We describe, in this paper, a new digital input-output power configurable PAD (CPAD) for a wafer-scale-based rapid prototyping platform for electronic systems. This wafer-scale platform includes a reconfigurable wafer-scale circuit that can interconnect any digital components manually deposited on its active alignment-insensitive surface. The whole platform is powered using a massive grid of embedded...
The concept of sending and receiving analog signals through a digital interconnection network is presented in this paper. The proposed “analog bus” addresses limitations of a novel rapid prototyping platform called the WaferBoard™ that was initially designed to support prototyping of all digital circuits with its embedded fully digital interconnection network. This paper explores the simplest and...
This paper introduces the power supply analysis of a large area integrated circuit (LAIC) used in a rapid prototyping platform for electronic systems. User integrated circuits deposited on this active LAIC surface receive power through configurable IOs. Strategies to distribute power all over a LAIC of the size of an entire wafer are described, modeled and their performances evaluated. Different scenarios...
This paper presents the electrical characterization of annular TSV technology for full wafer applications. A possible utilization of this technology is the WaferBoard™, a reconfigurable circuit board for rapid system prototyping. Electrical resistance and capacitance of a single 2-4µm thick annular TSV with a diameter of 110µm and a height of 350µm are measured to be about 10mΩ and 0.27 pF, respectively...
Standard transmission methods such as RF have been considered for untethered robots that need to send messages and information to an external computer. But, as the overall sizes of such robots decrease, the implementation of such transmission systems within the space and power constraints becomes more challenging. For microrobots, the challenge is even greater and furthermore, the overall size of...
Experimental data and proofs of concepts are used to show the feasibility of providing the basic components and functionalities required for the implementation of intelligent untethered 150 × 300µm bacterial microrobots capable of sophisticated collective tasks under computer supervision and coordination. More specifically, we show that it is possible to embed within such microrobots, photovoltaic...
The preliminary design of photovoltaic cells to be embedded in untethered aqueous microrobots, a few hundred micrometers in overall length, is briefly described. A total of 4 cells with an estimated efficiency of 12.5% should provide up to 100 microamperes of photonic current to the electronics embedded in each untethered microrobot from an incident source of green light. The need for power has been...
The initial design of a 500 mumtimes200 mum untethered microrobot for future operations in an aqueous medium is briefly described. Electrical energy requirement is minimized by exploiting the motility of magnetotactic bacteria embedded in special reservoirs and used to propel the microrobot. An embedded control microcircuit powered through photovoltaic cells is developed to control the swimming directions...
