Piezoelectric Transducers on Mars Rover | Ultra-High Performance + Reliability
Classification: Piezoelectric Actuators
Any instrument to survive the trip to and operating conditions on Mars needs to be designed to withstand the most adversary conditions.

How do Piezo Actuators Work? Direct Drive vs. Flexure Actuators: Motion, Force Gen, Positioning
Classification: Piezoelectric Actuators
https://www.pi-usa.us/en/tech-blog/re... How does a piezoelectric transducer (actuator) work? Modern Piezo actuators are based on thin piezoceramic layers manufactured in a co-fired process to form a monolithic unit. They are also called multilayer actuators, similar to multilayer ceramic capacitors. When an electric voltage is applied to the piezo actuators electrodes, the unit changes its shape, and thus displacement. Depending on the cross section of the piezo ceremic forces from hundreds to 10''s of thousands of Newtons can be generated allowing for precision positioning of heavy loads or active correction or vibration cancellation. Piezoelectric actuators are often used in applications including precision motion control, precision dispensing, force control, vibration control, nanopositioning, medical devices, etc. https://www.pi-usa.us/en/products/mic...

Wafer Stealth Dicing / Motion Control for Laser Based Semiconductor Wafer Dicing
Classification: Linear Slides and Linear Stages
The production of computer chips starts with the separation of individual dies from the semiconductor wafer. Laser dicing has many advantages over physical cutting equipment. A new and improved method of laser dicing is the so-called stealth laser dicing (SLD). This is achieved by focusing a laser below the wafer surface, which will create a modified layer within the wafer. A tape expander will later separate the chips. High precision motion and nanopositioning stages, high resolution nanofocusing devices for the laser beam and advanced software facilitate the design, setup and operation of a wafer stealth dicing system.
