Electromagnetic interactions with biological systems promise new possibilities in medical applications and synthetic biology. Creating a controlled action in biological systems requires an efficient transduction of the electromagnetic energy to thermal or mechanical biosignals. In this paper, we present the design and optimization for a nano-scale magnetic torque transducer based on a tunable nanomechanical resonator. Operating in the resonance regime allows the presented system to efficiently absorb a large amount of energy from the source. In addition, systems tuned on well separated resonance frequencies may operate simultaneously without any interference. We describe the theoretical model of the system and show the possibility of achieving the resonance in biological settings for a system with reasonable dimensions.
电磁与生物系统的相互作用为医学应用和合成生物学带来了新的可能性。在生物系统中产生可控作用需要将电磁能量有效地转换为热或机械生物信号。在本文中,我们展示了基于可调谐纳米机械谐振器的纳米级磁扭矩传感器的设计与优化。在共振状态下运行可使所展示的系统有效地从源吸收大量能量。此外,调谐到间隔良好的共振频率的系统可以同时运行而不会产生任何干扰。我们描述了该系统的理论模型,并展示了对于具有合理尺寸的系统在生物环境中实现共振的可能性。
