LG Innotek develops super-slim heartbeat sensor

LG Innotek, a mobile device component affiliate of LG Group, said Tuesday it has developed a super-slim heartbeat sensor module.

The company, which is the world’s leading manufacturer of mobile camera modules, said it will continue to develop advanced sensors to accelerate its growth in the Internet of Things (IoT) market.

“Sensors, which enable collection and analysis of data, are essential in the IoT era,” LG Innotek Senior Vice President Kim Chang-hwan said in a statement. “We will continue to push into the IoT market by developing advanced sensors and connecting them to diverse devices from electronics, wearables and smartphones to automobiles.”

Heartbeat sensors in wearable devices and smartphones are widely used to measure body status information such as heart rate, stress index and oxygen saturation rate. The company said the new heartbeat sensor module is thinner, consumes less energy and has improved accuracy.

“The key in wearable device technologies is to downsize devices while minimizing electricity consumption,” the company said. “Because users should wear the devices to use them, wearable devices cannot be popular no matter how excellent they are functionally if they are cumbersome and consume too much energy.”

LG Innotek has developed key sensor technologies such as an automobile torque angle sensor and a photo sensor for network cameras. Based on its R&D capabilities, it has reached out with a diverse sensor product portfolio, seeking new revenue sources.

LG Innotek said its heartbeat sensor combines a photo diode, light-emitting diodes and a semiconductor chip in a single module only 1 millimeter thick. The company said it has used printed circuit board (PCB) embedded technology to reduce the thickness.

“When applied to wearable devices and smartphones, this module will allow for slimmer and freer designs,” it said.

The company said its living body signal reception capability has been improved by 30 percent compared to existing modules, and thus can operate with about 20 percent less energy consumption.

It also said the module has higher measurement accuracy. It said the module can measure pulse within an error range of 2 beats per minute, which is comparable to that of medical devices.
