Teledyne DALSA s Semiconductor Foundry, a division of Teledyne Technologies, announced today the availability of its DH0485A Electrostatic Actuator High Voltage IC.
New Electrostatic Actuator High Voltage Integrated Circuits - Using proprietary High Voltage CMOS/DMOS technology, the DH9685AB, a 240V, 96-Channel, Precision High Voltage Programmable 16-bit DAC with Sample & Hold is designed for next-generation, high density, small footprint, low power systems using MEMS or MOEMS activation with electrostatic forces.
The company said that at the Photonix Expo & Conference it will highlight: new electrostatic actuator high voltage integrated circuits, including the DH9685AB, a 240V, 96-channel, precision high voltage programmable 16-bit DAC with Sample & Hold and the DH9665A, 96-channel, high voltage sample & hold linear amplifier; independent pure-play MEMS foundry capabilities on 150mm and 200mm wafers; and HV ASIC design.
Of course, for an electrostatic actuator, the operating voltage increases to generate a higher force.
Teledyne DALSA Semiconductor will feature its latest advancements in MEMS/MOEMS fabrication along with its innovative High Voltage electrostatic actuator ICs at OFC/NFOEC 2013, the world s leading event for advancing optical solutions.
This means that the steam engine with only one piston has about the same force as the electrostatic actuator with 100 beams," said McWhorter, manager of the Silicon Technology Department at Sandia.
HASEL actuators synergize the strengths of soft fluidic and soft electrostatic actuators, and thus combine versatility and performance like no other artificial muscle before.
Valves with electrostatic actuators are often used in micro technology-based systems.
The large section of general papers discusses mechanical brakes for electrostatic actuators, top cap designs for the micro loop heat pipe, the stiffness and resonant frequency of a parylene suspended structure, and improvement of metal thin films by very low energy argon ion irradiation.
Electrostatic actuators have turned up in micromotors demonstrated by Sandia National Laboratories, for example, and in some experimental materials-testing devices.
A force is applied to the sled using electrostatic actuators, though in principle, electomagnetic or thermal actuators could be used.
