Why am I getting electric shock from 12V DC Adapter
The most probable reason for the electrical shock is the value of the (Y-rated) capacitor that sits between the mains side of the adapter and the low voltage output. This capacitor is needed to provide a return path for the high-frequency (about 100 - 200 kHz, not that high) with which the isolation transformer is fed.

What happens if a Y capacitor fails in a short circuit?
It would potentially lead into hazardous situations if an Y capacitor would fail into a short circuit. However, Y capacitors are special safety capacitors that are specifically designed to fail into an open circuit to prevent hazardous situations. And Y capacitors are also used on ungrounded equipment.
Can dynamic capacitance regulation improve electric vehicle energy recovery systems?
The novelty of this research lies in the first application of dynamic capacitance regulation technology to the energy recovery system of electric vehicle piezoelectric shock absorbers, providing a new theoretical foundation and technical reference for optimizing electric vehicle energy recovery systems.
Is a 12V capacitor dangerous?
(You can still get shocked from 12V, but given special circumstances.) The next factor is the capacitor's charge capacity. If the stored charge is at a sufficient voltage to create a current, then any capacitor can be dangerous. The charge capacity will dictate how long the current is capable of flowing.
