A pulse wave measuring device is provided with a plurality of pulse wave measuring units. Each pulse wave measuring unit has a supporting member to which a beam of a pressure measuring device is attached. Contact portions at the distal end of the beam is in contact with the patient's arm, so that piezoelectric elements mounted on the beam measures the stress variation according to pulsation of the patient's radial artery. The supporting member has two pressing legs between which the contact portions of the beam are situated. The distal ends of the pressing legs are also pressed against the patient's arm. The pressing legs are harder than the radial artery. The interval between the pressing legs can be altered by handling a micrometer head. The contact portions are situated back from the distal ends of the pressing legs.

A power generator using a piezoelectric element is provided which generates electric power at a high efficiency. It has been determined that the efficiency of power generation varies as a function of the ratio of an initial unloaded value of the power generator to a prescribed voltage of the input of an electric power system. A high power generation efficiency can be obtained when the voltage ratio is in the range of approximately two to twenty. In particular, when the voltage ratio is in the range of approximately four to six, a maximum power generation efficiency can be obtained. The invention provides a small-sized, high performance power generator which can be used in practice in portable electronic devices or the like.

A power generator is provided and includes a piezoelectric transducer which generates electric power upon application of a strain. The power generator includes a vibrating arm having a sandwich structure wherein a support layer is held between at least two piezoelectric portions. The vibrating arm is wider on the support end than at a free end. The piezoelectric portions are extended to a root portion of the vibrating arm so that strain energy may efficiently be converted into electric energy. The piezoelectric portions each have a laminated structure so that piezoelectric power generator having the electromotive voltage and the capacitance optimum for charging may be realized.
