlens fabricated on the sidewall of an optical fiber for a compact and high-throughput scanning optical microscopy (SNOM) application. The end face of the optical fiber is polished to have 45/spl deg/ for total internal

In this paper, frequency response (dynamic compression and recovery) is suggested as a new physical marker to differentiate between breast cancer cells (MCF7) and normal cells (MCF10A). A single cell is placed on the laminated piezoelectric actuator

A micro-plasma generator for the detection of heavy metals in the water has been fabricated and evaluated. As for the new type of a plasma source, the micro-plasma generator based on water electrode has been proposed. This type of device features sim

A FOLDV (fiber optic laser doppler vibrometer) using a 45deg-angled optical fiber with a self-aligned micro lens can be used to measure the in-plane dynamic motion of microstructure that does not allow optical access in sidewall direction. This syste

We propose a method for designing a self-aligned microlens. We have improved its fabrication by employing metallization on a 45° angled surface of the optical fiber. We designed the focal length of the microlens to be 14.0 µm, considering the dimen
