Vibrational communication is a suitable method for exchanging important personal information between information technology devices. Since the vibration propagates only through the vibration medium, the information signal is spatially limited, and it prevents any eavesdropping. However, it has proven slow and unreliable. Therefore, we proposed a vibrational communication method using the ultrasonic band. The characteristics of the vibration propagation were measured using piezoelectric elements as the transmitter and receiver and plastic toy blocks as a vibration medium. We performed a successful demonstration of the vibrational communication using a time period per bit of 2 ms, achieving a bit rate of 500 bps. To eliminate unpleasant noise and vibration sensations, a micro-electro-mechanical system (MEMS) resonant device using a higher frequency band was designed and used to simulate its frequency characteristics. Subsequently, the MEMS device was fabricated and a vibrational communication using the MEMS device successfully achieved a bit rate of 4 kbps.

-In this paper we compare the cascade mechanisms of signal amplification in biological and electrical engineering systems, and show that they share the capacity to considerably amplify signals, and respond to signal changes both quickly and completely, which effectively preserves the form of the input signal. For biological systems, these characteristics are crucial for efficient and reliable cellular signalling. We show that this highly-efficient biological mechanism of signal amplification that has naturally evolved is mathematically fully equivalent with some man-developed amplifiers, which indicates parallels between biological evolution and successful technology development.

Transimpedance amplifiers using three cascade variable inverter gain stages

Abstract: A study of a transimpedance amplifier (TIA) using three cascade variable inverter gain stages is presented. It is shown that wide dynamical range ( − 38 dbm) and high bandwidth (500 Mhz) TIA can be achieved. This configuration is good for the optical transmission of OC-3.
