Participatory urban sensing relies on sensors carried by citizens, such as those on smart phones, to capture data about infrastructure and service usage. This work performed by a team from Brussels presents a citizen science experiment for mapping noise in a 1 km2 area in the city of Antwerp using NoiseTube, a sensing framework developed for certain mobile phones.

MOS gas sensors review

In this review published in the journal “Sensors” in June 2010 by a team at University College London,  the nature of the gas response and how it is fundamentally linked to surface structure is explored. Synthetic routes to metal oxide semiconductor gas sensors are also discussed and related to their affect on surface structure. An overview of important contributions and recent advances are discussed for the use of metal oxide semiconductor sensors for the detection of a variety of gases—CO, NOx, NH3 and the particularly challenging case of CO2.

High-frequency measurements of nitrogen monoxide (NO), nitrogen dioxide (NO2) and carbon monoxide (CO) were made using a dense network of electrochemical sensors at urban sites in Cambridge from March – June 2011, with the aim to improve understanding of the behaviour of these species on fine spatial and temporal scales.

As its first standalone mHealth solution, Sensaris is releasing pulse oximetry solution compatible with 90 % of the mobile phones and tablets sold today.

As a  result of several years of close cooperation with doctors and users, the software (iOS, Android or J2ME)  is easy to install, configure and use.

We chose oximetry first because there are close to 650 000 surgical procedure are performed every day worldwide and pulse oximetry is now a standard to detect hypoxemia, and perioperative or postoperative complications. Just to equip operating rooms in poor or emerging countries, WHO estimates that there is an immediate need for 100 000 units.

In OECD markets, besides being widely used by anethesiologists in hospitals, it is increasingly purchased by subacute care centers, EMS or for home monitoring .(COPD, sleep apnea).
