On-chip silicon photodetector is an integrated optical sensor fabricated on a silicon chip that detects subtle changes in tissue oxygenation. However, the existing studies didn’t consider the blooming effect, affecting the detection of oxygen saturation and heart rate variability and causing false readings in cardiac monitoring. Therefore, Architecture (Ma-Sh architecture) and FIHcLSH-DeepBiLSTM-enabled blooming effect-aware on-chip silicon photodetector for cardiac arrest prediction. Initially, regarding the 760nm LED source, the silicon chip is fabricated by employing NIL. Here, wavelength tuning is done by GL-FO. In real-time, the LED light is passed through the blood vessel . The blooming effect is detected by using WSB-FLS. If the blooming effect is present, then it is detected based on Ma-Sh architecture. Afterward, the light source strikes the photodetector, where the light energy is converted into electrical energy. Then, the cross-talk is identified by employing FFT. Based on CDTW, the cross-talk is mitigated. Thereafter, NIR absorption is increased by PAGC. Subsequently, the depth of the signal in the tissue is estimated. Then, AC components are obtained from the estimated depth. From the AC components, a PPG signal is obtained, which is employed for cardiac arrest prediction. In the cardiac arrest prediction system, pre-processing, peak detection, feature extraction, and cardiac arrest prediction by FIHcLSH-DeepBiLSTM are performed. The results proved that the proposed model achieved a high accuracy of 98.6%.
