Bio-Inspired Polarized Skylight-Based Navigation Sensors: A Review
Animal senses cover a broad range of signal types and signal bandwidths and have inspired various sensors and bioinstrumentation devices for biological and medical applications. Insects, such as desert ants and honeybees, for example, utilize polarized skylight pattern-based information in their navigation activities. They reliably return to their nests and hives from places many kilometers awa...
متن کاملComment on ‘ A depolarizer as a possible precise sunstone for Viking navigation by polarized skylight ’
A main conclusion of this work by Robars et al. is that a piece of Iceland spar (optical calcite) can be used in a simple manner to find the direction to the Sun using polarized light, even when the Sun is obscured by clouds or just below the horizon, which supports the possible role of the renowned sunstones discussed in Viking Sagas. They propose a method of using an opaque spot on the incomi...
متن کاملBio-Inspired Miniature Direction Finding Acoustic Sensor
A narrowband MEMS direction finding sensor has been developed based on the mechanically coupled ears of the Ormia Ochracea fly. The sensor consists of two wings coupled at the middle and attached to a substrate using two legs. The sensor operates at its bending resonance frequency and has cosine directional characteristics similar to that of a pressure gradient microphone. Thus, the directional...
متن کاملOptimization Of Bio-inspired Hair Sensor Arrays
Crickets use a pair of hairy appendages on their abdomen called cerci, each of which contains numerous mechano-receptive filiform hairs (Fig. 1). These sensitive hairs can respond even to the slightest air movements, down to 0.03 mm/s, generated by the approaching predators and initiating an escape mechanism in the crickets [1]. Bio-mimicking the cricket cerci, arrays of artificial hair sensors...
متن کاملBio-Inspired Data Acquisition in Sensor Networks
I. OVERVIEW Field estimation is an important application of wireless sensor networks. This type of application deploys sensor nodes in a specific region to remotely sense space-temporally variable processes. The spatial and temporal frequencies of sampling directly impact the quality of the estimation. Therefore, there is a tradeoff between the frequency and the number of samples transmitted, w...
