Impaired-driver sensor could pave the way for safer vehicles

The bipartisan infrastructure bill recently signed into law by President Joe Biden includes a requirement for automakers to install driver monitoring systems that detect intoxicated or impaired drivers. Current systems rely on cameras, which have limitations. Now, researchers reporting in ACS Applied Electronic Materials have made heat-resistant, pressure-detecting sensors that, when attached to seats, can tell whether a driver is drowsy or has a sudden illness, signaling a future smart car to take action.
