Vesper Technologies develops piezoelectric MEMS microphones that replace traditional diaphragms and back plates with flexible piezoelectric elements, producing waterproof, dustproof, particle‑resistant and shockproof microphones. Its no‑back‑plate design allows flexible microphone plates to bend and respond to stress without degrading. The piezoelectric approach also reduces power demands, which the company says can enable broader use in voice‑controlled TVs, doorbells, security cameras and augmented‑reality hearables. Vesper has integrated with Amazon AVS and received an endorsement and investment from Amazon through its Alexa Fund. The company raised $23 million to finance commercialization of its piezoelectric microphone technology. Vesper aims to capture a meaningful share of the MEMS and sensor market, which Yole Developpement projects will reach $66 billion by 2021.
