Abstract
According to an embodiment, a self-powered sensor comprises at least one first layer emitting light in a preset wavelength band by receiving power from an outside, or receiving the emitted light reflected by an object, at least one second layer receiving light and generating a current, and a plurality of connectors each grown between two adjacent ones of the at least one first layer and the at least one second layer, the plurality of connectors transferring the generated current to the outside or transferring the power received from the outside to the at least one first layer and the at least one second layer.
Claims11
A self-powered sensor, comprising:
- at least one first layer emitting light in a preset wavelength band by receiving power from an outside, or receiving the emitted light reflected by an object;
- at least one second layer receiving light and generating a current;
- and
- a plurality of connectors each grown between two adjacent ones of the at least one first layer and the at least one second layer, the plurality of connectors transferring the generated current to the outside or transferring the power received from the outside to the at least one first layer and the at least one second layer.
A self-powered sensor, comprising:
- at least one first layer emitting light in a mid-infrared wavelength band by receiving power from an outside, or receiving the emitted light reflected by an object;
- at least one second layer formed on the at least one first layer, emitting light in a near-infrared wavelength band by receiving power from the outside, or receiving the emitted light reflected by the object;
- at least one third layer formed on the at least one second layer and receiving light and generating a current;
- and
- a plurality of connectors each grown between two adjacent ones of the at least one first layer, the at least one second layer, and the at least one third layer, the plurality of connectors transferring the generated current to the outside or transferring the power received from the outside to the at least one first layer, the at least one second layer, and the at least one third layer.
A method for manufacturing a self-powered sensor, the method comprising:
- a first growth step of growing a first layer, a second layer, and a third layer, the first layer emitting light in a mid-infrared wavelength band by receiving power from an outside, or receiving the emitted light reflected by an object, the second layer emitting light in a near-infrared wavelength band by receiving power from the outside, or receiving the emitted light reflected by the object, and the third layer receiving light and generating a current;
- a second growth step of growing a connector on each of the first layer, the second layer, and the third layer;
- and
- a repeating step of repeating the first growing step and the second growing step multiple times.
