Despite their potential, microrobots face several challenges:
1. Power Supply: Providing a reliable power source for microrobots is difficult due to their small size. Researchers are exploring wireless power transfer and energy harvesting from the environment as possible solutions.
2. Navigation and Control: Controlling the movement and actions of microrobots with high precision is challenging. Techniques such as magnetic fields, light, and chemical gradients are being developed to address this issue.
3. Biocompatibility: For medical applications, ensuring that microrobots are biocompatible and do not cause adverse reactions within the body is crucial. This involves using materials that are non-toxic and can be safely degraded or removed.
