Nanomaterial Flexible Pressure Sensor

Featuring a 30 mm diameter active zone and overall footprint of 60 mm × 5.8 mm, this pressure sensor uses highly sensitive flexible nanomaterials to detect forces from 0 to 30 kg. Measuring less than 0.60 mm thick and weighing only 1 g, it maintains mechanical flexibility without sacrificing repeatability. It delivers stable performance across temperatures ranging from -20°C to +60°C and is rated for more than 1 million operational cycles. Key electrical characteristics include a typical test voltage of DC 3.3 V, initial resistance exceeding 10 MΩ, detection threshold below 200 g, and response/recovery times under 1 ms and 15 ms respectively. It is inherently waterproof, emits no EMI, and exhibits no ESD sensitivity — making it suitable for direct integration into diverse environmental conditions. Signal extraction is achieved through resistance modulation: applied pressure alters internal conductive pathways, producing a measurable resistance drop. This analogue output can be read using basic voltage divider circuits and standard microcontroller ADCs — no special ICs or libraries required. Target applications include smart home automation (e.g., pressure-activated switches in cabinets or beds), automotive electronics (e.g., seatbelt tension sensing or dashboard button feedback), and new energy infrastructure (e.g., compression monitoring in hydrogen storage vessels or solar tracker mounting joints).
