Abstract
A wire-based microelectromechanical systems (MEMS) apparatus is provided. In examples discussed herein, the wire-based MEMS apparatus includes a MEMS control bus and at least one passive MEMS switch circuit. The passive MEMS switch circuit is configured to close a MEMS switch(es) by generating a constant voltage(s) that exceeds a defined threshold voltage (e.g., 30-50 V). In a non-limiting example, the passive MEMS switch circuit can generate the constant voltage(s) based on a radio frequency (RF) voltage(s), which may be harvested from an RF signal(s) received via the MEMS control bus. In this regard, it may be possible to eliminate active components and/or circuits from the passive MEMS switch circuit, thus helping to reduce leakage and power consumption. As a result, it may be possible to provide the passive MEMS switch circuit in a low power apparatus for supporting such applications as the Internet-of-Things (IoT).
