AI RESEARCH ANALYSIS
An insect-scale artificial visual-olfactory bionic compound eye
This research details the development of a miniature apposition compound eye, integrating 1027 ommatidia within a 1.5 mm² surface area. It combines visual and olfactory sensing capabilities, mimicking an insect's multimodal perception. The system enables wide-angle, close-range obstacle avoidance and real-time monitoring of both visual and olfactory information, with potential applications in unmanned platforms and bionic robotics.
Executive Impact
The core innovation lies in the integration of 1027 ommatidia on a 1.5x1.5 mm² flexible photodetector, combined with an inkjet-printed colorimetric olfactory sensor array, to achieve insect-scale visual-olfactory fusion with high sensitivity and rapid response.

Bionic Design & Precision Fabrication
The system mimics the Drosophila compound eye, integrating a microlens array (MLA) with a flexible organic photodetector (OPD) array via femtosecond laser two-photon polymerization (FL-TPP). This ensures precise one-to-one alignment and effective optical isolation, overcoming traditional lens-pixel mismatch issues. The flexible polydimethylsiloxane (PDMS) film acts as both an encapsulation layer and an optical medium.

Multimodal Sensing & Rapid Response
The P3HT/PCBM/PbS QDs photodetector array offers 0.1 ms photoelectric response and broad-spectrum detection (UV-Vis-NIR), achieving a 1 kHz flicker fusion frequency. The inkjet-printed colorimetric olfactory sensor array provides rapid gas response and concentration visualization for various hazardous chemicals, enabling high sensitivity to moving objects and environmental gases.
| Feature | Bio-CE (This Work) | Typical CMOS-based System |
|---|---|---|
| Flicker Fusion Frequency | 1 kHz (Superior) | < 1 kHz |
| Photoelectric Response Time | 0.1 ms (Rapid) | > 1 ms |
| Spatial Resolution | Lower (Prioritizes motion) | Higher (Static detail) |
| Multimodal Sensing | Visual + Olfactory | Visual only |
| Energy Efficiency | High (Sparse data) | Moderate (Full image capture) |
Real-time Obstacle Avoidance
The bio-CE was integrated into an unmanned omnidirectional vehicle (UOV) system. It demonstrated high-sensitivity motion detection and rapid obstacle avoidance in both passive (retreat from approaching targets) and active (steering during autonomous cruising) modes. The system achieved accurate recognition of target contours and high sensitivity to changes in position and motion state, even under fogging conditions due to its bionic setae array.
Panoramic Perception & Bionic Robotics
This insect-scale bionic compound eye offers a unique solution for multimodal perception in complex environments. Its capabilities for wide field-of-view imaging, rapid motion detection, and chemical sensing pave the way for advancements in unmanned platform navigation, environmental monitoring, and bionic robot intelligence, enabling adaptive behavioral responses akin to biological organisms.
