Sensor Sunday: Self-Cleaning Sensors, Environmental Sensors and Sensing Art

Sensors are more and more prevalent, and with this weeks news, we see how they’re presence is growing, from self-cleaning sensors to sensors in art to environmental sensors.

Self-Cleaning Electrodes Will Make Sensing Better

Electrode-based sensors are becoming more and more prevalent, but keeping them clean for optimal sensing is a challenge. A team of scientists from Italy have designed an electrochemical sensor that self-cleans by being exposed to ultraviolet light. The sensor has a photoactive top layer of titania that cleans itself with ultraviolet light. The team hopes that the titania cover will be useful on electrode surfaces.

Sending Robots Into Mines with Sensor Fusion Technology

Researchers at the University of Chile and the Advanced Mining Technology Center are exploring ways to use the Husky unmanned ground vehicle to collect important data from mines, including motion and noise characteristics, which map the open pit an underground mines. The sensors have been integrated using the Robot Operating System, allowing quicker analyzation of the information. The team hope to improve resource extraction and worker safety.

Monitoring the Oceans through Cyber Means

From mines to the ocean. Scripps and the Ocean Observatories Initiative is collecting and disseminating data from hundreds of sources. OOI has a vast system of ocean moorings, sea gliders, seafloor cables and various sensors to monitor the conditions of the ocean. Now, the team have shown that their cyberinfrastructure can instantly relay and process data in a way never before seen, allowing ocean scientists and researchers to get data securely in one click.

Elements of Refusal by Brendan Walls (photo credit: Mona Foma)

Brendan Walls has been working on his Elements of Refusal piece for years, and this weekend he was able to put it on display at the Mona Foma Festival in Hobert, Tasmania. The piece uses motion, moisture and temperature sensors to sense changes in the environment and trigger the mechanics of the installation to come to life and make noise. There was plenty more music and arts pieces at the festival, but Brendan’s provides an interesting look at the play between cause and effect.
