In 2019, GTM  developed the first wireless system installed in a magnesium impact headform. The system is used to transmit and receive real-time data when performing a shock test.

This system, named model 6700-WIR6X, is used to record data of linear and rotational acceleration in the ECE 22/06 and FIM tangential tests.

It has a a 7 channel – 24 bits – 35.5 Khz A/D converter, batteries, a radio module as well a DTS6DXPRO A accelerometer. All these components are installed in a cylinder frame with a total mass of only 430 grams.
