The VTT project is a therapeutic e-Textile device to entertain and comfort people living with dementia, stress and anxiety. It uses the multi-touch eTextile-Synthesizer technologie with a suitable audio transducer, audio amplifier and rechargeable battery pack to create a Vibro-tactile Textile that aim to calm and comfort users.
We have been evaluating vibrotactile transducers to identify the best solution regarding power consumption and vibrotactile feedback efficiency. Thus to improve the vibrotactile feedback quality traditionally made with small DC motors. Through this evaluation we have also selected an efficient resonator material to amplify and transmit generated low frequencies. The battery pack have been chosen for a long autonomy and rechargeable property.
- Audio Transducer : bodyshaker exciter 20W 4ohm
- Resonator material : polypropylene honeycomb plate (Alveolar structure)
- Audio amplifier : 25W subwoofer amplifier
- Battery pack : 12V lithium-ion (3x18650) charger included
- Voltage regulator : 5V Voltage regulator
