NRI develops tech to prolong pacemaker life

The technology "Silicon on Insulator" (SOI) has been developed by Dr Amar Pal Singh who has set up a company.

A California-based Indian scientist claimed to have developed a new technology that can revolutionise the functioning of electronic devices such as pacemaker (used in people with defective heart) by making them smaller and last for almost 30 years.

The technology "Silicon on Insulator" (SOI) has been developed by Dr Amar Pal Singh who has set up a company.

"I have sold the technology to a US-based company, engaged in making radiation-resistant space equipment," Dr Rana said from California over the phone.

"The technology is based on use of very low voltage, which in turn reduces power consumption in devices," Rana said.

The technology was very important for devices such as the pacemaker that consumed power and got switched on everytime the heart did not beat, he said.

By reducing power consumption, the battery would last longer and would also reduce the size of pacemaker. Such a pacemaker would last up to 30 years, he claimed.

Currently, pacemakers last for about 12 years, thus, necessitating patients to undergo a surgery again.

The same applies for a cell phone whose battery is responsible for its size, its electronic chip being very small. The size of a cell phone could be reduced by 40 per cent, Rana claimed.

The SOI technology was based on preventing the loss of heat during processing of signals, A P Singh, Rana's brother here who works with him, said.

Rana has got a US patent for the technology.
