Yap, who lives in Silicon Valley and works at Menlo Ventures, is pulling things together.
"I really think that the basic technologies are there," he said. "But it only takes one to weave them together to facilitate their installation."
From a product perspective, one of the big challenges is making gadgets useful, intuitive, and affordable without the sensors being too invasive and expensive.
"The industry is still a group of enthusiasts trying to gather the elements of a solution to monitor their parents," said Michael Skaff, a veteran of the technology industry who is now the chief operating officer of the Jewish Senior Living Group in San Francisco.
Skaff said that a number of sensor types might prove useful, especially when all data is aggregated. There are sensors for refrigerators that can track if they have been opened recently, moisture sensors to monitor water leaks, smart locks and connected lights that can turn on. the night. There are also sensors that can be placed on doors and windows, which provide an update when a person comes in or out of the house.
Traditional medical devices are also increasingly related to smartphone applications, and data can be shared with caregivers and children, provided that users consent.
"It's still a little risky, but we're getting there," said Scaff.
