The present invention provides a vibration detector device (1) suitable for use as a cochlear implant (12). The detector device (1) comprises a substrate (2) formed and arranged for supporting a plurality of resonator bars (4). The resonator bars (4) are of a uniform length and are supported at each end (6 8) by the substrate material (2). Each of the resonator bars (4) has a distinct resonant frequency characteristic and is arranged with a piezoelectric generator to generate a signal in response to receiving a vibration which causes the resonator bar (4) to vibrate at its resonant frequency.

Why it's free to use
- Filed February 15, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 15, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 15, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
