Thin Film Flexible and Stretchable Pressure Sensing Mat

The pressure mat is a thin film, flexible, and stretchable mat. The measured pressure distribution data can be acquired via USB, Bluetooth, or wi-fi connection, and displayed on a screen as a pressure heat map that indicates the level of pressure represented by multiple colours.

• Pressure range: 1-1,000PSI, adjustable

• Mat size and shape: customizable

• Sensor density: 0.5-10 sensor points per square centimeter

• Sensor response time: <1us

• Thickness: <0.3mm

• Weight: <1kg

• Communication: USB, Bluetooth, wi-fi connection

• Working voltage: DC 5V

• Power consumption: <3w

Potential Applications

The pressure mat has the capability to sense pressures at multiple points on a flat or curved surface that can find various applications in the fields of fitness, health care, elderly care, robotics, sports, gaming, virtual reality, augmented reality, and medical etc. Some application examples are:

• Smart mat
  • For Yoga instructors and practitioner to monitor palms and feet pressure balance and excessive pressure in order to exercise properly and prevent injury.
  • For weight lifting instructors and lifter to monitor feet pressure balance and excessive pressure. So to train appropriately as well as prevent bodily injury.
  • For infant care: Put on infant beds to monitor the presence of infants and prevent them from falling out of beds.
  • For elderly care: Put on the floor to detect fall and trigger alarm.

• Smart chair: Covered with pressure mat on a seat to monitor and prevent improper sitting posture.

• Smart bed: Covered with a pressure mat on a bed to monitor sleeping behaviour and prevent bed sore.

• Smart insole: Pressure mat inside a shoe to monitor foot pressure distribution and prevent diabetic patients from ulceration and complication.

• Smart haptic glove:
  • Embedded with pressure mat for haptic sensing, to help the physically challenged or elderly to grasp goods.
  • Embedded with pressure mat and put on robotic gripper to facilitate grasping and assembly tasks.
  • Embedded with a pressure mat to help the doctor get haptic feedback during surgical operation.

• Smart skin: Deploy pressure mat on the outer surface of service and industrial robots for collision detection and injury prevention.

• Smart portable and foldable keyboard and mouse: Use foldable pressure mat to achieve better performance than traditional keyboard and mouse, for gaming and other applications.

• Smart portable and foldable musical instrument: The foldable pressure mat can use as an interactive digital musical instrument for playing music, teaching, recording, and composition.
