All of these systems are relying on an active magnetic regenerator (AMR) concept, where a heat transfer fluid is actively pumped through a bed of magnetocaloric material in order to transfer ...
Technics’ biggest technical addition to these earbuds is technology called the “Magnetic Fluid Driver,” first introduced in the Technics EAH-TZ700—a set of $1,199 wired earphones.
This creates local magnetic markers in the fluid, which are detected in a third step by highly sensitive quantum sensors through the pipe wall after the fluid has flowed through a defined ...
