The world's smallest linear motor, at 1.5x1.5x6mm; latest piezoelectric Squiggle motor is half the size of other micro-motors yet offers ten times the precision and push force
The latest Squiggle motor from New Scale Technologies is the smallest linear motor on the market, the company says.
At 1.5x1.5mm, the new SQL-1.5 piezoelectric motor is half the size of competing micro-motors.
It also offers a 20gram push force and sub-micron position resolution, performing ten times better than its closest competitor on both counts.
"The SQL-1.5 opens a whole new range of performance for miniature electronic systems such as phone cameras and medical devices," said New Scale president David Henderson.
"Designers of leading edge mobile devices finally have a precise, reliable linear motor that fits within their size and power budgets".
"They can add motion - and hence new capabilities - where they were unable to do so before." The SQL-1.5 is of interest to medical device manufacturers for a new class of implantable drug pumps and micro-valves.
The motor itself is tiny, but its high precision is what enables the most dramatic reduction in overall device size.
It provides more precise valve control, which permits more concentrated medications and therefore smaller fluid reservoirs.
The patented ceramic motor design generates no magnetic fields and can be made of non-ferrous materials, making it MRI-safe and image compatible.
