Printed pressure sensitive sensors

Piezosensitive materials

Piezoelectric sensors react to pressure. At RISE Printed Electronics we work with all-printed piezo sensors:

• Conversion of mechanical stress to electrical signal
• Dynamic measurements – no detection of static strain
• Different piezo modes possible

Piezosensors give distinct advantages

• Custom made design and materials choice
• Freedom in choice of size, geometry and layout
• Opportunities for integration into product – no assembly required
• Low cost in large volumes
• Large signal output

• Fully printed sensors
• Screen printing – robust and cheap manufacturing
• Low temperature processing
• Non-toxic materials
• Freedom in choice of carrier material
• Opportunities for integration into product – no assembly required
• Based on PVDF-type polymers
• Sensor performance comparable to other technologies (e.g. PZT)
• Voltage response up to 10’s of Volts
• Frequency response Hz to MHz
