Microsystems with embedded sensors and actuators, or micro-electro-mechanical systems (MEMS), have developed increased functionalities that could allow the treatment and monitoring of lesions inside the body in a minimally invasive manner. However, significant barriers to their use in biological environment include their ineffective interaction with three dimensional (3D) tissues caused by their planar forms, fragility associated with their design complexity, and biocompatibility issues, leading to severely hindered performance or malfunctions of the devices. MEMS-based implants are still too large in many cases including vascular applications. Moreover, wireless operation is essential for implantable microsystems. Addressing these challenges require breakthrough approaches.

具有嵌入式传感器和致动器的微系统或微机电系统（MEMS）已经开发了更多的功能，可以允许以微创方式治疗和监测体内的病变。然而，它们在生物环境中使用的重大障碍包括由其平面形式引起的与三维（3D）组织的无效相互作用、与其设计复杂性相关的脆弱性以及生物相容性问题，导致器械的性能严重受阻或故障。基于MEMS的植入物在包括血管应用在内的许多情况下仍然太大。此外，无线操作对于植入式微系统是必不可少的。应对这些挑战需要突破性的方法。
