A small Israeli company has developed a sensor technology it says is 10,000 times more sensitive than what’s available today in products like heart monitors and MRIs.

The tiny company is poised to capture a chunk of a $50 billion market, analysts say.

The technology will lead to one of the first remote sensing devices that can provide readings from several feet away without physical contact, according to executives at Nexense. That could mean no more sweaty heart monitor straps and no more grabbing handles while running on a treadmill — the device could get a signal through a wristband or a patient’s feet. Devices that could use the Nexense technology include heart monitors, satellites, cell phones and automobiles. It could even help people stop snoring.

One of the company’s first products will be a flat plastic vital-sign detector about the size of a sheet of paper, that slips underneath a mattress. If someone has, say, a stroke, the device could awaken the victim’s bedmate immediately. Another version of the device will help prevent sudden infant death syndrome, and future models could report episodes associated with epilepsy or asthma.
