This 3D-printed flexible tactile sensor features high sensitivity (867 kPa⁻¹), fast response (10 ms), and low power use (0.1 V). It is made in minutes (<10 minutes), with a unit cost below 100 NTD. The sensor is scalable, customizable, and fits curved surfaces. Applied in badminton grips and insoles, it enables real-time monitoring of grip and foot pressure, aiding training and injury prevention, with further potential in wearables and rehabilitation.

This flexible tactile sensor overcomes limits of IMUs (e.g., Xsens), cameras (e.g., Vicon), and pressure insoles (e.g., Moticon). It directly senses force with high sensitivity (10,692 kPa⁻¹), fast response (0.09 s), and ultra-low power (0.1 V). Using DLP 3D printing, these sensors can be made in minutes at low cost (NTD 100/system). It’s thin, wearable, customizable, and enables real-time grip, step, and motion sensing in sports and rehab. Ideal for scalable, high-resolution smart wearables.

The device targets sports analytics, wearable health, rehabilitation, soft robotics, and smart insoles/gloves. It features customizable size and shape, flexible and lightweight form, and a digital pipeline for rapid tuning. Commercialization includes:
 
 Phase 1 – athlete testing;
 
 Phase 2 – OEM with sports/wearable brands;
 
 Phase 3 – scaling via modular kits (4×4, 8×8), custom services (e.g., insoles), and real-time
