Smart patch for flexible monitoring of marine life
Riyadh, May 6: Engineers have developed a thin smart patch called Marine Skin that could make the study of the behaviour of marine animals easier and more informative.
It is a system for electronic tagging of animals that is based on stretchable silicone elastomers that can withstand twisting, shearing and stretching, even when exposed to high pressures in deep waters.
"The integrated flexible electronics can track an animal's movement and diving behaviour and the health of the surrounding marine environment in real time," Joanna Nassar, who was one of the members of the King Abdullah University of Science and Technology team that developed the patch, said in a statement.
"Using simple design tricks and soft materials, we were able to beat the current standard systems in terms of non-invasiveness, weight, operational lifetime and speed of operation," Nassar added.
In the current prototype, the location data is supplemented by recordings of water temperature and salinity. Additional sensing capabilities could be added in future.
"We are consistently advancing the field of flexible and stretchable electronics by making electronic systems in which every component is physically flexible," another team member Muhammad Mustafa Hussain, said.
The data is currently retrieved via wireless connection when the tag is removed. In future, the researchers hope to develop remote data retrieval procedures by overcoming the problems of transmitting signals through water.

Assam to lift all cases against Koch Rajbongshis in Foreigners' Tribunals: CM Himanta Biswa Sarma
Guwahati, Apr 4 (PTI): The Assam cabinet has decided to lift all cases pending against people from the Koch Rajbongshi community in the Foreigners' Tribunals, Chief Minister Himanta Biswa Sarma said on Friday.
They will also no longer carry the tag of 'D' or doubtful voters, he said.
''There are 28,000 cases pending in different Foreigners' Tribunals in the state against people of the community. The cabinet has taken a historic decision of lifting the cases with immediate effect,'' Sarma said at a press conference here after the cabinet meeting.
The government believes that the Koch Rajbongshis are an indigenous community of the state and they are an inextricable part of ''our social and cultural fabric'', he asserted.
The people of this community are poor and have suffered a lot over the years, he said.
''They will no longer carry the tag of foreigners or ‘D’ voters,'' the CM said.
Foreigners Tribunals are quasi-judicial bodies, particularly in Assam, established to determine if a person residing in India is a "foreigner" as defined by the Foreigners Act of 1946, based on the Foreigners (Tribunals) Order of 1964.
These tribunals are designed to address matters related to citizenship and the presence of “foreigners” in India, specifically focusing on cases where someone is suspected of being an illegal immigrant.
There are 100 Foreigners’ Tribunals across Assam.
The Koch Rajbongshis have a sizeable presence in Assam, West Bengal, Meghalaya, and parts of Bangladesh, Nepal, and Bhutan, and they demand Scheduled Tribe status.
