LG Innotek Unveils Flexible Textile Pressure Sensors

LG Innotek today announced a development of new concept textile flexible pressure sensors. This sensor senses pressure from the entire surface of the sensor, and it is even bendable.

Pressure sensors can measure the level of the external force. Being installed in medical appliances and automobiles to gauge and analyse the pressure, it is used for customised individual service.

Former commercialised sensors are coin shape and made of PCB substrates or PET films, making them difficult to bend or deform. And it is hard to measure the pressure uniformly from the large area because of its point sensing way. Even it gives a feeling of irritation when the sensor touches your body.

LG Innotek’s sensors have highly elastic polyurethane material to fit your body comfortably. And its measurement of face pressure distribution by sensing capacitance change caused by pressure. The company has filed thirteen patents regarding the related technologies in South Korea and secured the product quality for mass production in this year.

The company’s development of the textile flexible pressure sensors is making them suitable for products such as gloves and chairs that come in direct contact with the human body.

This new pressure sensor makes it possible to implement new features by utilising the pressure information in various areas such as health care and automotive.

In Health-care areas, the sensor helps to improve the accuracy of Telemedicine. When the patients wear the device or walk on the carpet, the sensor can detect body balance and acting patterns. The information from the device will automatically be sent to the medical centre


If you apply this sensor to your sports gear, you can be served more detailed and improved training service for yourself. For example, the sensor detects the pressure of your hands on the golf club as well as the position of your hands. Then, it sends the information to your smartphone to help you find the perfect grip.

You can attach these sensors to automotive for safety and convenience. The sensor understands your posture, body type and weight to automatically correct height of car-seat or pressure of airbag.

If you apply the sensor to a chair, it measures the pressure on the seat and sends the data to you. You can use this information to correct your posture or analyse your study patterns.

The company developed unique polyurethane material that is sensitive to the pressure and has high elasticity and inserted the material between the electronic fibres. When an external force is applied to the sensor, electric poles inside the fibre detect the deformation to determine the pressure.

This product is very durable in various environments. It regularly works over 240 hours from 40 degrees below zero to 80 above zero. A sensor remains functional even after the average 70-kg man sits on the sensor 100,000 times.

Changhwan Kim, Head of the LG Innotek’s R&D Center said, “We tried to break away from the previous method and attempt new ways to develop innovative products.” He also said, “We will continue to develop materials and components in various fields to provide new experiences to our customers.”
