Adjusting an opening of a card edge connector using a set of electroactive polymers

An apparatus to dynamically adjust, in a card edge connector, an opening configured to receive a printed-circuit card, the apparatus comprising:

• the card edge connector having a first position and a second position;
• a set of contacts configured to connect with a set of edges of the printed-circuit card in the second position at both a first contact location and a second contact location, wherein a first distance between the first and the second contact locations in the first position exceeds a second distance between the first and the second contact locations in the second position;
• and
• a set of electroactive polymers configured to change thickness in response to voltages applied to electrodes positioned adjacent to opposing faces of the set of electroactive polymers, the change of thickness adjusting the set of contacts between the first position and the second position, the set of electroactive polymers including an electroactive polymer configured to control a single contact of the set of contacts.
