The designers at a Wrexham-based firm and in Cardiff University's School of Engineering hope it could cut brain injuries in high impact sports.
Meanwhile, scientists said they have also made a head injury breakthrough.
Experts said they have created an agent to reduce the risk of brain inflammation and infections after a head injury.
The body's natural response to injury is to see damaged tissue as "foreign" and potentially worsen the injury, yet researchers said the agent blocks this response, reducing inflammation and helping recovery.
Cardiff University said the treatment specifically targets injured tissue.
The research was published in the journal Proceedings of the National Academy of Sciences after being tested on mice.
The university will now seek to translate the findings to humans, and said it could be "life-changing" for patients.
It is estimated more than a million people in the UK are admitted to hospital as a result of a head injury every year.

Terence Brannigan, chair of the Maze/Long Kesh development Corporation, was speaking after roads around the former prison site were congested on the first day of the event.
Mr Brannigan said rural roads were "not designed for that kind of traffic"
But he said work was under way to put the new infrastructure in place.
"In 12 months time it won't be the same," he said. "But let's not pretend that in 12 months time we are going to have two roads linking up to the motorway network.
"The work is going on now, as we speak,  in respect of putting two links into the motorway, one from the east and one from the west.
"We are doing environmental studies now in order to get clearance. We will then have to go to planning and from that we will then be able to build the two roads."
Up to 80,000 people are expected to attend the three-day event, which has moved from its previous home at the King's Hall in Belfast.
On Wednesday, First Minister Peter Robinson said he hoped any problems with access would be overcome.
Mr Brannigan said getting the infrastructure sorted had been a priority for the corporation, but acknowledged there was a  "rigorous process" to complete.
"If people have to sit in queues for a long period of time, it can spoil what is a magnificent show, a fantastic event and the showcase for Northern Ireland," he said.
"The money has been ring-fenced so we can't complain that we haven't got the money, we can't complain that we are not getting the support.
"But there is a due process we have to go through.  It is frustrating, nonetheless it is a process we must go through."
Visitors to this year's show have been urged to use public transport.
The Balmoral Show website contains details of how to get to the show by car or by public transport.
