The present embodiments relate to a shape memory alloy (SMA) actuator with a reduced number of materials for manufacturing the actuator. In some instances, elements of the SMA actuator can comprise a dielectric material disposed on the actuator via an injection molding process. In other instances, the SMA actuator can dispose SMA wires above a base of the SMA actuator without the use of any dielectric material. In a first example, an SMA actuator can include a carriage and a base. The base can include a fixed end fixed to the carriage, a free end, a beam connecting the fixed end and the free end, and at least one SMA wire. The SMA actuator can also include an insulator comprising a dielectric material electrically isolating a set of electrical contacts at the fixed end.

A semiconductor device includes a semiconductor element, a laminated substrate including an insulating board and a circuit board disposed on the insulating board, the semiconductor element being mounted on the circuit board, a surrounding case having an opening, and being disposed on the outer peripheral portion of the insulating board to surround the circuit board, a relay substrate having a through hole and being disposed on the surrounding case to cover the opening, and an external connection terminal including a first end portion bonded to the circuit board, a second end portion, opposite to the first end portion, inserted into the through hole of the relay substrate from the rear surface of the relay substrate so as to be in contact with the front surface of the relay substrate, and an elastically deformable elastic portion between the first end portion and the second end portion.

Disclosed aspects include an apparatus having a card edge connector which has first and second positions. The apparatus may include a set of contacts to connect with a set of card edges in the second position. To adjust the set of contacts between the first position and the second position, the apparatus may include a set of electroactive polymers. Disclosed aspects include card edge connector management. It may be detected that a card edge connector is in a first position. A request for the card edge connector to be in a second position can be received. It is determined to adjust the card edge connector. The card edge connector is adjusted using a set of electroactive polymers. In embodiments, such adjustment can include introducing a voltage which causes the set of electroactive polymers to adjust a set of contacts between the first and second positions.
