We present a reprogrammable Microelectromechanical systems (MEMS) logic device that can perform the fundamental logic gate AND, a universal logic gate NAND, and a tristate logic gate using mixed-frequency excitation. The concept is based on exciting combination resonances due to the mixing of two or more input signals. The device vibrates at two steady states; a high state when the combination resonance is activated and a low state when no resonance is activated. These vibration states are assigned to logical value 1 or 0 to realize these logic gates. Using AC signals to drive the resonator and to execute the logic inputs unifies the input and output wave forms of the logic device, thereby opening the possibility for cascading among logic devices. Moreover, the ability to perform these logic operations at any input frequency using frequency mixing techniques allows for overcoming the limitation of having a fixed operating frequency. These characteristics of such logic devices lay down the basis to achieve complex computing operations.

“…Switch based MEMS/NEMS logic devices have been demonstrated capable of performing multiple logic operations using a single structure [2,3]. These devices however have limitations in practical application due to wearing of the contacting surfaces over time, in addition to other stiction and friction issues [4].…”

“…This mode has the advantages of zero leakage current and the ability to easily cascade multiple elements to execute complex logic operations. However, their high contact resistance, low speed, and stiction issues limit their potential in demonstrating practical applications [7,8]. Therefore, a new research direction has emerged focusing on the noncontact mode by employing the dynamic vibration of MEMS and NEMS resonators.…”

Performing Boolean operations using conventional CMOS-based computers requires the wiring of multiple transistors. Hence, the processors of these computers are composed of millions of transistors, which increase the device size and power consumption. Here, we present a single MEMS resonator that can execute in parallel multiple logic gates. The concept is based on simultaneously encoding the binary information at different modes of vibration of a microplate. The proposed novel method allows the device not only to perform as a fully integrated logic gate but also as a parallel logic processor for which the same device can perform multiple logic gates simultaneously. The proposed method decreases the device footprint and reduces the power consumption required to perform multiple Boolean functions.

We present an investigation of the dynamic behavior of an electrostatically actuated clampedclamped microbeam, under the simultaneous excitation of primary and subharmonic resonance. The simultaneous excitation of primary and subharmonic resonances of similar strength is experimentally investigated by using different combinations of AC and DC voltages. It is observed that the response of the resonator is governed by a mixed effect of both excitations. Subharmonic dominated response shows sharp amplitude transitions and smaller monostable regime, while primary dominated response shows gradual amplitude transition and larger monostable regime. Two potential applications are experimentally demonstrated. The first is a resonator based MEMS AND logic gate based on AC only subharmonic excitation. The second is a charge sensor based on the transition from subharmonic dominated response to primary dominated response, which is potentially capable of detecting a small amount of electric charges.
