A liposome formulation for stably incorporating high content of hydrophobic substance is disclosed. For example, shaped forms within the apparatus may be configured to yield a stress gradient on application of the force, and the stress gradient induces the flexoelectric signal. This light emitting device is characterized in that the organic light emitting body comprises at least a blue light emitting layer and a red light emitting layer, the complementary color layer absorbs a part of the light emitted from the organic light emitting body and emits green light, and the device emits white light from the transparent substrate side. The first layer of photo imageable ink is removed, and a second layer of photo imageable ink is applied over the traces and channels between the traces. When soiled, the inner diaper is pulled away by releasing the waist-securing tabs and the adhesive edge flap attachment.
