Disclosed is a bone regeneration device which forms an electric field on a scaffold inserted into a bone damage site. The present bone regeneration device comprises: a battery; a first electric conductor to be connected to a first electrode of the battery and inserted into a bone located on one side of the scaffold; and a second electric conductor to be connected to a second electrode of the battery and inserted into a bone located on the other side of the scaffold, wherein the battery forms an electric field on the scaffold by applying voltage to the first electric conductor and the second electric conductor.

Bone regeneration device

Disclosed is a shape memory alloy. The shape memory alloy is composed of Ti, Ni and Si, wherein Si is contained in an amount of 0.1 to 0.3 at. %.

Shape memory alloy comprising Ti, Ni and Si

Disclosed is an electrode. An electrode according to the present invention includes an active material layer; and a current collector which includes a plurality of conductive filaments, wherein at least one from among the plurality of conductive filaments is embedded in the active material layer so that a set length is exposed from the surface thereof.

Electrode, and method for producing battery and electrode

A tube-structured battery to be inserted into a living body is provided. The tube-structured battery includes: a biofuel battery part which generates electric energy by using biofuel in the blood passing through an internal space of the tube structure; a transformer circuit part which adjusts a voltage or current density by using the generated electric energy; and a secondary battery part which is charged with the electric energy by using the adjusted voltage or current density to store the electric energy, wherein the tube-structured battery is inserted into the living body or a blood vessel of the living body.

Tube-structured battery to be inserted into living body

A battery mounted semiconductor device is provided. A battery mounted semiconductor device comprises a semiconductor silicon wafer, an electric power supply formed on a backside of the semiconductor silicon wafer and a circuit pattern formed on a front side of the semiconductor silicon wafer.

Silicon wafer for semiconductor with powersupply system on the backside of wafer

Disclosed is a semiconductor silicon wafer having an electric power supply affixed to the backside of the wafer. By fabricating the electric power supply onto the backside of the wafer that has been left unused, the semiconductor chip can have a self-supplied power, realizing the self-powered semiconductor chip with an increased efficiency. Further, since the electric power supply is installed on the wafer, not the semiconductor chip, the fabrication procedure becomes very simple, and the battery can be mounted on any type of chip.
