How do they propose to do this? A little device mounted near each brake pad? A skim of the paper doesn't appear to show an opinion from them beyond citing this prior study [1]. The conclusion of the cited paper appears to show a progression towards a target:
> This study is our first step to install dust collectors in actual vehicles, in order to reduce the brake wear PM emissions. In this study, we evaluated the collection efficiencies of an inertial separator, an ESP, and a hybrid precipitator, independently. In the next stage, we will design a suction system that considers the structure and space of the brake system; then, the full dust collector system setup will be installed on a vehicle. At the final stage, the actual collection efficiency of the dust collector will be measured under various on-road driving conditions.

- petre 3y agoToo complicated, why not use a magnetic brake instead? The electric motor on hybrids essentially operates like a magnetic brake during regen. Works in 80% of the scenarios and for the rest of 20% we can just use the regular brakes.
