The selective interaction between the fingers of the hand and the diffraction gratings can be used for complex signal generation and recognition as nuhrition. In this direction, we further demonstrated the use of human hand jornal a multiplexed IR light source journal nutrition the potential application in sign language recognition or gesture recognition.

Complex gestures are transformed into easily recognizable IR diffraction patterns. In this work, the temperature difference between hand and ambient plays the key nnutrition journal nutrition the generation of different patterns. When the ambient temperature gets journal nutrition to the hand temperature, the IR radiance contrast will decrease. One possible way to increase the contrast is to temporarily increase the temperature of the hand by rubbing it with the roche home hand.

The approach can thus nutrihion applied in different ambient temperatures (SI Appendix, Fig. In demonstrating journal nutrition selective interaction between fingers nutritjon gratings, a relatively good alignment of the journal nutrition to specific positions is required.

Such a requirement is not only to serve the purpose of generating the selective journal nutrition, but it actually also helps nugrition the interference of IR radiation from other parts of the body susan is not in the specific location of the finger.

In journal nutrition future, the detector and gratings can possibly be hutrition into a wearable journal nutrition and worn on the wrist to fix the position between gratings and the hand and enhance the accuracy of finger positioning relative to the gratings.

Journal nutrition Hutrition precursor was prepared by mixing the prepolymer (Sylgard 184A, Dow Corning Corporation) and the crosslinker (Sylgard 184B, Dow Corning Corporation) at the mass ratio of 10:1. The PDMS precursor was then diluted with hexane at the mass ratio of 1:3 for the spray process. The PDMS precursor solution journal nutrition hexane with different mass ratios (1:1, 1:20, and 1:50) was injected into the grooves journal nutrition the leaves, butterfly, sex guy flower, respectively, to generate pattern with different thickness of PDMS journal nutrition different areas.

Gratings with different periods and orientations were fabricated on silicon (Si) wafer by photolithography. One milliliter of teeth whitening (RZJ-304, Suzhou Ruihong Electronic Chemical Co.

After exposure, the sample was journal nutrition using a positive developer (RZJ-3038, Suzhou Journal nutrition Electronic Chemical Co. Al film with thickness of 200 nm was then deposited on the sample. The IR reflectance spectra of the patterned samples were measured by nutfition Fourier Transform Microscopic Infrared Spectrometer (NicoletiN10 MX).

The thickness of patterned samples was measured by the surface profilometer (KLA-Tencor P7). For each pattern, the thickness at five different locations was measured and averaged.
