A coherent-light single-pixel camera was used to interrogate a Fabry–Perot polymer film ultrasound sensor, thereby serially encoding a time-varying 2D ultrasonic field onto a single optical channel. By facilitating compressive sensing, this device enabled video rate imaging of ultrasound fields. In experimental demonstrations, this compressed sensing capability was exploited to reduce motion bl...

Since conventional sampling and laboratory soil analysis do not provide a cost effective capability to obtain georeferenced measurements with adequate frequency, different onthe-go sensing techniques have been attempted. One such recently commercialized sensing system combines mapping of soil electrical conductivity and pH. The concept of direct measurement of soil pH has allowed for a substant...

Thermal sensors based on thermopiles are some of the most robust and popular temperature sensing technologies across industries and research disciplines. A chip calorimeter with a 3D thermopile layout with a large sensing area and multichannel capacity has been developed, which is highly desired for many applications requiring large reaction chambers or high throughputs, such as biofilm researc...

SUMMARY Ionic polymer metal composites (IPMC) have been widely investigated as newly-emerging materials for transducer applications due to their good performance, such as low weight, good flexibility and large strain. A bio-inspired design was described and applied to build 3-D papillae dome structure for vectorial tactile sensors. INTRODUCTION The electrical-chemical-mechanical effect in ionic...

Current research and improvements in the field of wireless sensor networks are focused on decreasing the power consumption and miniaturization, improved smartness and better wearability of the sensor, and especially with their capability for environmental sensing. Today, the survival of these kinds of networks is a critical issue especially in order to keep environmental information updated. Th...

We present a compact and easy to handle instrument developed to perform rapid analysis of liquids utilizing an "electronic tongue" system. Briefly, the e-tongue used here is based on impedance measurements of an array of sensing units fabricated with ultrathin films of different materials deposited onto gold interdigitated electrodes. The instrument has the capability of measuring up to eight d...

In this paper we propose an object-centric method of augmenting mobile smart objects using projection onto the surface of the objects. We assume that the objects are both real world objects with an inherent use, and autonomous computational nodes that can communicate with the environment in real time. We investigate how an object’s capability for self description and sensing can be used in coop...

A source-seeking process for a pair of simple, low capability robots using only point measurements is proposed and analyzed. The robots are assumed to bememoryless, to lack the capability of performing complex computations and to have no direct communication abilities. Their only implicit formof communication is by sensing their relative position and the only response of a robot to the point me...

Hearing aids are electronic, battery-operated sensing devices which aim at compensating various kinds of hearing impairments by means of appropriate signal processing. Most of today’s hearing aid systems consist of two appliances working independently of each other. However, collaboration using a wireless communication link would allow to improve the overall beamforming capability of the system...

One application that merits closer examination is the use of SPOT panchromatic imagery (10 meter resolution) to detect and monitor troops massing along an international border, near a demarcation line, or at key transportation nodes deep within a country. If commercial imagery acquired by the SPOT satellites or by comparable remote sensing systems could be used for such a purpose, the analysis ...
