Ultra Resolution Actuator

Which kind of bio-instrument need a piezo actuator (ultra-precision-positioning)?

Piezo actuator can be controlled easily to afford 1nm resolution，and can afford very high force, Such actuator could be used in the positioning of cells or manipulations on a cell using glass needles.
But i haven't used any bioinstruments, so i don't know where the Piezo actuator can exaclty be use? or where could it potential be used in bioinstrument or other fields? thanks you

Piezo actuators are commonly used in microscope positioner stages, and generally in micropositioning stages. Some nanoindenters use them. Atomic force microscopes use them. And so on.

Actuator $70.1 High Quality Content by WIKIPEDIA articles An actuator is a mechanical device for moving or controlling a mechanism or system. It takes energy, usually transported by air, electric current, or liquid, and converts that into some kind of motion.The efficiency of an actuator is a standard tool used to calculate or estimate the usefulness of any actuating mechanism. It is a dimensionless quantity which is generally lower than 1 expressing the energy conversion factor. For better explanation see Thermodynamic efficiency. Most of the wasted energy (due to friction, magnetic losses, eddy currents, whatever) is thermally dissipated.

As a passionate photographer once (the last 20 + years I used a Minolta XD7 bought second hand), used to develop and print their own B & W printer, I was very slow to move into the digital fold. When I did, I felt like family favorite point + shoot compact, and fully expandable DSLR? So my attention was drawn to a new type of camera - the so-called "bridge cameras". After reading around, and research sites, I finally settled on this one. I used it for several months, so it's time to give their opinion. 

What are the benefits? Well, the fact of all: 

* The optical quality (with a reserve that Leica lens can not provide more than 27 mm, 486 mm zoom lens, the same as a small zoom or fixed). 
* Zoom range 
* Metering and exposure 
* Flexibility 
* A variety of options 
* Anti-shake software 
* Intelligent Auto (with the disclaimer that it is sometimes better pictures are available in P, or otherwise) 
* Superficiality 

There are one or two niggles: 

* Horizontal viewing electronic viewfinder is not the same as the optical viewfinder, but you get used to it 
* Zoom controls hypersensitive, which makes it difficult to push minor changes 
* I was told that the noise factor of 800 ASA or more, but this means little light, where the noise is always a problem 

You can see that the images are very few "soft" relative to a fixed lens or zoom a lot less (visible in a glass). It is inevitable: every zoom lens has a range of optical compromises, and this applies to all levels and types of camera phones. However, I found out that the application of Unsharp Mask in Photoshop at a rate of [50% radius 0.5 pixels: 0] threshold once or twice at most, brought a freshness to perfection. 

Although I still use the video, nor the manual settings (I had on Intelligent Auto most of the time), I was more than satisfied with the images I have. And is related to its findings on SLR manual focus optics very well. There are three things that I regret, that the only DSLR to me, the large additional amount: 
Before No Hot or external flash socket 
According to N-field 
Third an easy way to add filters, for example, polarizing 

Zoom range is impressive. When I tried a digital zoom closer blackbird on the lawn, which actually gave me 1000mm - anti-shake mechanism has allowed me to get this shot without the veil, and although there were some signs of poor images can not "spoil the final image. So if you need specialized lenses, such as fish-eye or a vertical displacement, this camera enough for 99% of situations. 

It is not a DSLR. But the price of weight, you will be hard to find one better. I do not regret my choice at the moment. And "rekindled my enthusiasm for photography.

Product Description

Manufacturer's Description

Hybrid Super Zoom Camera FZ38 - From 18x Optical Zoom to 27mm Wide-angle for both Still and HD Motion Pictures.

The DMC-FZ38 can record HD movie of 720P in AVCHD Lite. And a stereo microphone, featuring Dolby Digital Stereo Creator, records high quality audio. Just press the Motion Picture Button, and shooting begins. In the Creative Movie Mode, the shutter speed and aperture can be adjusted. The iA Mode can also be activated in motion picture recording. When the DMC-FZ38 is connected to a Panasonic VIERA via an optional mini HDMI cable, the TV's remote control unit can be used to enjoy playing back with greater convenience.

The DMC-FZ38 features a 27mm wide-angle 18x optical zoom f/2.8-4.4 LEICA DC VARIO-ELMARIT lens in a compact body (35mm equivalent: 27-486mm). The lens unit comprises 11 elements in 8 groups, with 2 ED lenses and 3 aspherical lenses, including a dual-sided aspherical meniscus lens. The powerful 18x zoom can also be used in motion picture recording. Furthermore, in 3-megapixel resolution, the Extra Optical Zoom function provides additional magnification, extending the zoom power to 35.2x (35mm film camera equivalent: 950mm).

POWER O.I.S. is about twice as effective as MEGA O.I.S. at reducing low-frequency vibration-caused blur when pressing the shutter button or shooting with a slow shutter speed. So you can take beautiful night shots without blurring. Activating POWER O.I.S., Intelligent ISO Control, Face Detection AF/AE with Face Recognition, Intelligent Scene Selector, Intelligent Exposure and AF Tracking, the camera does all the work in the iA Mode. Face Recognition function recognizes registered persons' faces and optimizes the focus and exposure settings.

To realize the ultra high-speed AF, a number of re-engineering and improvements are made including the adaptation of higher-speed actuator, the optimization of algorism and the parallelization of software processing element. The result is ultra high speed yet accurate AF performance for users to enjoy the airy shooting that has experienced never before. The DMC-FZ38 also replaced its linear program processing with parallel processing to achieve an ultra high-speed start-up of 1.2 seconds, a remarkable 20% decrease from previous model (FZ28).

The joystick gives the DMC-FZ38 its precise, full manual operation. Simply move the joystick vertically or horizontally to adjust the shutter speed, aperture or focus during manual focus. In addition, easy manual operation is possible with the DMC-FZ38. My Color Mode makes it easy to customize color effects to match your favor. The Advanced Scene Mode lets you quickly set the frequently used Portrait, Scenery, Sports, Night Portrait, or Close-up Modes with the mode dial. And you can adjust the aperture or shutter speed in each Creative Mode.
